Moisture resistance foam

The new, significantly more stringent requirements snip 03.11.1979, modified 3 Building Heat Engineering require construction companies and construction industry as a whole to increase the thermal resistance of heat building designs in 3 times. To solve this problem by using traditional building materials (brick, wall panels, blocks, etc.) and, accordingly, conventional technology is virtually impossible. Would increase the thickness of the walls a few times, but this is unrealistic. Domestic science was ready to meet the challenge of radically improving thermal performance of building structures. JSC "Newbuilding", part of the Company "Corporation building materials, since 1992 developing domestic technologies insulating foam. In Moscow, Belgorod, Irkutsk, Kaluga, Voskresensk, Rostov-on-Don, Yakutsk assembled and already make products mills for the production of aerated concrete technology JSC "Newbuilding". A processing unit (UMPB) on the production of foam concrete is very compact. With the overall 6h2h4, 2 meters it can be installed in current prices without the production of costly construction work. Installation is made of several blocks quickly mounted and transported on a car "Kamaz" with a trailer. UMPB capacity of 5 m3 / h has a mass of 8 tons, installed power 40 kW, and can submit a solution for the 200 meters horizontally and vertically by 30 meters. When you work 40 hours a week, it is equivalent to a brick factory with capacity of 10 million pieces of bricks per year. You can use it to produce thermal insulation of floors, roofs, pipes, monolithic construction on site, manufacturing units and curly products of different sizes in a hospital. To produce one cubic meter of foam used cement PC-400D20 (350-400 kg), sand (350-400 kg), domestic foaming agents (0,5-1,5 kg) and water. Sand can be replaced with a dry fly ash CHP - where there are heaps of energy enterprises. Foaming agents such as shampoos are not readily available and manufactured by domestic producers. UMPB in different modes can produce insulation foam concrete density of 300-500 kg/m3, thermal insulation material of construction of the density of 600-800 kg/m3, construction material density of 800-1200 kg/m3. If as an example, take the standard block size 20h20h40 cm mark D-600 (GOST 21520-89), then he will have a mass of 15 kg and to replace eight bricks weighing over 35 kg. Due to the high insulating qualities (thermal conductivity 0,11-0,25 W / mK) cellular concrete retain heat well, well protected from noise. The material is well handled by simple tools (sawed, cut, drill). In addition, it fire safe and ecologically clean. Foam concrete water resistance due to closed pores with a diameter of 3 mm. Products are floating in the water without saturation. Foam concrete mixture, covered with a form-building elements, provides a high dimensional accuracy, smooth surface for ease of stripping. Hardening of the finished product without the use of heat treatment is 24 hours. Exterior walls of the foam can be 1,5-2 times thinner, and labor productivity in the clutch is much higher. As a result, a square meter of wall is 2-3 times cheaper. Broad introduction to the practice of building Russia is also important because through it we come to the adopted similar in climatic conditions of the country (Canada, Sweden, etc.) standards energy consumption for heating homes. The ultimate construction products - houses, flats - it becomes competitive, and corresponding to the accepted norms for developed countries. The cost is 330 rubles UMPB. without the cost of commissioning and the costs of transportation.
