Effect of polymer modified cementitious coatings on water and chloride permeability in concrete

Long-term performance of concrete surface coatings in soil exposure of marine environments

“…High breathability allows the water vapor to exit concrete, therefore reducing the risk of high pressures at concrete and coating interface. Such high pressures at interface may result in coating delamination and/or cracking [5]. These technical superiorities of CPE coating are reflected in lower chloride concentrations compared to the CPD.…”

“…It was observed that the chloride ion penetration of uncoated specimens was 20-40% higher than the coated ones. Diamanti et al [5] investigated the effect of polymer modified cementitious coatings on water and chloride ion permeability of concrete. Authors reported that investigated coatings effectively hindered the chloride ion diffusion by decreasing the chloride diffusion coefficient of concrete mixture with w/cm of 0.65 from 8.0 Â 10 À6 to 0.2 Â 10 À6 mm 2 /s.…”

“…Impermeability against water, thermal stability, adequate adhesion, crack-bridging ability, and adequate elasticity are known as the main characteristics of a coating to create a barrier on the surface of concrete [4]. This technique is applicable for the new construction and repair of the existing damaged elements [5]. http Zhang et al [6] studied the performance of geopolymers as protecting coatings for concrete exposed to marine environments.…”

The study of an energy efficient cool white roof coating based on styrene acrylate copolymer and cement for waterproofing purpose—Part II: Mechanical and water impermeability properties

“…Although polymer-modified cement-based waterproof coatings have been extensively investigated in China [2][3][4][5][6][7][8][9], to the best of our knowledge, only a few scientific papers and books to date are related to this topic [10][11][12][13][14]. These studies simply focus on the application performances of the polymer-modified cement-based waterproof coatings.…”

The investigation of factors affecting the water impermeability of inorganic sodium silicate-based concrete sealers

“…The ingress of water and water-soluble aggressive agents (e.g., chloride ions, carbon dioxide, sulfur dioxide and sulfates) into concrete objects results in reinforcement corrosion and consequently the deterioration of the reinforced concrete structures [1][2][3][4][5][6], which has become a worldwide problem in the past few decades. Considerable resources are required to repair and rehabilitate the deteriorated structures, and the cost of repair is sometimes even higher than the original investment [7][8][9][10].…”
