Properties of Concrete - Portland Cement Association

This reduction of paste-aggregate bond reduces concrete strengths. Bleeding. The bleeding properties of fresh concrete can be determined by two methods described in ASTM C232, Standard Test Methods for Bleeding of Concrete (AASHTO T 158). The bleeding rate and bleeding capacity increases with initial water content, concrete height, and pressure.

Cement Concrete

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

Alkali-Aggregate Reaction

Alkali-Aggregate Reaction. In most concrete, aggregates are more or less chemically inert. However, some aggregates react with the alkali hydroxides in concrete, causing expansion and cracking over a period of many years. This alkali-aggregate reaction has two forms: alkali-silica reaction (ASR) and alkali-carbonate reaction (ACR).
