Abstract

The development of science and technology, many research has been done on high-quality concrete to overcome the shortcomings of ordinary concrete. To reduce the porosity of the cement, mineral added materials that are pozzolanic and have very fine particles can be used. One of the mineral added materials is fly ash (Fly Ash). The size and size of the porosity are also influenced by the size and size of the FAS (cement water factor) which is used to facilitate work (workability) and increase the compressive strength of concrete. This research was conducted to determine the effect of partial replacement of cement with Fly Ash on the compressive strength of concrete. The composition of cement replacement with various Fly Ash variations is 0%, 6%, 8%, and 10% of the weight of cement. The sample used is cylindrical, the quality of the concrete is 35 MPa, planned for 28 days. Samples were tested at 7 days, 14 days, 21 days, and 28 days with treatment before compressive strength testing. The total sample size was 48 samples consisting of 4 variations and each variation consisting of 12 samples.
