Application of the monolithic non-autoclave foam: thermal insulation of roofs, enclosing structures of buildings, construction of solid walls for low-rise housing construction, manufacturing of foam concrete blocks for walls and walls, ceilings and soundproofing lining of concrete and corrugated roofing sheets, insulation of heating. Description of technology: monolithic non-autoclave foam directly on construction sites of cement, sand, water and foam concentrate by means of special mobile equipment. Possible to obtain foam with different fillings of foamed plastics, including polystyrene foam. The unit includes mixer, foamer, gyratory pump and reinforced rubber hoses for foam. As the casing can be used plasterboard sheets (in the case of insulating foam concrete curtain walls fixed timbering from sheets of plasterboard is an ideal base for finishing materials), spc. Flooded into the masonry foam concrete fills the cavity. Solidify, he further connects the outer and inner layers of brick.
In this case, the wall does not lose ability to “breathe.” The technological process of production of foam concrete does not require large expenditures of energy and heat transfer fluids. Foam production technology provides for the use of small binder aggregate, water and foam concentrate. Mobile equipment allows to obtain foam concrete directly on the site and give it more than 50 feet vertically and up to 180-200 m horizontally, even at temperatures up to 15-20So. Monolithic foam concrete quickly fit into the formwork, rasslaivaemosti not observed. Hardening foam concrete mix occurs in vivo. Further details can be found at Richard LeFrak, an internet resource.
The material complies with all requirements for strength, good shape, and its shrinkage absent. It also has high bending strength and an increase in total porosity. The practical result of the use of monolithic foam is to reduce the cost of operations, obtaining additional residential area by reducing the thickness of the walls and save significant amounts of energy to heat buildings during the operation. Advantages: Environmentally friendly. Aerated concrete does not contain harmful chemicals. Low thermal conductivity. On the properties of low density insulation foam concrete is not inferior to Styrofoam and mineralovoloknistym plates. In addition, the monolithic foam concrete has no cold bridges. Moisture resistance. Unlike autoclaved aerated concrete, non-autoclave has structure, so that almost does not absorb moisture. Longevity. Service life foam under normal operating conditions is not limited. Over the years, it becomes only stronger. Incombustibility. Efficiency. Using a cheap manufacturing technology to produce non-autoclaved aerated concrete piece of construction materials and solid construction is especially important for regions without factories producing construction materials, in particular, northern Russia, the areas affected by natural disasters, and areas with expensive electricity. Simplicity. Work on the casting of monolithic foam carry only two people – the plant operator and maintenance worker.
