    Construction industry presents an attractive market for the use of nonbiodegradable materials, because one of the principal components of construction is concrete, due to its high compressive strength. Incorporating waste glass as coarse aggregate in structural concrete has the potential to not only produce environmental benefits in the reduction of landfill, but to also reduce costs for university building in Nigeria. This paper described the influence of coarse glass on the fresh, hardened properties of concrete and compare to the control (0%) and the Scanning Electron Microscope (SEM) with Energy-Dispersive Spectroscopy (EDS). Coarse aggregate (gavel) was partial replacement with coarse glass aggregates at 5%, 10%, 15% and 20%. Tests are conducted in compliance with British Standard (BS). Mix ratio 1:2.5:3.5 (cement: fine aggregate: coarse aggregate) was used with 0.50 water/cement ratio to produce grade 25 concrete at 28 days. Results showed that slump decreases with increase in coarse glass. 10% partial replacement has good compression of 31.18 N/mm2after 28 days and SEM analysis showed he portion of cracking and bonding effect which denoted the existence of Calcium Silicate Hydrates (C-S-H gel) and Calcium Hydroxide (CH). Therefore, glasscrete showed potential for becoming an additional sustainable solution for waste recycling.
