Technological influence of temperature in foam concrete preparation technology

An important factor in concrete foam technology is temperature. First, this is the temperature of the outside air and the foam concrete mix when laying. When the temperature drops below +15° C, the time of setting of cement, the set of plastic, and final strength increase. The heat can be added to the hydro mixture directly when it is prepared with hot mixing water or by heating it in a mixer using electricity, steam, or other. With separate technology, part of the heat can be added with foam. Due to the heat introduced into the foam concrete mix during its preparation and the exothermic of the cement during the hardening of the foam concrete, an optimal temperature regime of its retention is provided. The production cycle time is reduced, foam concrete's physical and mechanical properties are improved, and production's technical and economic indicators are increased. The high temperature at an early stage provides a more intensive formation of the cement matrix, which reduces shrinkage phenomena, allowing you to increase the thickness of the layer being laid when concreting structures. The quality of foam concrete is also affected by the method of transporting the mixture to the installation site. A fairly simple and reliable feeding method is pneumotransportation, based on the excess pressure created in barosmesiteli. Piston, diaphragm, and gerotor pumps are also used for pumping the foam concrete mixture. The most effective in practice are recognized gerotornye pumps allowing you to feed the foam concrete mixture at 100 – 150 m horizontally and 50-70 m height. The most favorable conditions for preserving the structure of the foam concrete mixture are provided when applying the crane-bucket scheme. The advantage of this method is the possibility of laying the mixture at any point of the object within the working area of the crane–hook departure. Disadvantages – additional overloads that increase the time of laying the mixture in the formwork and the use of crane time.
