Quality Tests on Fresh Concrete. Most Common Quality Tests on Fresh concrete are: 1. Workability Tests. Workability of concrete mixture is measured by, Vee-bee consistometer test, Compaction factor Test, and Slump test. Read More: Vee-bee consistometer test , Compaction factor test, Slump test. 2. Lab Location: 122 Colton Hall Lab PIs: Stephen George and Nasser Channaoui. High Performance Concrete Laboratory. With funding from the National Science Foundation, the High Performance Concrete Laboratory in the Civil and Environmental Engineering Department is the only academic facility capable of testing very high strength concretes under uniaxial as well as triaxial states of stress.We perform fresh tests in the field to determine concrete slump, air content, unit weight, and temperature for compliance with project requirements. Cylinder, beam, prism, and cube specimens of cementitious materials are cast in the field and transported to the laboratory for strength testing.

Laboratory concrete tests ultimately confirmed this hypothesis. • Modified foam drainage tests (FDT) further indicated that in presence of cement, foams derived of synthetic AEAs were significantly less stable than those of NVR. Correlation of the FDT and concrete tests suggests that the FDT can be used to evaluate performance of AEAs used inOur laboratory staff is accredited and capable of conducting some of the latest test methods including all tests related to self-consolidating concrete (SCC) and ultra-high-performance concrete (UHPC), in addition to the conventional commercial services.
