Lightweight Aggregate Concrete ScienceDirect

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.

11.20 Lightweight Aggregate Manufacturing

2015-9-10  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.

Lightweight Aggregate Concrete - Properties, Uses

Lightweight aggregate concrete is prepared by using lightweight aggregate or low density aggregate such as volcanic pumice, clay, slate, shale, scoria, tuff and pellite. Concrete is considered to be lightweight is the density is not more than 2200 kg/m 3 , when compared to normal concrete which is 2300-2400 kg/m3 and a proportion of the ...

Lightweight concrete

Concrete is considered to be lightweight is the density is not more than 2200kg/m 3 (the density of normal weight concrete is assumed to be between 2300kg/m 3 and 2400kg/m 3) and a proportion of the aggregate should have a density of less than 2000kg/m 3. Lightweight concrete can be specified using the notation LC for the strength class, e.g ...

lightweight concrete - Post-war building materials

Lightweight 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’ is a term for any particulate material. It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. 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.
