Study On Mechanical Properties Of Light Weight Concrete Using Cinder

Abstract

Light weight concrete plays a major role in reducing the density and increase the thermal
insulation. More environmental and economical benefits can be achieved if waste materials
can be used to replace natural aggregate.. In this study, an attempt has been made to study
the Mechanical Properties of a structural grade light weight concrete M25 using the light
weight aggregate cinder as a partial replacement to coarse aggregate in various percentages
like 0%, 10%, 20%, 40%, 60%, 80% and 100% by volume of natural aggregate and fly ash
as a partial replacement to cement in various percentages like 15%, 20% & 25% by weight
of cement.. The main function of using cinder material is to minimize the cost and to reduce
the disposal of waste material and to reduce the dead load. From the study it is concluded
that the compressive strength, split tensile strength and density are decreased continuously
with the increasing the percentage of cinder aggregate. The optimum (15%) replacement of
cement with fly ash gives better results. The optimum (60%) replacement of coarse aggregate
with cinder provides good strength results. Therefore, the light weight concrete is no way
inferior for construction purpose.
