The construction of cottages in the manufacture of large-block construction parts from silicate mass per 1 m3 of products is spent 150-200 kg of lime. On the details of the same strength (manufactured by mixing mixtures in solutions or concrete mixers with Portland cement), 300-350 kg of cement is spent on the currently appropriate dam. Less weight consumption of lime compared to the cement under these conditions is explained, firstly, by the fact that the lime in autoclave hardening products is only an integral part of the astringent, which is formed when it interacts with the silica of the surface layers of sandstone. As a result of this, the total mass of the cementing substance significantly exceeds the amount of introduced lime. If you build a house, then these sliding systems are perfect for creating the original design of rooms. Secondly, during the hardness of Portland cement, not only calcium hydraulic sodilcates are formed, which are characterized by high strength, but also less durable aluminums and calcium hydraulics. With autoclave firmness of lime-sand masses, only calcium hydraulic sodilicates are formed, similar to the most valuable cement hardening products. Finally, with autoclave hardness of lime-sand masses, the surface of the grains of sand is corroded by lime, and their adhesion with the cementing neoplasm is significantly increased compared to the clutch of the grains of inert aggregate and cement in concrete. As experiments show, from lime-sand masses, with the introduction of ground trepels into a mass of ground, you can also get I not only hollow, continuous and cellular blocks, but also reinforced panels of inter-story and attic floors.
