ABSTRACT
This study aimed to determine the effect of Groundnut Shell Powder (GSP) on the concrete compressive strength as a partial substitute for cement with a variation of 0%, 5%, 7.5%, 10%, and 12.5%. The composition of the concrete mix consists of coarse aggregate with a maximum aggregate diameter of 19.1 mm and Portland cement Type I. The additional material uses groundnut shell powder which is processed through drying and grinding then sieved to pass sieve no.200, then mixed in concrete as a partial replacement of cement. The concrete test object is a cylinder 15 cm in diameter and 30 cm in height. The compressive strength of concrete is tested at 14 and 28 days. The results of the average compressive strength at the age of 14 days were with variations of 0%, 5%, 7.5%, 10%, and 12.5%, respectively (MPa) 18.495, 23.590, 22.930, 17.174, and 13.777, while at the age of 28 days respectively (MPa) 26.610, 24.157, 19.816, 18.684, 16.608. Optimum compressive strength values of 14- and 28-days age were in the 5% percentage, namely 23.590 and 24.157 MPa. The lowest decrease also occurred at the percentage of 12.5%, namely 13.777 and 18.684 MPa. Based on the results shown, there is upsurge in compressive strength, however increasing the percentage of GSP makes the compressive strength of concrete decrease.
