Research Infrastructure

World-class research tools, techniques and expertise

     We apply modern cement chemistry methodologies that are rooted in material science, geochemistry, civil engineering, architectural engineering, applied statistics, and computer science. The main lab is outfitted as a state-of-the-art laboratory with fume hoods, deionized water systems, temperature-controlled heat blocks, mixing plates, standard ovens, and pH/ion selective electrodes. The laboratory is unique as it houses bespoke environmental chambers with atmosphere controls to simulate in-service applications of cementitious materials. In addition, the laboratory is outfitted with TA instrument’s cutting-edge TAM Air 8-channel Isothermal Calorimeter and an HR-20 Rheometer for characterization of fresh-state properties of materials. Moreover, the laboratory has advanced multi-channel potentiostats for the characterization of degradation phenomena. All instruments are equipped with in-situ characterization capabilities. Lastly, we are affiliated with the Materials Research Institute at PennState, where we utilize advanced characterization techniques to further understand our materials work.
