Abstract: Warmth acquired through the top of the structure is the real reason for unconditioned structure or the real burden for the cooled structure. Vermiculite being a phyllosilicate group of hydrated magnesium-aluminium-iron silicate is an inert material which resists the heat penetration. This project mainly aims at the development and evaluation of vermiculite mortar which exhibits low water assimilation, better quality properties, low heat penetration and better thermal insulation, when compared with traditional method of plastering. The utilization of this material reductions the basic weight. Different blends were readied utilizing distinctive level of vermiculite and water-concrete proportion. The cement mortar cubes of dimensions 70.6 mm were casted with replacement of fine aggregate with vermiculite in the ratio of 1:3. The fine aggregate was replaced with vermiculite in the fashion of 0.5 parts, 1 parts, 1.5 parts, 2 parts and 2.5 parts. Vermiculite mortar is light in weight when compared to cement mortar in the range of 5 to 48%. The replacement of 33.33% fine aggregate with vermiculite shows higher compressive strength.
