Abstract
This paper presents the experimental study on sandcrete blocks prepared by partially replacing sand with saw dust, ash, rice husk ash. Influence on compressive strength, water absorption capacity and density characteristics are studied by partial replacement percentage of sand with sawdust, ash, rice husk ash. This project with of saw dust, ash, rice husk on solid block ratio of 1:3:8 cement: fine aggregate: coarse aggregate. The result of the various tests are sufficiently encouraging and author suggest to manufacture sandcrete block prepared in proportion of (80% sand+20% saw dust)since compressive strength for this ratio is found to be 4.5 N/MM2 under curing condition and provides optimum & desired result.It also resulted in reduction of heat transfer of sawdust concrete. In the designed concrete the sand was admixture with 20% of saw dust, ash, rice husk. The mechanical properties such as compressive strength were tested for conventional block.
