LECA Light Weight Concrete AggregatesAdvances in Lightweight Concrete Construction Magazine

LECA is a special type of light aggregates that has been pelletized and fired in a rotary kiln at a very high temperature As it is fired the organic compounds are burn off forcing the pellets to expand and become honeycombed while the outside surface of each granule melts and is sinteredThere are two ways saturated lightweight aggregate can help produce better concrete First with a typical mix the transfer of moisture into and out of the lightweight aggregate particle prevents the buildup of a high w/c ratio area at the contact between the paste and the aggregate

What is lightweight concrete QuoraUnderstanding the Density of Concrete Aggregate Research

Lightweight aggregates are placed instead of coarse aggregates in concrete is called Lightweight concrete The density of lightweight concrete in the range between 300 to Kg/cum and the normal concrete density to Kg/cumLightweight concrete uses pumice a very lightweight mineral as aggregate One way to determine the density of concrete is to first determine the density of the materials that go into it Cement weighs 830 to 1 650 kilograms per cubic meter equal to a range of 52 lbs per cubic foot to 103 lbs per cubic foot
