Abstract
The use of recycled aggregates in concrete reduces the environmental impact of the construction industry by reducing CO2 emissions and ensuring rational use of natural resources. Several searches were led in many countries to develop the use of demolition waste as components of new concrete. In this context, an experimental program will be undertaken to contribute to the recovery of demolition waste in concrete.
In the concrete mixes the ratios of concrete aggregate range from 0% to 100% with the increment of 25%.
The specimens were tested for compression strength and splitting tensile strength. This research shows that increasing recycle concrete aggregate will decrease the compressive strength and bending tensile strength.
The comparative study between different recycled concrete compositions showed acceptable physical and mechanical properties vis-à-vis the strength. Recycled aggregates can be a substitute material for natural aggregates.
