Abstract EN
This paper is devoted to investigate the effect of internal curing technique on the properties of self-compacting concrete (SCC).
In this study, SCC is produced by using silica fume (SF) as partial replacement by weight of cement with percentage of (5%), sand is partially replaced by volume with saturated fine lightweight aggregate (LWA) which is thermostone chips as internal curing material in three percentages of (5%, 10% and 15%) for SCC, two external curing conditions water and air.
The experimental work was divided into three parts: in the first part, the workability tests of fresh SCC were conducted.
The second part included conducting compressive strength test and modulus of rupture test at ages of (7, 28 and 90).
The third part included the shrinkage test, at ages (7, 14, 21, 28) days.
The results show that internally cured SCC has the best workability, and the best properties of hardened concrete which include (compressive strength and modulus of rupture) then the externally cured SCC with both water and air as compared with reference concretes.
Also, the hardened properties of internally cured SCC with replacement percentage of (10%) by thermostone chips is the best as compared with that of percentages (5% and 15%) for both external curing conditions.
In general, the results of shrinkage test, showed reduction in shrinkage of internally cured SCC as compared with reference concrete.
