Abstract
This study investigates the compressive strength and properties of concrete produced from the partial replacement of fine aggregate with crushed waste glass thereby providing a reusable approach to waste glass bottles in concrete production. This experiment was focused on finding the best mix ratio with crushed glass replacing 5%, 10%, 15% and 20% of fine aggregate with the most desirable properties that would be effective in concrete works. Sieve analysis, bulk density, slump test and compressive strength test were carried out on the materials, fresh and hardened concrete. The results indicated that the average compressive strength for 7 days ranged from 14.15-15.49Nm, the 14 days ranged from 14.32-15.56Nm, the 21days values were between 15.06-16.00Nm, the 28days average compressive strength ranged from 20.00-20.60Nm, all with 0.50w/c ratio. It was discovered that adding waste glass to the mixture increased the compressive strength up until the ideal amount of replacement.
