Joint and separate methods for preparing a foam concrete mix


An important place in the technology of foam concrete is the method of preparing a foam concrete mixture. There is separate and joint technology. For both methods, the structural and technological parameters of the mixing equipment used significantly impact the quality of foam concrete. The main ones are the shape and geometric volume of the chamber (drum), the type and number of blades( blades), the speed of rotation of the shaft (rotor), and the amount of excess pressure (when cooking in pressure chamber mixers). Joint preparation provides simultaneous loading of components: water, cement, foaming agent, and sand for heat-insulating and structural concrete. Mixing is carried out in various types of pressure chamber turbulence-cavitation mixers. The rotor speed of pressure chamber mixers is proportional to their volume and ranges from 350 to 650 revolutions per minute, depending on the geometric dimensions of the chamber. High-speed mixing provides mechanical activation of the binding materials and intensive foam generation, and the excess pressure in the chamber created by the compressor contributes to the greatest involvement of air in the mixture. A water-cement mixture is first prepared with a separate technology, and sand is introduced, depending on the calculated density. Using a continuous foam generator, for example, the calculated foam amount is prepared and added. Subsequent mixing of the hydro mixture with foam allows you to get a ready-made foam concrete mix with the specified properties, suitable for its installation in forms or formwork.
