Abstract: Water cement ratio is one of the main factors which control the strength of concrete. Though workability of concrete increases due to the increase in water cement ratio strength of concrete decreases considerably. For increasing the workability with minimum water cement ratio, admixtures are used. It is necessary to note that the addition of these admixtures should not decrease strength and durability properties of concrete. Commonly used chemical admixtures are costly. Black liquor sludge is a waste product from paper industry causes environmental pollution, which may be considered to use as a workability aid. This project work is intended to find the amount of black liquor sludge to be added in M30 and M50 concrete mixes for getting a slump of 100 mm with a water cement ratio of 0.35 for medium workability and to study its mechanicaland flexural properties. All the results showed that, black liquor sludge is an effective material for the replacement of current chemical admixtures for improving workability.
