Influence of Initial Curing on Concrete Characteristics: A Review

Abstract

Concrete curing plays an important part in the production of high-quality concrete. Curing is the method of maintaining the proper temperature and moisture levels in concrete to keep the reaction between water and cement compounds continuous. It is widely acknowledged that concrete needs to be completely cured to attain its ideal properties. For different reasons, the initial curing may not be provided. A significant number of studies have found that delayed curing negatively affects the hardened concrete’s properties. Controlling the moisture content of concrete can increase strength , reduce permeability, and increase durability, especially when exposed to harsh environments. It also improves compressive strength due to the reduction of the void size and ratio. This review deals with the consequences of initial curing delay time, strength grade, mix proportions, and the curing regime on the physical and mechanical properties of concrete. In addition, the variation of some properties of concrete such as strength and durability, according to the curing type and duration, is reported. This topic is very important to site engineers. The factors that affect the results of the compressive strength and durability of concrete have to be taken into consideration; thus, it is advisable to cover it more widely.
