Effect of Granulometric Component Composition in Cellular Concrete on Cement Consumption Rate

Article Preview

The use of local natural and technogenic raw materialsallows expansion of the raw material base for producing the building materials and reduction of production cost. Creation of low energy-intensive technologies for producing the building materials is a priority for the construction industry. The chemical and mineralogical composition of industrial wastes makes it possible to use them for producing the low-clinker or clinker-free composite binders. Secondary resources can be used as an active mineral additive that would allow to reduce the cement consumption. The properties of cellular concrete depend on the formed cement matrix structure, the strength of the inter-pore partitions. Quality can be managed by directional formation of the mechanical framework. Providing the necessary granulometric composition of the cellular concrete components is decisive for the mechanical framework formation. The inter-pore partition structure in the cellular concrete is a developed silicate matrix formed by hydration products and a siliceous component. Therefore, when designing this structure, an analogy with ordinary dense concrete is quite possible. The basic principle for designing the concrete composition consists in creating a dense packaging of the constituent components.
