Perlite is a naturally occurring siliceous rock of volcanic origins. When heated to more than 1000°C it expands up to several times its original volume and thus creating the premises of light weightiness and thermal insulating properties. The indoor comfortable climate of modern lifestyle requires large amounts of energy to be created and sustained. This, in turn, leads to large amounts of CO2 being released in the atmosphere. Continuous research efforts are invested in creating materials with good insulation properties, be it thermal, acoustic or vibration. The paper presents the experimental results on thermal conductivity of cement-based mortar with different percentage of natural sand being replaced by expanded perlite. Thermal conductivity values were determined at different curing ages up to 28 days. The obtained results shown that lower values of thermal conductivity are obtained with the increase in the replacement percentage, thus proving the suitability of using expanded perlite in rendering plasters and mortars for its thermal insulation characteristics.
