The use of Lightweight concretes has gained acceptance and popularity world wide in the recent years in the construction and development of both the infrastructure and residential buildings. The properties of volcanic pumice lightweight aggregates obtained from Longonot in Mai Mahiu area in Kenya was experimentally investigated and this study presents the experimental results of the investigation. Three samples of the lightweight aggregates were investigated and their properties compared with those of the conventional normal aggregate. In this experimental investigation the physical and mechanical properties of the aggregates were investigated. Properties such as bulk density, water absorption, grading and aggregate impact crushing value were determined.
