Effect of Curing Methods on Compressive Strength Of Concrete 15 2. Review of Related Literatures In concrete technology, the maintenance of the drying and setting process is referred to as curing. The purpose of curing is to keep ad-equate moisture content and temperature as soon as the concrete is placed and nished.

Curing is a crucial process in construction, particularly when it comes to concrete structures. It involves maintaining adequate moisture, temperature, and time to allow the concrete to achieve its desired strength and durability. Let's dive into what curing is, why it's important, and how it's done, along with some real-life applications

The population growth resulted in a sharp surge in construction work. Water is required for the mixing, curing and monitoring of cement hydration processes in concrete. In self-curing concrete, the availability of additional internal water that was not mixed in, causes the cement to hydrate. Due to the fact that concrete cures from the …

curing this is achieved by external curing applied after mixing, placing and finishing. Self-curing or internal curing is a technique that can be used to provide additional moisture in concrete for more effective hydration of cement and reduced self-desiccation. A.

Effect of Impurities in Curing Water on Concrete Construction The main intention of curing is to let the water penetrate the concrete. No water is necessary for curing if proper steps were taken to prevent the loss of water from the concrete. There is inevitably some loss of water from the surface of the structural members due to evaporation.
