Curing: As with any type of concrete, curing makes moisture available for hydration, which is the chemical reaction that causes concrete to harden and gain strength. A water cure sprays or irrigates the RCC to keep it moist. A spray-on membrane can also be used to seal moisture inside the RCC, but is not appropriate for all applications.
How Do Additives in Concrete Mix Influence Curing Times? Concrete additives, also known as admixtures, can significantly alter the curing process.
