Abstract
Concrete is undoubtedly the backbone of the construction industry. On the other hand, to produce concrete requires a considerable amount of natural resources so as to satisfy the demands on the market. This experimental paper investigated the effect of partially substituting fine aggregate with recycled glass to produce high strength concrete in order to alleviate the burden on the natural sources. A conventional high strength concrete was compared to different mixes containing glass aggregates as a replacement for fine aggregate at levels 10%, 25%, 50% and 75%. All the specimens were tested at 1-, 3-, 7-, 14- and 28-days air cured. Different types of tests were conducted and accurate data were collected and fully achieved and it can be noted that with increasing percentage of glass the compressive strength of concrete has a tendency to decrease. The maximum compressive strength for 10% and 75% were 48.81MPa and 32.11MPa respectively. The range of fresh density of glass concrete was found to be from 2237-1896 kg/m3.
