Cement and Pozzolans Laboratory

The Concrete and Materials Branch (CMB) has the capabilities to conduct analysis of the performance of cements and pozzolans in a full service materials laboratory. Any cement type can be analyzed, and testing of pozzolanic materials such as Granlated Blast-Furnace Slag (GGBFS), Metakaolin, Coal Ashes (Type C & F), Silica Fume and mineral admixtures such as limestone additions can be performed. The lab is equipped to perform complete chemical and physical tests, including ASTM C150 and ASTM C618, to evaluate quality assurance testing of existing sources. Some of physical requirements tests performed are for fineness, air content, false set, soundness, density, setting time and compressive strength. Additional tests can be run for heat of hydration (calorimetry) and expansion. Tests can be performed in accordance with standard ASTM methods or modified to meet specific needs. Accurate and unbiased test results are provided to the customer.
