LIGHT WEIGHT CONCRETE USING ARTIFICIAL PUMICE STONE AS A PARTIAL REPLACEMENT FOR COARSE AGGREGATE

Pumice stones can be used in concrete as lightweight aggregate for casting of structural elements of buildings. Various researches being done with light weight aggregates. The use of Pumice stones in concrete can associate with many advantages in concrete. In this work, Pumice stone is partially replaced the coarse aggregate and mechanical properties are studied. The coarse aggregate is replaced 5%, 10% and 15% by Pumice stone by the weight of coarse aggregate. The tests for mechanical properties are conducted at specified time intervals. And the results were obtained. The properties of materials that are used were found by different tests and satisfied the specifications of Indian standard codes.
