Abstract
The properties of concrete depend partly on the type and mechanical properties of aggregates
used in the concrete mix. The paper presents an investigation designed to study the properties
of pumice lightweight aggregates and assess their suitability to structural lightweight
concrete. The properties of pumice lightweight aggregates mainly aggregates shape, water
absorption, specific gravity and organic impurities were examined. The results indicated that
pumice lightweight aggregates have the flakiness and elongation close to upper limits as set
by BS 812-105.1:1989 low density, high water absorption in comparison to normal weight
aggregates, and are weather resistant. It was concluded that pumice lightweight aggregates
are suitable for manufacture of structural lightweight concrete.
