This research work investigates the strength properties (compressive, tensile and flexural strengths) of concrete containing ground glass as a partial replacement for cement. The ground glass was obtained from waste louver blades, ground and sieved to powdery form at 212μm fineness level. Laboratory procedures were used to determine the physical properties such as moisture content, bulk density and specific gravity of the binders and aggregates were also determined. For the compressive and tensile strength tests, sixty (60) cubes of sides 100mm and sixty (60) cylinders of 150mm by 300mm respectively were cast, three (3) samples for each of the percentage replacement groups of 0%, 10%, 20%, 30% and 40% corresponding to the curing ages of 3, 7, 28 and 56 days for each test. Thirty six (36) beams of 100x100x500mm were cast for flexural strength test, three (3) samples for each of the percentage replacement groups of 0%, 20% and 40% corresponding to the curing ages of 3, 7, 28 and 56 days. The specific gravity of ground glass (GG) was found to be3.67 and the bulk density value is 1275kg/m3. The results of the findings show that as the partial replacement of cement with ground glass increases from 10% to 40%, the compressive and tensile strength of specimens for all curing periods of 3 to 56 days decreases. The flexural strength tests show a similar pattern, where there is general decrease in the measured values of flexural strength for all the curing ages as percentage replacement increases. However, it was observed that concrete with 10% replacement of cement with ground glass at 212μm fineness level improves the strength properties of concrete for all the curing period indicating the pozzolanic activity of ground glass.
