resistance of concrete to crushing


Properties of concrete Wikipedia

Concrete tests can measure the "plastic" (unhydrated) properties of concrete prior to, and during placement. As these properties affect the hardened compressive strength and durability of concrete (resistance to freezethaw), the properties of workability (slump/flow), temperature, density and age are monitored to ensure the production and placement of 'quality' concrete.

resistance of concrete to crushing

Concrete, usually Portland cement concrete, is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently a limebased cement binder, such as Portland cement, but sometimes with other hydraulic cements, such as a calcium aluminate cement.
