How to Make Concrete - CEMEX USA - CEMEX

How Concrete is Made: Aggregates. Aggregates, which make up roughly 60% to 75% of ready-mix concrete’s volume, are obtained from quarries and aggregate banks. How Concrete is Made: Additives. Additives are solid or liquid chemical substances that can be added to ready-mix concrete before or during preparation. Most commonly used additives either improve a hardened concrete’s durability or reduce a concrete’s water content in an effort to shorten setting times.

How concrete block is made - material, manufacture, used ...

A concrete block is primarily used as a building material in the construction of walls. It is sometimes called a concrete masonry unit (CMU). A concrete block is one of several precast concrete products used in construction. The term precast refers to the fact that the blocks are formed and hardened before they are brought to the job site. Most concrete blocks have one or more hollow cavities, and their sides may be cast smooth or with a design. In use, concrete blocks are stacked one at a time

How concrete is made - material, manufacture, making, how to ...

Concrete is a hardened building material created by combining a chemically inert mineral aggregate (usually sand, gravel, or crushed stone), a binder (natural or synthetic cement), chemical additives, and water. Although people commonly use the word "cement" as a synonym for concrete, the terms in fact denote different substances: cement, which encompasses a wide variety of fine-ground powders that harden when mixed with water, represents only one of several components in modern concrete. As con
