Abstract
Thermal conductivity is one among the most important thermal property of any material which affects the transfer of heat through conduction. Loss of heat through roofs and walls has an adverse effect building’s energy consumption. The nature of Cementitious material, moisture content, aggregate type, temperature and density are the key aspects imparting thermal conductivity. This paper focuses on Silica Aerogel synthesis and its effective application in cement mortar inheriting the thermal conductivity property. The purpose of present work is to examine the microstructure of cement Mortar 1:3 inclusive of Aerogel as a partial replacement of cement ranging from 0 to 6% by weight and to ascertain the strength along with durability characteristics. Aerogel is synthesized in the laboratory by Sol-gel process and characterized for element composition and size. The results showed that; Cement Mortar strength and its durability values are promising for 5% replacement of Silica Aerogel for 3, 7 & 28days of curing.
