| dc.description.abstract | In today’s boom of urbanization, construction of civil infrastructure is very important for any developing country. Particularly, in countries like Ethiopia, cement production is the most useful process for construction purpose despite its carbon emission to the atmosphere. Therefore, efforts are being done to develop some alternative material for concrete production using waste materials. Waste glass powder is one of such alternative materials. This study focuses on strength development and water permeability of concrete containing waste glass powder (WGP) as supplementary cementitious material. Waste glasses were collected from Addis Ababa bottle and glass Share Company, washed, dried and ground to powder. The glass powder was sieved to a particle size of less than 75 micron and its chemical and physical properties were investigated. The setting time and normal consistency of the pastes with OPC, the compressive strength of mortars with OPC and PPC cement, the compressive and flexural strength of OPC concrete shaving a characteristic strength of 30 MPa concrete and finally water permeability of concrete with OPC cement partially replaced by waste glass powder from 5% to 20% cement replacement were studied and compared. The water to cement ratio and amount of cement used for one cubic meter of control concrete mix was 0.55 and 335 kg/m3respectively. The mix design was carried out based on ACI 211, 2002. The compressive strength of concrete with glass powder at the 28 days for 5% and 10% replacement increased by 5.4% and 0.8% respectively; and keeps on decreasing by 4.5% and 7.3% for 15% and 20% replacement respectively. And the water penetration depth of concrete with glass powder at the 28 days for 5% and 10% replacement decreased by 9.3% and 5.1% respectively; and keep on increasing by 3.5% and 8.9% for 15% and 20% replacement respectively. | en_US |
