Abstract

The global warming is caused by the emission of greenhouse gases such as CO2 to the atmosphere. The global cement industry contributes to about 7% of greenhouse gas emission to the atmosphere. Consequently, efforts have been made in the concrete industry to use wastes as supplementary cementing materials (SCMs). Waste glass is a materials when ground to a very fine powder exhibits pozzolanic properties which can be used as a partial replacement for cement in concrete. In this paper, an attempt has been made to studied the durability of high performance concrete (HPC) containing ground waste glass (GWG) as partial replacement of cement in the range 0% to 25% at an interval of 5%.The effects of GWG on compressive strength at the ages of 3, 7, 28, 56 and 90 days, water absorption, acid (H2SO4) and salt (MgSO4) attack at 7, 14 28 and 56 days immersion period and elevated temperature at a maximum temperature of 500 o C were investigated. It was discovered that, GWG improves the compressive strength, water absorption and resistance of HPC to H2SO4 and MgSO4 aggression, while the performance is poor when subjected to elevated temperature. Also, the compressive strength improves with curing age while durability reduces with exposure duration. Furthermore, an optimum GWG content of 10% is recommended for grade 50 HPC.
