PENGARUH VARIASI SILICA FUME DAN WASTE GLASS AGGREGATE PADA CAMPURAN PERVIOUS CONCRETE TANPA CURING

- Pervious concrete is zero-slump, open graded material consisting of cement, coarse aggregate, little or no fine aggregate admixtures and water. It is a special type of concrete having high void content about 15-30%. Because of it, this concrete potential to reduce the run off to the drainage system. In this research, use silica fume (SF) with percentage 0%, 10%, 15%, 20% as substitution cement and waste glass aggregate (WGA) 0%, 2,5%, 7,5%, 12,5% as substitution coarse aggregate. The test method of permeability was according to falling head. Effect of using SF and WGA increase compressive strength in each variation, except the variation which is containing SF 20% and WGA 12,5%. This research show that the maximum of compressive strenght is 10,045 MPa in variation SF 20% and waste WGA 2,5%. The maximum of permeability value is 1,44 cm/s in normal composition pervious concrete. The lowest density is 1630,15 kg/m3 in variation SF 15% and WGA 2,5%. The maximum percentage of WGA in this research is 7,5%.
