Experimental Study on Structural Lightweight Concrete Utilizing Cinder and Pumice as Replacement of Coarse Aggregate

Abstract

Concrete material is been widely used with basalt coarse aggregate throughout the world were the properties and behavior of concrete changes with the materials used, admixtures, water content and w/c ratio. Conventional concrete weight ranges from 2300kg/m³ to 2450kg/m³ and reinforced concrete ranges from 2500 kg/m³ to 2600kg/m³. The self weight of the structure is an important criterion in design point of view and also for economy of construction. Light weight concrete is been popular due to advantages over the conventional concrete, used widely in precast concrete structures. In this project work M30 grade concrete with three mix proportions are considered with granite, pumice and cinder aggregates with proportions of 50%, 75% and 100%.
