The Concrete Laboratory

The Buzzi Unicem USA Concrete Lab is located in Greencastle, IN on property where the cement plant is located. The Concrete Lab now serves as a replacement facility for a Technical Center that was shut down in Houston in the early 1990’s. The Lab serves a support function for the rest of the Company to perform testing requests from both Manufacturing and Sales. Lab personnel are ACI Field Certified, and the Lab is certified by the CCRL on each inspection tour. A wide range of cement and concrete testing is available including compressive and flexural strength of concrete, freeze-thaw, deicer scaling, sulfate resistance, and rapid permeability testing. The Lab can perform instrumental specific gravity, and particle sizing of cements and raw materials.

A walk-in environmental chamber is available for testing concrete at elevated or reduced temperatures and varying humidity, and is also used for concrete drying shrinkage testing. The Concrete Lab serves as the Reference Center for slag testing and distribution of slag reference cement to State DOT’s and customers who request it.

The Lab frequently does grinding, sieving, and blending projects for various plants, and helps with compliance testing for various ASTM standards for concrete, cement, and specialty cement products.
