Abstract
The uncertain tendency to obtain optimum compressive strength and workability values using variations of fly ash or GGBFS mixture substitution, is the background to this study to add reference data. The use of fly ash substitution variations of 15%, 20% ,25% and 30% plan compressive strength f'c= 25 MPa decreased the compressive strength value of concrete with decreases of 18%, 50%, 34% and 42% (7 days), 23%, 56%, 25% and 32% (28 days) respectively from normal concrete. The highest compressive strength is found at 15% fly ash substitution rate of 20.50 Mpa for 7 days and 26.04 Mpa for 28 days. The use of GGBFS substitution variations of 15%, 20% ,25% and 30% decreased the compressive strength value of concrete with decreases of 46%, 56%, 41%, 46% and 42% (7 days), 31%, 29%, 21%, 24% and 35% (28 days) respectively from normal concrete. The highest compressive strength is found at 20% GGBFS substitution rate of 14.78 Mpa for 7 days and 26.82 Mpa for 28 days The use of fly ash substituents with 0%, 15% ,20% ,25% and 30% substitution variations and concrete plan compressive strength f'c= 25 MPa affect the workability value where it is consistent with the initial hypothesis that the average addition of the fly ash substitution variation would lower the slump value. The use of fly ash substituents with 0%, 10% ,15% ,20% ,25% and 30% substitution variations and concrete plan compressive strength f'c= 25 MPa affect the workability value where it is consistent with the initial hypothesis that the average addition of GGBFS substitution variation would raise the slump value Kecenderungan yang belum pasti untuk mendapatkan nilai kuat tekan optimum dan workability baik menggunakan variasi substitusi campuran fly ash atau GGBFS, melatarbelakangi penelitian ini untuk menambah data referensi. Penggunaan variasi substitusi fly ash sebesar 15%, 20%,25% dan 30% rencana
