This paper is dedicated for studying the effect of curing methods on the compressive strength of concrete by using five methods of curing which are: the British method which is carried out by immersing the specimens in water starting after 24 hours of casting, then putting them in polyethylene bags- which are closed tightly- till the date of testing .The second method is carried out by covering specimens with burlap and sprinkling the specimens twice a day. The third method is carried out by immersing the specimens with water. The fourth method is carried out by sprinkling the specimens twice a day. And the last method is to paint the specimens with flint coating to prohibit the water from escaping by evaporation. The results showed that the British method is the best one for compressive strength values (36.66,31.26,25.83 MPa(, also the method of immersion in water has a close values to this method especially after 28 days. It has been noticed that the results of the fifth method have the smallest values and for all ages of curing (19.65,19.18,18.24 MPa).
