Project description

The purpose and goals of this research is to address the corrosion performance of conventional reinforcing steel in uncracked and cracked Magnesuim-Alumino-Liquid-Phosphate-Based (MALP) concrete in simulated repairs of Portland cement of both high and low quality. Reinforcing bars will be evaluated in both a clean and passive state and in an activity corroding state. The project will evaluate the ability of MALP concrete to withstand freeze-thaw cycles both as an individual material and in conjunction with Portland cement concrete.
