AB  - Waste from construction and demolition
are one of the main types of wastes produced worldwide.
The aim of this study is to lessen the environmental
problems produced by the dumping of waste from
construction and demolition. This study presents a
comparative analysis of the findings of the experiments
conducted on the properties of fresh and hardened
concrete with different replacement ratios of normal with
recycled coarse aggregate. Recycled aggregate was
produced by crushing the waste concrete from buildings.
Two types of concrete mixtures were tested namely
concrete made fully using normal aggregate as a control
concrete and another type of concrete made using
recycled coarse aggregate (25, 50 and 75% coarse
recycled aggregate replacement were used). Twelve
specimens were utilized for the testing compressive
strength of the basic properties of hardened concrete.
Flexural test of the concrete beams made from the
concrete types were also tested. Irrespective of the
replacement ratio used, recycled aggregate concrete had
a satisfactory performance that did not significantly differ
from the performance of control concrete in this
experimental study. Nevertheless, it is vital to utilize
quality recycled concrete coarse aggregate and to adhere
to the specific rules for designing and producing this type
of new concrete.
