Grades of Concrete with Proportion (Mix Ratio)

Grades of Concrete with Proportion (Mix Ratio) We use different grades of concrete for different parts of the building We could say the grade of concrete is the only thing we do care lot while concreting In this post we are going to explain that in detail Grades of Concrete Actually what do we mean by grade of concrete ? Concrete grades are denoted by M10 M20 M30 according to their

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time In the past limebased cement binders were often used such as lime putty but sometimes with other hydraulic cements such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (for its visual resemblance to
