Abstract

Self-curing concrete is one of the important new types of concrete due to the scarcity of water especially, in the desert areas. Recycling waste demolitions as coarse aggregates for concrete is one of the recent solutions to reduce its bad impact on the environment. In this research, the both types will be combining. This research aims to investigate the behavior of recycled aggregate self-curing concrete under elevated temperatures. The main variables are; aggregate types (recycled vs natural), elevated temperatures (200oC, 400oC, and 600oC), cooling methods (in the air or by using water), and storage time after cooling (for 1 or 28 days). Results are driven in terms of compressive, splitting tensile, flexure, and bond strengths. Test results showed that the recycled aggregate self-curing concrete can be used under elevated temperature considering a strength loss. The use of self-curing and recycled aggregate self-curing concrete may be considered as an alternative solution to the use of conventional curing concrete for infrastructures. Using crushed ceramics as a coarse aggregate at elevated temperature is efficient. The use of recycled aggregate self-curing concrete may consider as an alternative solution to the use of conventionally cured concrete in infrastructures. Firefighting is not recommended by using water due to its bad effects after cooling.
