Abstract

Demand in the construction sector is increasing, one of which is concrete. The problem that often occurs in concrete is porosity. To reduce porosity, additional materials can be used, namely glass filler and silica fume. The research objective was to determine the effect of silica fume content and cement water factor on the compressive strength of high quality concrete with the addition of glass filler. Variation of cement water factor used is 0.26, 0.4 and 0.5. Variations in silica fume content are 1%, 1.4%, 1.9% and 2.3% by weight of cement. The use of constant 15% glass filler by weight of cement. The results of the study showed that the highest average compressive strength of concrete was FAS 0.5, which was 32.88 MPa with a silica fume content of 1.9%. The highest average compressive strength value of concrete is FAS 0.4, which is 44.92 MPa with a silica fume content of 1.9%. The highest average compressive strength value of concrete is FAS 0.26, which is 51.56 MPa with a silica fume content of 1.4%. From the research results, the highest average compressive strength value of concrete was obtained at FAS 0.26 of 51.56 Mpa.
