Development of low thermal conductivity walling material using industrial by-product

This experimental study aims at the feasibility analysis of the industrial waste: co-fired blended ash (CFBA) for the development of low thermal conductivity bricks. The results suggested that the bricks containing 15% CFBA as a partial substitute for sand, complied with the regulations set by Indian standard (IS 1077: 1992d). As well as, thermal conductivity of the CFBA bricks was reduced by 61% in comparison with the commercially available fly ash (FA) bricks. Reduced thermal conductivity of the CFBA bricks further decreased the operational energy demand required for maintaining comfortable temperature (18-27 °C) within the CFBA model house by 57% in comparison with the FA model house.
