Annotatsiya
Concrete is made up of two components, aggregates and paste. Aggregates are generally classified into two groups, fine and coarse, and occupy about 60 to 80 percent of the volume of concrete. The paste is composed of cement, water, and entrained air and ordinarily constitutes 20 to 40 percent of the total volume. In properly made concrete, the aggregate should consist of particles having adequate strength and weather resistance and should not contain materials having injurious effects.
