Mix Design in concrete & factor influence

Mix Design :

Concrete mix design is a process of selecting suitable ingredients for concrete and determining their proportions which would produce, as economically as possible a concrete that satisfies the job requirements i.e., concrete having a certain minimum compressive strength, workability and durability. The proportioning of the ingredients of concrete is an important phase of concrete technology.

Factor influence :

1)Grade Designation.

2)Types and grade of cement.

3)Maximum nominal size of aggregate.

4)Grading of combined aggregates.

5)Water-cement ratio.

6)Workability.

7)Durability.

8)Quality control.
