What is Concrete and what are the Properties of Concrete ...

Sep 30, 2013  Concrete is a mixture of portland cement, water, aggregates, and in some cases, admixtures. The cement and water form a paste that hardens and bonds the aggregates together. Concrete is often looked upon as “man made rock”. Concrete is the most widely used construction material in the world.

Properties of concrete - worldstudybible

Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. Tests can be made to ensure the properties of concrete correspond to specifications for the application.
