PENGARUH VARIASI FLY ASH DAN WASTE GLASS AGGREGATE PADA CAMPURAN PERVIOUS CONCRETE TANPA CURING
Daftar Isi:
- Concrete is one of the construction materials that is very well known and often used until now. Pervious concrete is used as a solution to the problem of lack of water catchment areas. In the process of carrying out construction in the field, concrete treatments are often ignored by workers. Therefore, in this study type F fly ash will be used because there is a content of chemical compounds SiO2 + Al2O3 + Fe2O3 at least 70% compared to type C with a content of chemical compounds that are only at least 50% as a substitute for cement and waste glass aggregate as aggregate substitution rough designed not to do treatment. Variations of fly ash used were 0%, 30%, 40% and 50% while for waste glass aggregate 0%, 2.5%, 7.5% and 12.5%. The results showed that the effect of using fly ash and waste glass aggregate increased when the use of these materials was less. The most optimum compressive strength results obtained from 30% fly ash and 2.5% waste glass aggregate which is equal to 10.290 Mpa. While the results of the most optimum permeability of 0% fly ash and 0% waste glass aggregate is 1.44 cm / s and the weight of the concrete decreases if the use of fly ash and waste glass aggregate increases. This is because the specific gravity of glass aggregates and fly ash is lighter.
