By-products from a number of industrial processes are used as alternative supplementary cementitious
materials in concrete. Sugarcane bagasse ash is mainly composed of amorphous silica and can be used as
a pozzolanic material in concrete. Production of sugarcane bagasse ash (SCBA) based blended cements
with different replacement levels of SCBA, and the performance of concrete with these cements in terms
of compressive strength, heat of hydration, drying shrinkage and durability are discussed in this paper.
Durability performance was investigated by five different methods in this study, namely oxygen
permeability test, rapid chloride penetration test, chloride conductivity test, water sorptivity test, DIN
water permeability test and Torrent air permeability test. The results from this study show that use of
sugarcane bagasse ash in concrete prominently enhances its performance. Low heat of hydration, additional
strength gain due to pozzolanic reaction, significant reduction in permeability because of pore
refinement and similar drying shrinkage behavior were observed for bagasse ash blended concrete compared
to control concrete.
