Impact of Sugarcane Molasses on Compressive Strength and Workability

Abstract

Molasses used as admixture increase the workability, it is a by-product of sugar industry. In this study, mechanical property such as compressive strength and workability of concrete adding fly ash and sugarcane molasses has been investigated. Adding the molasses in concrete increase the compressive strength, delay the initial and final setting time, reduced the bleeding and segregation of concrete and decrease the W/C ratio. The compressive strength test results showed significant strength gain at all ages for 0.15% dosage molasses but peaks at 43.24% at 28 days. Effect of molasses with concentrations of 0.1%, 0.15%, 0.2% and 0.25% by weight of cement, cured at 7, 28 and 56 days were examined. The slump values were observed to increase linearly with increase in dosage of molasses from 0.1% to 0.25% respectively.
