For the design requirement of any concrete structured project to be achieved, close supervision of the project and adequate concrete mix design should be by the civil Engineer involved.
Engineered Concrete Mix Design and Test Methods: A valid analogy is to compare PC to flour and PCC to bread. The book aims to assist students to gain an understanding of PC and PCC through the physical handling and testing of these materials in the laboratory environment.
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.
