2503 Enhancing MALP and MKP as Repair Materials Through Joint Usage and in combination with Ceramic Paint

The purpose of this research is to address the corrosion performance of conventional reinforcing steel in uncracked and cracked magnesium-aluminum-liquid-phosphate (MALP) concrete and magnesium-potassium-phosphate (MKP) 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 actively 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. CeramycGuard will be investigated as a possible method to limit the penetration of salt solution into MKP to improve the corrosion resistance provided to reinforcing steels.
