The process in the conventional civil construction almost always uses raw materials did not renew of natural origin, with intense industrialization, advent of new technologies, population growth and increase of people in urban centers and diversification of the consumption of goods and services, the residues if they had transformed into serious urban problems with an onerous and complex management, considering if accumulated volume and mass, mainly after 1980. The problems if characterized for scarcity of area of deposition of residues caused for the occupation and valuation of urban areas, high social costs in the management of residues, problems of public sanitation and contamination. The amount of solid residues that the sector of the civil construction generates, is each bigger time, therefore it has been a great concern in the whole world, in function of the ambient, economic and social questions. In this way the recycling of these residues, is used in aggregate production becoming an interesting alternative and mainly generating income. The process of P& D (Research and Development) of recycling has as objective to minimize, or even though to eliminate total the residues, with sight to the support in the constructive sector.
The importance of the recycled residue constantly is enhanced, being a great one benefits social. As publication CONAMA n. 307 year 2002, that it determines lines of direction for an effective reduction of ambient impacts provoked by these materials, establishing that the generators are the responsible ones for the produced residue and that with priority objective must be not the generation and in case that is not possible must establish the reduction, reutilizao and recycling. This concept has left of the beginning of that the attendance the basic necessities of the populations in the gift, do not affect the future lives. The use of resources must in accordance with occur the spare capacity of the nature, of form that the growth economic it does not come to attack or to devastate ecosystems violently and can at the same time, to repair the serious problems social.
German Construction Industry

Federal Minister Dr. Peter Ramsauer discussed at the invitation of the initiative ‘Germany builds!’ with industry representatives about the future of the construction industry Munich, 15. January 2013 as the German construction industry in times of specialists and lack of young future evolve? This question was the focus of a high-level Panel discussion under the theme builds Germany! Every man for himself alone “building 2013 leading representatives from politics, industry and science discussed builds on Munich at the invitation of the new industry initiative Germany!”, how will young people for the construction sector will be delighted how businesses can take advantage of synergies and what is necessary, to improve the image of the industry. The construction industry is one of the most important German economic sectors and will require major working in the most diverse areas in the years to come. Almost every eighth job is directly or indirectly dependent on construction activity,”said Dr.
Peter Ramsauer, Federal Minister for transport, building and urban development. A long-term change of image of the construction industry in the public perception to bring, as it builds Germany!”seeks, is therefore a major concern. Only when we us network and learn from each other, can the industry, and with it, the entire economy will benefit permanently. Thanks to my personal experience of the craftsmen to the Economist I know both sides.” Among other participants of the discussion were Ramsauers predecessor Wolfgang Tiefensee, Pierre-Andre de Chalendar (President and General Manager of Compagnie de Saint-Gobain), Prof. Dr. Hans-Jorg Bullinger (former President of the Fraunhofer-Gesellschaft), Jorgen Tang Jensen (Chairman of the Board of the VELUX group) and Annette Hering (Managing Director of Hering Bau GmbH & co. KG).
The round was hosted by Karl-Ulrich Kuhlo, the founder of the news channel n-tv. About 200 spectators and listeners followed the Panel discussion in the meeting place craft forum. Wife Annette Herring stated your point of view as a medium-sized construction company that gets to feel the shortage firsthand: wrongly, many young people still dust, dirt and noise combine with the construction industry.

Why you should decide to build a house your own House offers Mietfreies living without risk of termination financial security and independence of the landlord are only some of the benefits that move the Germans to house building. Even more is that the House is a safe Geldanlageist. The credit is paid off once, then it saves monthly several hundred euros to rent. In addition the value of the House. Who is in a financial squeeze, can always sell his property.
Homeowners have all in all a much higher capacity than tenants. Several, including the Berlin Research Institute studies the empirica.

