Ready Mix Concrete - Structural Guide

Ready Mix Concrete. Ready-mix concrete is concrete that makes in a batching plant according to a mix design. Ready-mix concrete is the type of concrete mix used in construction mostly. Mixing of aggregates (coarse and fine aggregates), cement, water, and admixtures are done to an engineered mix in the batching plant to make ready mix concrete.

Concrete masonry, another type of manufactured concrete, may be best known for its conventional 8 x 8 x 16-inch block. In a few cases concrete is dry batched or prepared at a building construction site. Figure 11.12-1 is a generalized process diagram for concrete batching. The raw materials can be delivered to a plant by rail, truck or barge.

How is temperature controlled in Mass Concrete for

Low heat material. Low-heat generating concrete mixtures are always a wise choice for mass concrete to minimize potential thermal problems. Low-heat generating concrete mixes use the maximum allowable level of low-heat pozzolans— such as Class F fly ash or slag—as cement replacements, and the minimum amount of total cementitious materials that achieves the project requirements.
