How does cement dry up?
When water is added it starts a process beginning with the formation of short hexagonal crystals. it is this process of crystal formation which begins the setting process and usually is substantially complete after 24 hours. However, the crystals continue to form and fill up the spaces for weeks and even months as long as the cement is not allowed to dry out. When mixing cement it is recommended to keep it wet for at least 3 days, when it reaches maybe 80% of its final strength, but a week to ten days is better. Cement will continue to harden for several years. The strongest cement you can get is that which sets up underwater and is never allowed to dry out

What is a 'dry polymer'?
A dry polymer is one that is not in solution. they are used where moisture would create an issue. Sometimes dry polymer powder is added to cement so that when the cement is hydrated to make concrete, the dry polymer is hydrated at the same time. If a wet polymer, or polymer solution were used, it would react with the cement and make it unusable.
