Abstract
Laterite based geopolymer has been widely studied as a sustainable alternative to Portland cement in construction industry. However, its thermal performance is still a challenge due to the low thermal conductivity and low temperature resistance. In this paper, recent studies on the improvement of thermal performance of laterite based geopolymer using additives are reviewed. The additives studied include organic materials, metal oxides and natural fillers. The effect of these additives on the thermal conductivity and temperature resistance of geopolymer is analyzed. The limitations and challenges in the application of these additives in laterite based geopolymer are also discussed. Finally, the conclusion is drawn that the use of these additives can effectively improve the thermal performance of laterite based geopolymer and make it more competitive in the construction industry. As a partial replacement for OPC clinker, a lot of supplemental cementitious materials (SCMs) (industrial and agricultural wastes) are employed nowadays. SCMs cannot be regarded as a universal replacement for cement due to their restricted availability [1,2]. Recently, efforts have been made to substitute waste materials (SCMs) with naturally occurring materials like clay, which contains significant amounts of alumina and silica and can, under the right circumstances, trigger a pozzolanic reaction. Nearly all nations have large amounts of clay
