When constructing monolithic structures made of foam concrete


When constructing monolithic structures made of foam concrete, it is necessary to observe the temperature conditions of holding and drying and the design features of formwork systems. The greatest problems arise at low positive and, especially, at negative outdoor temperatures. In the construction of massive and medium massive structures, use the methods of the thermos and pre-heating of the mixture. Significant consumption of high-quality cement from - 400 to 450 kg / m3 releases 14000-18000 kJ/m3 of exothermic heat, sufficient to ensure optimal temperature and humidity conditions of aging. For small massive, and thin-walled structures, the thermos and preheating methods must be combined with the use of thermoactive formwork, thermometers, a hothouse device, or others. When the foam concrete mixture loses its survivability, a stable frame of the cement matrix is formed to preserve the pore walls, excluding concrete sediment. The cast consists of the foam concrete mix with a high water-cement ratio and has both positive and negative sides. A positive feature is the high workability and filling of all pores, niches, and other structural elements. Lack of increased requirements for the tightness of the formwork or elements of enclosing structures that perform the functions of fixed formwork. The high free water content in the hardening foam concrete requires using formwork materials that can provide a holding and drying mode.
