Greenhouse gas like carbon IV oxides (CO2) leads to global warming and it contributes to about 65% of global warming. The global cement industry emits about 7% of greenhouse gas to the atmosphere. To reduce this environmental hazard, alternative binders are introduced as binders. The replacement proportion was from 5% to 20% for glass aggregates. A total number of 45 cubes were cast using nominal mix ratio of 1:2:4 with water cement ratio of 0.50 and tested for compressive strength at 7, 14, and 28 days. Water absorption tests were carried out at 7, 14 and 28 days of curing age. The results showed that at 28 days of 5% replacement of WGP, the compressive strength was 27.33MPa while that of the conventional concrete at 28 days was 25MPa. A mathematical model was carried out for Flexural strength. The flexural strength at 28 days for convectional concrete was 3.5MPa and at 5% replacement of WGP, the strength was 3.66MPa. It was deduced from the results obtained that the modified concrete attained optimum strength at 5% replacement. This research concludes that the waste glass powder, concrete has a higher strength and durability than conventional concrete and also recommends that the waste glass powder can be used as an alternative construction material for cement. ...Preview Download Preview +Other Civil Engineering project topics and materials you might be interested in»Comparing the compressive strength of concrete made with sand as fine aggregate and with chipping dust as fine aggregate»The comparative study of the compressive strength of concrete made with granite to that made with river round stone (pebble) and local stone»The use of computer in civil engineering»Importance of timber in civil engineering construction»Construction and Installation of a Panel Door»Construction of wardrobe key study on wood work»Effect of street trading on traffic performance and control»Assessment of different types of foundation and their mode of construction»Comparison of soil bearing capacity of different locations in Imo state»Investigation into the suitability of sand and gravel materials commonly used in building construction»Investigating the effect of partial replacement of cement with eggshell powder in concrete production»An investigation in to the causes of cracks in building and possible solutions - a case study of Kukar Gesa community in Katsina metropolis»Suitability of available laterite material in Ilorin East local government area for road construction»Determination of the causes, effects of environmental pollution and its possible control within Kwara and Osun state»Model for prediction of rainfall intensity in Lagos
