than 1/10 the maximum size of the coarse aggregate represents the void content of the coarse aggregate. For instance, if the void content of a coarse aggregate is 40%, then 40% of the combined fine and coarse aggregate is finer th an 1/10 the maximum size particles for a gradation index of 1.00.
Design CF – The actual lbs. (kg) of cement to be used in a CuYd (cu m) of concrete for this design, known as the ‘design cement factor’. % Air – The design volume of air in the mix by percent of the total volume (CuYd or cu m). Design Slump – The design target for the slump of the mix.

Coarse Aggregate Content. Using the coarse aggregate content table with the given nominal maximum aggregate size of 37.5 mm (1.5 inches) and the given fine aggregate fineness modulus of 2.80, the recommended volume fraction of coarse aggregate is 0.71. This means that the coarse aggregate should occupy 71 percent of the total volume.
Using larger coarse aggregate typically lowers the cost of a concrete mix by reducing cement requirements, the most costly ingredient. Less cement (within reasonable limits for durability) will mean less water if the water-cement (w/c) ratio is kept constant.

The coarse aggregate grading limits are given in IS 383 – 1970 – table 2, Clause 4.1 and 4.2 for single size aggregate as well as graded aggregate. The grading of coarse aggregate is important to get cohesive & dense concrete. The voids left by larger coarse aggregate particles are filled by smaller coarse aggregate particles and so on.
Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse …
