Lightweight aggregates are made by a thermal process using natural materials such as clay, shale, slate, perlite, and vermiculite. The production process of lightweight aggregate depends upon the raw materials used. Basically, there are two processes for making lightweight aggregates—a wet process and a dry process.

دردشة على الإنترنت Read More2015-9-10 lightweight aggregate, the raw material (excluding pumice) is expanded to about twice the original volume of the raw material. The expanded material has properties similar to natural aggregate, but is less dense and therefore yields a lighter concrete product. The production of lightweight aggregate begins with mining or quarrying the raw material.

دردشة على الإنترنت Read MoreLightweight concrete is a collective term for different types of concrete which are all characterized by a low specific weight. The reduced density is achieved by adding specific ingredients to the mixture or by means of special production techniques, resulting in a weight decrease from 2.000 or 2.500 kg/m³ for ‘ordinary’ concrete to approx. 500 []

Aggregate may be natural, manufactured or recycled. • Aggregates make up some 60 -80% of the concrete mix. They provide compressive strength and bulk to concrete.
