Lightweight Aggregate

Description

Lightweight Aggregate

Lightweight aggregates are most often used in lightweight aggregate concrete.

Lightweight aggregates are most often used in lightweight aggregate concrete. Compared with normal weight concrete, light aggregate concrete It has been scientifically proven to show strength extraordinary durability and more performance which is related to three factors:

Continuous Internal Healing
Strong aggregate - interfacial cement paste
Compatibility of aggregate modulus and cement past

Launched in 1919, USS SELMA is built with lightweight aggregate concrete with a compressive strength of 26.7 MPa. On In 1980, when scientists performed core tests on the ship, the strength they found increased to 55.2 MPa. This phenomenon never occurs in normal weight concrete.
