Abstract
Abstract. This study assessed the effect of paving blocks product using basalt minerals with variation concentration. The raw material for producing paving blocks such as cement, sand, andesite, and water. The paving block was made with and without basalt over concentration 5 %, 15 %, 25 %, and 35 %. The powder was sifted using mesh sieve of 60 and 80. Then, the paving block product was analyzed by XRD, XRF. The analysis physical properties of the paving block such as compressive strength (SNI 03-2493-1991), density (ASTM D-854), absorption (SNI 1969-2008), porosity (SNI 1969- 2008). The characterization from XRD showed the formed phase such as Gismondine, Calcite, C-S-H, and Quartz. Based on the XRF characterization, the content of CaO was decreased in the paving block because of the addition of basalt as a cement substitute. The results from compressive strength showed a paving block without basalt addition has 8.612 MPa compressive strength and 8.89 % absorption. While the addition of a basalt concentration of 5 % with 60 mesh has compressive strengths of 9.684 MPa and absorption of 9.29 %. With basalt concentration 10 % over 80 mesh, it compressive strengths of 9.748 MPa and absorption of 9.48 %.