Abstract diversify power in these times is vitally important for all the companies responsible for producing products like milk and meat, among others. Due to this and the problem of ever-increasing erosion of soils increased, specifically which becomes in gullies, is performed this research take advantage where gullies which are not more than ditches that exist in soils, specifically and in greater proportion and depth where are these – to produce silage; When used to them as silos allow me in the same field to elaborate for the time dry a new food, using the remains of crops and abundance of forages in the rainy season. At the same time that we have protected the gullies of the effect of water erosion and contribute to eliminate them in a time that if well won’t short, if it allows that it is can go restored him vitality to this ground, where economic, social and environmental impact is very high for all the advantages and benefits offered by this technique of producing silage in the gullies of the soil, something that could corroborate in the CPA Abel Santamaria, where it started the investigation; in the subsistence of the Faculty of Agronomy of mountain of San Andres and subsequently in the UBPC Moncada and with some small producers in the region of San Andres y Vinales. In all the places mentioned above this variant is being used to produce food. Table of contents chapters pages introduction material and methods. 6. Results and discussion.
8 Conclusions 17 recommendations 18 Bibliography. 19 Annexes introduction soils are showing for many years in numerous countries, including Cuba, which is not exempt from this, multi-table between medium and severe damage. This situation worsens every day. Degradations are caused by the rapid growth of world population and its economic activities, whose consequences are in over-exploitation, modification of areas covered with vegetation, crushing of soils, as well as levies through toxic, organic and inorganic substances.
Steel Pipes
Posted on November 15, 2016 in News
Metal pipes are made by rolling, welding (or soldered), pressing, drawing, and a combination of these methods, as well as extract from the molten metal and casting. It should be borne in mind that the tubular products turns out not only round, but fitting, as well as a variable cross-section diameter and wall thickness. Metallurgical plants producing pipes from carbon, alloy and high alloy steels, nonferrous metals and alloys of complex composition, bi-metal pipes, etc. Consider the most common methods of production of seamless and welded tubes, obtained using the methods of metal in a plastic condition. Production of seamless pipes hot rolling seamless pipe the manufacture of the first basic operation is flashing round ingot or billet in the sleeve, ie, getting a thick-walled tube. Characteristically, making a hollow sleeve is a very responsible operation that ultimately determines the quality of finished products and the performance of rolling equipment. Firmware harvesting usually is performed in mills, which by design is divided into roll (with obliquely positioned rollers), and disk mills with mushroom rolls. Follow-up sleeves rolled into a tube the required diameter and wall thickness can be performed on automatic mill, the mill pilgrim rolling on a continuous or triple roll mill.
Consider the main features of the receiving tube in these ways. Rolling mills are on automatic seamless pipes diameter of 57-426 mm and wall thickness of 3-30 mm. This method is most common. There is a layout of the equipment automatically mill, and tufted with two automatic one cage for the manufacture of pipes diameter of 140-426 mm. The initial product in this case, use the blank round, obtained by rolling in heavy-and trubozagotovochnyh mills. Workpiece diameter pipes are usually little different from the diameter of the finished pipe. Before rolling the metal is heated in the reheat furnaces or furnaces with a rotating circular hearth. The heated billet after centering the front end of a pneumatic tsentrovatelem for reduction in the flash tube and gage improve the capture of metal rollers comes to piercing mill.
When the firmware receives a blank 2-3.5 times the hood. The maximum value extraction does not exceed 4,5-4,8. Post-processing is performed on an automatic sleeve camp, which is a non-reversible stands duo, in rolls which are arranged sequentially around the gauges. The task of the metal in the rolls in the caliber arbor set, fixed on a long rod so that the gap between sending and gauge determines the thickness of the walls of the rolled tube. The deformation of the metal in this case occurs between the rollers and mandrel, with the addition of thinning the wall has been some reduction in external diameter of the pipe. Since rolling on a round mandrel in a single pass does not provide a uniform deformation of the tube wall on the perimeter, then have to give two and sometimes three passes with the rotation of the tube after each pass through 90 . Hood in one pass, usually no more than 1.4-1.6, and the total may be 1.5-2.1.
Hollywood Productions
Posted on November 1, 2016 in News
Good and sauces beautiful people, on this occasion I am going to introduce a new super direct production of Hollywood. From the creators of: Dear, kitchen with more iron, without cabbage or the Lord of proteins, for all of you waiting for spirulina, part II. And clearly that the director is Steven Spirulina!To be honest, this week we beat the records of questions. By facebook, twitter, web or mail, all consulted the same. That’s why I decided to continue with this theme, but this time directly talk about the chemical composition. If you have not read the previous article Spirulina, the super heroine of feed, better do it and then continuing with this. This algae is consumed our body is nourished with: protein: 55-70% carbohydrates: 15-25% fats (lipids): 5% mineral: 7% water: 3% according to a publication made in 1982 by Dr. Mauricio David spirulina is an ideal nutritional supplement which contains up to 70% proteins, in comparison with the content of the fish which is 20%, meat vaccine 19.3% and the Japanese soy a 34.3%.
It also has a 95% digestibility by what is easily absorbed by the intestinal membranes. The modern criteria to qualify the protein of a food are three: the net utilization of protein (UNP). The amount of the percentage of useful proteins proteins taking into account these criteria, IBN (British Institute of nutrition) synthesizes criteria by multiplying the amount of protein by the net utilization of protein and thus obtained the value of useful proteins from food. According to this criterion, the spirulina ranks second after the egg. FOOD protein useful % UNP %% of protein egg dry whole 44 94 47 40 62 65 Milk powdered Spirulina skimmed 30 82 36 integral soy flour 23 61 37 Brewer’s yeast 23 50 45 wheat germ 18 67 27 to avoid losing custom, I have to warn something.
Microalgae in general, especially the Blue-Green, they have a capacity important to absorb everything that is in the sea, especially heavy metals. Therefore I recommend consuming those that have passed proper sanitary and marketed control in specialized establishments. Now yes, I invite you consult me whatever they want here or by. Write us and we read next week and thanks for continue to choose feed with the heart and not so much with his eyes. Gift them the phrase of the week: not to consume anything that your great-grandmother does not recognize. : Pablito Martin.

