Abstract: By progress in constructing, necessity of destroying or repairing old constructions improves relatively; therefore large amounts of demolitions and waste materials remain in environment.
Reusing waste materials is a practical solution to protect the environment, which could save energy, cost of disposing them to landfills and protect the environmental conditions. In order to have a better usage of waste materials, we should gain more recognition of their influences on concrete. In this research, some waste materials are substituted by natural aggregates in concrete.
Reaching experimental-mathematical formulas between some mechanical properties of concrete containing waste materials is the main purpose of this research. In this paper, three different waste materials including glass, recycled concrete aggregate and plastic are substituted by natural aggregates. Substitution percent for these three waste materials were 0, 5, 10, 15 and 20.
Waste glass and waste plastic were replaced by natural fine aggregates, and recycled concrete aggregate was replaced by both fine and coarse natural aggregate. Mechanical properties considered in this research were compressive strength, tensile strength, and flexural strength.
Also some relations were investigated between these mechanical properties and were compared by other researchers’ results.
