Properties Of Cement Stone

A Portland Stone is a yellow limestone from the Isle of Portland, in Great Britain. Historically, cement can be traced back to the early Roman Empire, and contributed to the building of the great structures of the Roman Empire. By varying the amounts and types of the same basic ingredients, cement with various properties may be obtained.
