Dear Customers: Concrete and Cement are NOT the same !

Dear Customers: Concrete and Cement are NOT the same !

Concrete is a mixture of 60 – 65% aggregates like sand, gravel, and crushed stone, 15 – 20% water, and only 10 – 15% cement. When mixed, the cement and water harden, binding the aggregates into the solid mass we call concrete. So, there is no such thing as a cement sidewalk!

Here’s one of the main reasons cement and concrete are so often confused: There is cement in concrete. When cement is blended with water, it creates a paste. And when that paste is combined with aggregates like gravel and sand, the result is what we know and love as concrete. Cement itself is made from calcium and silica-rich materials, such as limestone and clay. Its unique adhesive properties make it an excellent binding agent, but on its own, cement is prone to cracking. Compared with concrete, which can last hundreds of years, cement is much less durable. To use an analogy, cement is to concrete as milk is to ice cream. Sure, ice cream has milk in it, but it isn’t milk. It’s actually much better.
