HISTORY OF LIGHTWEIGHT CONCRETE

The use of lightweight (LWAC) can be traced to as early as

3,000BC, when Mohenjo-Daro and Harappa were built during the Indus

Valley civilization. In Europe, the use of LWCA occurred 2,000 years

ago when the Romans built Pantheon, the aqua ducts, and the Coliseum in

Rome. The pumice is still used today in certain countries, such as Germa-

ny, Italy and Japan. In some places like Malaysia, palm oil shells are used

for making LWAC.

The Roman Temple Constructed using LWAC

Earlier lightweight aggregates (LWAs) were of natural origin,

mostly volcanic: pumice, tuff. They function as active pozzolanic materi-

als when used when used as fine aggregates. Techniques have been de-

veloped to produce them in factories. These are produced from the natural

raw materials like expanded clay, shale, slate, etc., as well as from by-

 products such as fly ash, blast furnace slag, etc.
