Effect of polymer to cement ratio on seawater corrosion resistance of polymer modified cementitious coatings

Coating protection is one of the simplest and most effective measures to protect concrete. Effect of polymer to cement ratio (p/c) on seawater corrosion resistance of polymer modified cementitious coatings (PMCC) is investigated base on bond strength, tensile strength, elongation at break and flexural strength tests. The results show that optimal p/c is 0.6. After seawater corrosion, retention rate of bond strength, tensile strength, elongation at break and flexural strength reach 88.44%, 82.74%, 90.56% and 98.6%, respectively.
