Concrete Concrete is a stone like substance obtained by permitting a carefully proportioned mixture of cement sand and gravel or other aggregate and water to harden in forms of the shape and of dimensions of the desired structure Reinforced cement concrete Since concrete is a brittle material and is strong in compression It is weak in tension so steel is used inside concrete for

Mortar Mix Ratios Cement Sand Gravel Mortar Types and Uses Typically used as the compound for joining masonry stone or ceramic units together mortar is made by combining cement lime and sand Mortar typically has a higher water to cement ratio when compared with concrete which allows greater workability and is required to form mortars

The reason concrete cannot be made simply by mixing sand with cement is that it is a composite material that needs a coarse aggregate to achieve this strength In essence concrete is a mixture of Portland cement water sand and rocks The cement or paste coats and binds the sand and rocks Then a chemical reaction called hydration which is
