The increase in strength between 1 and 28 days is more significant for sugarcane bagasse ash 10%, when compared to other mixtures with sugarcane bagasse ash. The increase in strength may be partly result from the filler effect and the pozzolanic reaction between reactive SiO2 from the sugarcane bagasse ash and Ca(OH)2
from cement hydration. However at 15 and 20% sugarcane bagasse ash results in a decrease in compressive strength, compared to 10% sugarcane bagasse ash admixture samples, due to the dilution effect [5]. The current research further focused to analyse the 10% sugarcane bagasse ash admixture cement paste.