Sand Maker Production
Posted on October 23, 2016 in News
Sand making machine is suitable for soft or hard and extremely hard materials crushing, which is widely used in a variety of ores, cement, refractories, aluminum where the soil clinker, emery, glass raw materials, mechanisms built stone gold slag, especially on thesilicon carbide, silicon carbide, sintered bauxite, United States sand contour hard, special hard and corrosion-resistant materials is higher than other types of crushers yield efficacy.Sand maker is also called impact crusher, whose application is wide, not only in hard materials, the great artificial sand used in material performance differences, pre-grinding ultra – fine crushing crushing cement, mining, refractories industry, such as: granite, basalt, limestone, quartz, gneiss, cement clinker, concrete aggregate, ceramic raw materials, iron ore, gold, copper, bauxite, corundum, silica. When the skilled sand maker operators operate the sand making machine, they all have a set of methods which can improve production in the same application environment. Only mastered these methods can we make the enterprises to improve production efficiency, and sand making machine is not prone to problems. Here are the methods we sumarrised to increase the amount of sand making production. First.
We should always pay attention to the tightness of the sand making power transmission belts. If the belt is too loose when in use, it will affect the engine power passes to the sand making machine, when production naturally reduced. So usually use loose belt, we should be fastened in a timely manner. Second, develop the habit of regular inspect internal sand parts wear. Such as Sand internal parts of the impeller and the liner wear is very common, if the serious side of the wear of these parts, while the other side of the lighter wear. At this time will affect the balance of the machine, and great damage to the machine. So when the discovery of these parts wear should timely replacement. But this is important to note, when replacement parts must be replaced at the same time, to ensure the consistency of both sides of the peso.
Otherwise, both sides of the imbalance, the parts will still damage. Third. The internal sand spindle is the main component of sand maker, its balance is important to the normal operation of the machine. But this place is very easy to get wear from time to time, therefore, it is required that we replace these parts when they wear. According to the experience of our technicians. It is more appropriate to replace the sand spindle every 7200 hours, in this period, we can clean the main bear every time, and then add the lubricant fill. Rock crusher: Raymond mill:
First Sound Level Meter

50 Anniversary of the first Sound level meter of the world In 2010 we celebrated the 50 anniversary of Model 2203, the father of all the sound level meters. The sound level meter turns 50 years In 2010 we celebrated the 50 anniversary of Model 2203, the father of all the sound level meters. It was the first sound level meter portable of precision and based on transistors of the world. One made during 21 years and it had sales record of 17,300 units. If to this we added its perfected versions, Models 2204 (Impulsive time constant) and 2209 (detector of tips), it was arrived at a total of 32,700 units. This is the history of the first portable sound level meter of the world, as it was registered in the archives and according to us they told those it lived that it. It does half century, the product presentations were not more than a humble one official notice in the section " The news of fbrica" in the last page of the Magazine Technique of Brel & Kjr.
Number 3 of 1960 included the bulletin that reproduces above. Don Sonmetro Our expert in design of sound level meters during decades, Peter Hedegaard, gives this explanation us of how the portable sound level meter evolved: " Model 2203 was the first portable sound level meter of Brel & Kjr. I am not who to say who was the father of this so special design, but most probable she is than as much P.V. Brel like Gunnar Rasmussen would have something to see, although the final design is attributed to Kay Mller Petersen. What had of special that one design was the frontal in the form of cone, that did possible to place the microphone in the housing without its acoustics was affected of significant form.
