Abstract:
This experimental study highlights the results of compressive strength tests performed on different specimens of concrete consisting of construction demolition waste and/or glass waste with or without superplasticizer and fiber. The 28-day compressive strength of concrete increases on the use of construction and demolition waste
aggregates compared to that of control specimen. When fine aggregate is replaced with glass waste to the extent of 30%, an increase in compressive strength is observed. Utilization of construction and demolition waste aggregates and glass waste replacing fine aggregate yields improved compressive strength. The replacement of fine aggregate with glass waste including the use of superplasticizer and fiber tends to increase compressive strength. However, if construction and demolition waste aggregates and waste glass replacing fine aggregate including superplasticizer and fiber are used, the compressive strength achieved is less. The construction demolition waste and/or glass waste can be used in concrete yielding improved compressive strength, thereby solving the problem of disposal as well as preserving the environment.
