Abstract: Concrete is very important construction material. The main composition of concrete is cement (OPC), coarse aggregate (blasted rubble), fine aggregate (sand) and water. This study aims to introduce a low cost admixture which is a waste product from paper industry which are disposed to water resources and causing serious environmental problems .So, by incorporating PBL to concrete pollution can be reduced and the properties of concrete can be improved. Here we are trying to study the effect of pulp black liquor (PBL) as an admixture in concrete. The investigation is made by using the pulp black liquor from Hindustan Newsprint Limited Vellore (HNL) .The properties of pulp black liquor and its performance on concrete with three different design mixes and setting times of cement (OPC) were observed. The results shows that pulp black liquor increases the strength of concrete, improves compaction, reduces honey combing and retards the initial setting time and final setting time of concrete.
