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.
