Background

Concrete is a composite material formed by binding fine and coarse aggregates with cement (cement paste) and hardening them over time, and in the past, lime-based cements, such as lime paste, have been most commonly used, but hydraulic cements, such as calcium aluminate cement or portland cement, have also been used. Unlike other concretes, non-cement based concretes bond various aggregates directly. Non-cement based concretes include asphalt concretes bonded with asphalt and polymer concretes with polymers as the cementitious material. In which asphalt concrete is often used for road surfaces, when aggregate is mixed with dry portland cement and water, the mixture forms a slurry that is easy to cast and shape. Cement reacts with water and other ingredients to form a hard matrix, which binds the materials together to form a durable rock-like material that has many uses. Admixtures (e.g., pozzolans or superplasticizers) are often added to the mixture to improve the physical properties of the slurry and the final product.
