Experimental investigation of the effect of different curing methods on
the performance of concrete
Abstract
This research was carried out to consider the effect of different curing
methods on the performance of concrete for grade 25 of normal concrete.
The objective of this research was to determine the effect of different
curing methods on the performance of concrete. This study considers the
effect of five curing methods (air curing (B1), water submerged curing
(B3), spraying curing (B2), burlap curing (B4) and moist sand curing
(B5)) were used to evaluate the strength, carbonation, length change,
absorption, and sorptivity of concrete on 3rd , 7th, 14th, 28th and 56th
days at hot air temperature (18-390C) and medium air temperature
(11.2-32.70C). A total number of 210 cube and 30 prisms samples were
cast for all curing methods. The result indicated that water submerged
curing was the highest strength of concrete followed by the close
burlap, spraying, and moist sand curing methods of concrete. The air
curing was the lowest strength of concrete and carbonated concrete in
hot and medium air temperatures. The concluded weak positive correlation
between the strength and the density of concrete. The strength strong
negative correlation with length change, water sorptivity, and water
absorption of concrete at hot and medium air temperatures. Finally, the
water submerged and moist sand curing techniques were the appropriate
techniques for off-site construction of concrete structures; and the
burlap & spraying curing were suitable for off-site and on-site
construction of concrete structural members in hot and medium
environmental conditions.
