Abstract

Bricks are building materials that contain compounds that can increase the compressive strength of a building. This research utilized waste bricks as a substitute for pozzolan for cement manufacture. Testing of waste bricks using the reactivity index test method, characterization with XRD and XRF. Cement powder was tested chemically, and determined the value of its compressive strength on the mortar test object. The results of the characterization of XRF instruments are SiO2, Al2O3, Fe2O3 with minor compounds including CaO, ZnO, TiO2, K2O, P2O5, CuO, V2O5, Cr2O3, MnO, SrO, Eu2O3, and Re2O7. Meanwhile,BaO is owned only by the first and third bricks, while PbO is owned by the first. The number of SiO2, Al2O3, and Fe2O3 compounds has met the quality requirements as pozzolanic materials(>70%), namely 84.20% of the first sample, 83.70% of the second sample, and 84.30% of the third sample. The reactivity index test also met the target (>75%), namely 75.60% of the first sample, 75.00% of the second sample, and 77.90% of the third sample. The higher the content and the reactiveness of an oxide compound in the waste bricks are directly proportional to the quality of the cement
