The Effect of Curing Methods on Compressive Strength of Concrete

Abstract

Concrete curing is an effort made to optimize the results of concrete casting. This action needs to be done because it has a major effect on the quality and strength of the concrete, one of which is so that the concrete does not lose moisture too quickly, because later this condition will lead to excessive shrinkage in the concrete. As a result, the concrete can experience cracks. This will cause the construction work to be less qualified and endanger construction users. The purpose of this study is to determine the effect of concrete treatment methods on the value of normal concrete compressive strength. Concrete curing can be carried out by several methods according to the type and condition of the structural elements to be treated. From the results of the study, it was found that the curing method of concrete had an effect on the value of normal concrete compressive strength, namely that the average compressive strength value in the fresh water immersion treatment method was 23.730 MPa, the treatment method for wrapping concrete with gunny sacks was 22.349 MPa, the treatment method of wrapping concrete with plastic is 22.306 MPa, and in the treatment method of pouring concrete with fresh water is 21.199 MPa. The average value of the maximum compressive strength occurred in the treatment method with fresh water immersion, namely 23.73 MPa, and the minimum compressive strength value that occurred was found in the treatment method with fresh water sprinkling, namely 21.199 MPa. Thus, that concrete curing is good, namely, by soaking the concrete with fresh water.
