The use of fly ash waste as an ingredient in the manufacture of concrete is a step taken to reduce adverse impacts on the environment. Fly ash can be used as a substitute for cement in concrete, commonly called geopolymer concrete. Geopolymer concrete must use high temperature curing in order to accelerate polymerization and increase its strength. The addition of cement to geopolymer concrete, commonly known as hybrid geopolymer concrete, can be a solution to help with room temperature curing. The purpose of this study was to examine the effect of variations in the use of geopolymer materials and cement on the strength of hybrid geopolymer concrete. Tests include concrete slump, fresh concrete volume weight, concrete compressive strength, and concrete flexural strength. This research uses fly ash geopolymer material and 10% silica fume as a substitute for cement. variations in the use of geopolymer and cement materials, namely, GP100, GP75: PCC25, GP50: PCC50, and GP25: PCC75. Curing was carried out for 7, 28, and 56 days at room temperature. The test results show that the compressive strength and flexural strength of concrete increase with age. The compressive strength test shows the highest compressive strength value in concrete with variations in the use of 25% geopolymer material and 75% PCC cement (GP25-PCC75), which is 35.22 MPa at the age of 56 days. Flexural strength testing showed the highest results also in concrete with variations in the use of 25% geopolymer material and 75% PCC cement (GP25-PCC75) of 4.45 MPa at the age of 56 days. Based on these test results, hybrid geopolymer concrete shows good potential to be used as an innovation in the field of concrete technology because it can increase the strength of concrete.
