How does cement work?

Answer 1

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.

Portland cement is a generic term for nearly all modern cement. It owes both name and origin to a British stone mason named Joseph Aspdin. In the 1820s, Aspdin’s quest for a manufactured counterpart to natural or Roman cement (derived from volcanic ash and other naturally occurring minerals) led to his discovery and patent of portland cement. Aspdin’s name for his invention served two purposes. It distinguished the material from Roman cement, which existed for centuries. It also was a marketing ploy. Concrete made from his new cement resembled a highly prized building stone quarried on the Isle of Portland.
