Sets the standard for concrete and aggregate testing. Testing of concrete and aggregate provides engineers and contractors with vital information about the composition and performance of the concrete they will be using.

What Are Aggregate and Concrete?

Simple concrete is composed of water, aggregate and cement. Additional additives can be used to cause the concrete to dry faster, improve strength, change the color or improve water resistance. Aggregate can be sand, gravel or some other stone. Cement forms crystals as it dries, binding together the aggregate to form a solid mass.

Why Test?

The composition of concrete varies from batch to batch as well as between manufacturers. A concrete and aggregate testing facility ensures that all concrete used in a construction is consistent and meets current standards. Testing also guarantees that the concrete ordered by the contractor is consistent with the project’s needs.

Types of Testing

Concrete and aggregate inspection involves both onsite and laboratory testing. Qualified laboratories will take samples of mix components from the manufacturer and samples of the mixed product before and after it is delivered. Tests include strength, curing speed, type and quality of additives, composition and amount of entrained air.
