Abstract :
The need of bricks for buildingmaterials is increasing so that the land available for burning bricks is limited. One alternative to overcome this is the use of brick with the main components of cement, sand, water and leather shell powder(Anadara antiquata) and sikacim concrete additive that serves to improve the structure of the brick.The purpose of this study was to obtain the best composition in the manufacture of brickwork. This research was conducted in Concrete Laboratory, Faculty of Engineering, University of Sumatera Utara from April to June 2017using non factorial completely randomized design consisting of 3 levels i.e K1 (5%), K2 (15%) and K3 (25%). Parameters analyzed were specific gravity of aggregate, time of binding, compressive strength and absorption. The results showed that the best treatment was found in the treatment of K1 (5%)with fine aggregate type weight including the bulk density was2.44 gr, saturated surface dry was 2.50 gr, the apparent density was 2.58 gr and water absorption was 2.24% in accordance withBSN1970:2008; The compressive strength was 10.4 MPa and the absorption was 3.89% and according toBSN 03-0349-1989 was on grade I. However, The initial binding time was65 minutes and the final binding time was 120 minutes that was not classified as BSN15-2049-2004.
