Abstract

Due to the increasing environmental impacts of concrete production, use of wastes as replacement or raw material for other industrial applications is encouraged. Paper lime sludge (PLS) is a waste generated in paper making industries. Several studies had been conducted to investigate the utilization of PLS in concrete production, specifically as a replacement to cement. In this study, a PLS obtained from a paper mill located in Cavite was used as a partial replacement to cement. The effect of PLS as partial Type I Portland cement replacement on the workability and compressive strength of concrete was evaluated. At w/b of 0.5, cement was replaced with 5%, 10%, 15% and 20% by weight of PLS. Results showed that workability and compressive strength of concrete decreased with the increase in amount of PLS. Statistical analysis showed that compressive strength of pure Portland cement concrete has a significant difference with the compressive strength of the blended cement concretes. Nevertheless, the compressive strength of 5 % blended concrete falls under the moderate-strength type of concrete which can be used for structural purposes.
