WASTE CEMENT AND CONCRETE MANAGEMENT AS COSTEFFECTIVE AND ENVIRONMENT FRIENDLY: PRINCIPLES AND PERSPECTIVES

The use of recycled aggregates in concrete opens a whole new range of possibilities in the reuse of materials in the building industry. The utilization of recycled aggregates is a good solution to the problem of an excess of waste material, provided that the desired final product quality is reached. The studies on the use of recycled aggregates have been going on for 50 years. In fact, none of the results showed that recycled aggregates are unsuitable for structural use. Using the recycled aggregate is a cost-affective and environmental friendly solution which is required general waste concrete management knowledge. This paper is focusing on waste cement and concrete management for optimizing the construction costs. The ways for reducing the green house gases (GHG) at cement and batch plants are suggested. A comparison among Iran industrial utilized cement volume and other countries was performed. Finally, it can be concluded that application of recycling concrete could reduce the costs by reducing truck traffic, providing the Non- Renewable Resource, Better Trucking Utilization (Reduced Costs), Allow down to 10% Deleterious Materials in Iran.
