How It Works Concrete Popular Mechanics

Oct 01, 2009How it's made and how you use it. An average 123 mix contains one part cement, two parts sand and three parts gravel. To make 1 cubic yard of concrete, you'd need seven 94-pound bags of cement, about 1/2 cubic yard of sand and just over 3/4 cubic yard of gravel. The amount of water you use depends on how wet the sand is.

FAQs Cement Australia

Concrete is basically a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and Portland cement. Portland cement is not a brand name, but the generic term for the type of cement used in virtually all concrete. Cement comprises from 10 to 15 percent of the concrete mix, by volume.
