Aggregates U.S. Concrete

Aggregates account for 60% to 75% of the total volume of concrete and are divided into fine and coarse categories. Fine aggregates generally consist of natural sand or crushed stone, with most particles passing through a 3/8-inch sieve. Coarse aggregates are any particles greater than 0.19 inch, but generally range between 3/8 and 1.5 inches in

What is Aggregates Aggregate Definition & its Types.

Aggregate Classification Types of Aggregates. Aggregates are variously classified on the basis of their grain size, their origin, and their volume-weight as follows (1.) Aggregate Types on the basis of Grain Size. This is the most common classification, where in two types of aggregates are distinguished (Fine and Coarse). (i) Fine Aggregates.

Grain size Wikipedia

Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks.The term may also be applied to other granular materials.This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain. A single grain can be composed of several crystals.

How Concrete is Made cement

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.
