Development of Rational Parameters of Components of Foam Concrete Composition
A series of articles, devoted to Professor Gorchakov, development of his concept about the dependence of the structure, porosity and properties of building materials on the compositioncontinues. The development of the foam concrete of higher quality with a grade of average density of D400 is theoretically substantiated. This is achieved through the use of afoaming agent with high-expansion foam and a high coefficient of application, multi-component modifiers of mineral and chemical nature in its composition. Special attention is paid toobtaining the rational parameters of components due to the three-level optimization of the disperse composition of the foam concrete. The authors analyze the complex application ofmicro-silica modifiers, super-plasticizer, hardener, fine-disperse slag, and modifier of MB group. It is shown that the three-level optimization is needed for ensuring the action of modifierswith synergy effect for improving the strength, reducing the shrinkage and heat conductivity of the foam concrete.
