Field Concrete Testing - San Diego

What it is: Testing freshly mixed concrete at construction sites is required per code which includes sampling the concrete from the truck. This field testing procedure checks for temperature, slump, and we cast a set of cylinders for compressive strength verification.

What it does: Slump is a field test to measure water quantity which is mixed within the sand, rock and cement. This is mainly for field-use measurement as a guide for the work-ability of concrete. The concrete temperature is checked and compared to a specified degree range as stated in the ACI 318 code book. Casting a set of freshly mixed concrete cylinders for compressive strength testing. This testing procedure is required to be reported to the design engineer. The compressive strength test results (psi) pounds per square inch are verified per design engineer plan requirements. This can range from 3000 to 8000 psi depending on the structural location and application.

What we do: In the field, we test the freshly mixed concrete for temperature, slump and cylinder samples for compressive strength.

Concrete is tested in the plastic state for slump, air content and unit weight. In addition, test cylinders and beams can be cast to determine compressive and flexural strength.
