Laboratory Studies for Determining Effect of Sugar on Setting Time of Cement and Properties of Concrete.

Abstract

Cement and Concrete are the most important engineering materials in the construction industry. Atmospheric conditions play crucial roles on the properties of concrete. Hence admixtures are used to maintain standard conditions. Experimental investigations on the effect of sugar on setting time of Birla 53 Grade Cement and properties of concrete made out of it were carried out for different percentages of Sugar (0.00, 0.03, 0.05, 0.06, 0.08, 0.15 and 0.2%) by weight of cement and water cement ratios 0.5 & 0.35. Initial setting time of concrete retarded upto 0.08% sugar content. Slump varied from Shear to Collapse with increase in Sugar content at 0.5 w/c ratio, and it changed from shear to true for 0.35 w/c ratio. Compressive strength showed increasing values with increase in sugar contents for all the specimens, In particular a 40% increase in the compressive strength when the sugar content was 0.06% and the concrete made of 0.35 w/c ratio. Similarly, Split tensile strength of cylinders also increasing trend with increase in sugar content
