How Concrete is Made - Portland Cement Association

How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

Use of Water Reducers, Retarders, and Superplasticizer

Use of Water Reducers, Retarders, and Superplasticizers. Introduction. Many important characteristics of concrete are influenced by the ratio (by weight) of water to cementitious materials (w/cm) used in the mixture. By reducing the amount of water, the cement paste will have higher density, which results in higher paste quality.

Major Problems in Concrete Pumping Works: How to Avoid

Feb 12, 2021 · Improper mixing of concrete constituents leads to segregation in the mix, and hence in failed concrete pumping. Adequate mixing of concrete components ensures that aggregates have a full coating of cement grout to lubricate the mixture as it is being pumped. When concrete mix remains in hot weather for a longer period of time, the concrete will stiffen and lose its pumpability to a great extent. …
