Cement-Based Composites: Manufacturing and Properties

Experimental and theoretical research is conducted in order to study constitutive response of construction materials using mechanics of composite materials. The interrelationship of early age properties such as manufacturing technique used, initial material properties such as stiffness, bond, rheology, and mechanical properties are related to performance and long term characteristics.  New techniques such as closed loop strain controlled testing and digital image analysis techniques are developed for automated determination of crack density, crack spacing and damage evolution under loads.  A high-speed impact test set up was also developed for high speed testing and characterization of composite response under impact loads.
