Hydration - What Does Hydration Mean in Construction?

WebConcrete continues to cure for long amounts of time, however after 28 days; the normal mixture of concrete will achieve approximately 95% of its overall strength. The act of hydration is the reason that when concrete is placed under water, it becomes hard and strong and will continue to harden, the longer the concrete remains in the water. WebCuring of concrete is a method of keeping fresh concrete in a moist and warm condition enough so that the hydration of cement can continue. The curing of concrete will increase its strength and decrease its permeability of concrete. It is also helped in limiting thermal and plastic cracks, which can severely impact the durability of structures.
