Concrete Mix Design Procedure and Example IS456

🕑 Reading time: 1 minute 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 aggregate.

For example, consider a concrete mix design that calls for 282-pounds of water (i.e. free-water) and contains 1100 pounds of fine aggregate and 2000 pounds of coarse aggregate. The mix design shows fine aggregate absorption to be 2% and coarse aggregate absorption to be 1%. The batch plant operator measures the aggregate moisture and finds

Stationary Mixing. Concrete is sometimes mixed at the jobsite in a stationary mixer or a paving mixer (Fig. 10-2). Stationary mixers include both onsite mixers and central mixers in ready mix plants. They are available in sizes up to 9.0 m. 3 (12 yd. 3) and can be of the tilting or nontilting type or the open-top revolving blade or paddle type. All types may

Mar 18, 2017 · There are two categories of ready-mixed concrete: central-mixed and transit mixed or truck mixed. In the first category, mixing is done in a central plant and then concrete is transported in an agitator truck. In the second category, the materials are batched at a central plant but are mixed in a truck. Concrete Placing and Compaction of Concrete
