Foam concrete production line (1) is the primary factor to affect the strength of the foam concrete, including the variety and strength grade cement, aggregate type of oven dry density of fly ash, admixtures and foam multiples. (2) foam concrete mix design can be based on a mix of fixed weight method of raw materials and solid volume method. Control unit volume of foam concrete slurry solid set of components and the proportion of solid components optimized. (3) under the premise of the same composition, proportion and preparation process, has a good correlation between the foam concrete compressive strength and oven-dry density. By detecting the wet density of foam concrete, foam concrete and then control the oven dry density, so as to achieve the purpose of controlling foam concrete compressive strength. (4) in the raw material system of cement - fly ash - Foam - Water foam concrete, mixing the right amount of fly ash will help to increase the foam concrete compressive strength, and improve the crack resistance, while reducing production costs.
