Abstract

No fines concrete is a concrete that has voids and is made without using sand so that the concrete is much lighter than normal concrete. This reseach, No fines concrete used coarse aggregate (gravel) from Clereng, Kulon Progo, Yogyakarta that had dimension 1 cm – 2 cm. The water-cement ratio was 0,38 and using a superlasticizer f Sika Visconcrete 1003 of 0.5% It calculated from the water that used to add workability and to reduced water up to 30%. The other was using fly ash as filler which has variants 0%, 20%, 40%, and 60% taken from the weight of cement. The cylinder with the height 30 cm and the diameter 15 cm. Compressive strength the concretes were test at 7, 14 and 28 days and for porosity tested at 28 days. The maximum compressive strength occurred in 28 days concrete having a fly ash variant of 40% with a compressive strength of 8.57 MPa. While the lowest result of compressive strength is on 7 days concrete with fly ash variant of 60% that is 2,26 MPa.
