principles of concrete mix design.ppt - ACC Help

Concrete Mix Design -Definition Concrete mix design is defined as the appropriate selection and proportioning of constituents to produce a concrete with pre-defined characteristics in the fresh and hardened states. In general, concrete mixes are designed in order to achieve a defined workability, strength and durability .

CHAPTER 1 COMPONENTS OF CONCRETE

CHAPTER 1 COMPONENTS OF CONCRETE Concrete is made up of two components, aggregates and paste. Aggregates are generally classi! ed into two groups, ! ne and coarse, and occupy about 60 to 80 percent of the volume of concrete. The paste is composed of cement, water, and entrained air and ordinarily constitutes 20 to 40 percent of the total volume.
