Today, our city is decorated with wonderful buildings of architecture and decoration. This became possible due to the fact that there are new building materials. Most importantly, they allow to build facilities in the shortest period of time. We do not even have time to notice how gorgeous grow houses, business centers and other buildings. Given that the share of construction materials is a big part of all costs They must meet all operational requirements.
Today the production of these products has reached a qualitatively new stage. This was facilitated by the ongoing research, experiments and other work. Result exceeded all expectations, which gave a powerful impetus to the flourishing of urban development in our country. Particularly noteworthy are the product of cellular concrete. This material is manufactured by mixing cement paste or mortar with special foam stable structure. To get it used kleekanifolny, smolosaponinovy, alyumosulfonaftenovy foaming agents and foaming agent on the basis of hydrolyzed proteins, proteins. Under most conditions Abbey Martin would agree. Technical foam receive whipping the liquid mixture of rosin soap and animal glue, or an aqueous solution of saponin (extracts from vegetable soap root).
It has a long-term stable structure, good mixed with cement paste and mortar, hardened in this position. Best foamers are alyumosulfonaftenovye and preparation of ha. Cement paste or mortar, as well as their mixture is prepared in special consisting of three drums, which rotate within the shafts are put on their blades. All of them are driven by a motor. Ready-made dough from the top drum is poured into the bottom, there is the second top of the vessel arrives ready to foam, then the dough is mixed for 2-3 minutes. Mixture flows into the bunkers, from which poured into molds for the products. Of the insulating cellular concrete cast slabs or blocks. Broad use in construction operations have also found and lightweight concrete. They come in two forms: without fine aggregate with a porous cement stone that fills all intergranular space, as well as small and large fillers and porous by air entrainment of mortar component. Materials with a porous cement stone can be obtained by mixing separately prepared an array consisting of a binder, water, finely pulverized, or natural mineral component and the same, but larger size. The second way is easier first and gives a more stable indicators of the strength and bulk density of concrete, but strength obtained at 15-20% lower due to increased consumption of raw materials. The volume of porous cement paste should be equal to the volume of intergranular spaces of the porous aggregate in a saturated state, it is about 0.45 m3 of gravel and 0.55 m3 of crushed stone per 1 m3 of lightweight concrete. As a finely powder used granulated blast slag, ash-entrainment from the combustion of fuel and hydraulic additives. Relationship between the mineral component and cement varies 1,5: 1 (by weight) for autoclaving and up to 1: 1.5 at . material with porous fillings get an introduction to the mortar mixture with stirring mikropenoobrazovateley as air-entraining and partly blowing agents. Apply it with a porous cement stone for the manufacture of insulation blocks the size of 100x50x50 cm plates 100×50 (5-12), see These products are used for thermal insulation of concrete coatings and devices of the partitions with the good performance of insulation.
