A Review on Light Weight Vermiculite Concrete

Abstract

Concrete is most using material in the world. In Concrete aggregate occupies nearly 80%. Most of
the aggregates of normal weight Concrete are natural stone such as granite, Lime stone and fine aggregate
sand. Light weight aggregate capable for concrete may be regular materials such as pumice or scoria, or they
may be prepared aggregates such as expanded clays, shale’s, slates and slag’s. Vermiculite is an aggregate that
is created when volcanic rock is heated to intense temperatures. It is being a granular expanded aggregate with
numerous air voids, when mixed with suitable binder develops lighter structure and sound insulating
properties. In recent years research is going on light weight vermiculite materials as replacement for fine and
coarse aggregate in concrete. In this paper an attempt is made to gather all the studies made on light weight
vermiculite concrete in the recent years and put together at one place.
