Concrete is 2 types:
*Plain Cement Concrete(PCC)*
It is made of a mixture of cement, sand, aggregate and water in definite and required proportion with desirable strength.
*Reinforced Cement Concrete(RCC)*
When plain cement concrete is provided with steel reinforcement, it is known as RCC.
Best mix ratio for PCC is 1:4:8(cement, sand ,aggregate). If concrete is provided with steel bar, the best mix ratio is 1:1.5:3(cement,sand,aggregate).Even Though it is recommended mix , the result can be finalised after conducting cube tests with available materials at site.
