In the present study, the agro-industrial waste sugarcane bagasse ash (SCBA) was identified as a principal raw material and utilized to develop the sustainable and energy efficient construction products. Many of the previous research studies have been optimized the SCBA content (i.e. partial cement replacement) in concrete production. The reviewed optimum replacement range of SCBA showed a large variation. Such a wide range of optimization is due to the variation in physico-chemical attributes of SCBA collected from different industry sources such as its source (origin), silica content, loss...
