<br/><br/> This paper deals with a review on investigation of perlite based on its mechanical strength and its thermal property. The investigation shows that the perlite has the property of lightweight due to its porous nature and can be partially replaced with sand since it contains SiO2 content to a great extent. Due to its porous nature, the researchers say that the perlite in concrete induces thermal insulation property for which the increase in the perlite content decreases the thermal conductivity. But with increase in perlite content, there is a subsequent decrease in the mechanical strength of concrete. This paper consolidates different testing carried out to determine the performance of perlite in concrete in terms of strength and thermal properties<br/>
