“…Compared with the concrete samples treated with organic, inorganic, and hybrid sealers, the samples treated with SME-5%PS demonstrate superior F/T durability even without air entrainment. Since the significance of air entrainment is greater than that of concrete sealer to the F/T durability of concrete (130), such results confirm the advantage of using SME-PS to protect concrete from F/T deterioration. However, the influence of application dosage of SME-PS protectant on its protecting performance on concrete F/T durability is not fully understood and relevant future research is needed.…”

Freeze–thaw cycles, application of deicing salts, and rebar corrosion are becoming main sources of concrete deterioration in bridge decks and pavements. During the past few decades, concrete surface treatments have begun to receive wide acceptance because of their effectiveness in sealing the concrete. Surface treatments achieve this by limiting fluid ingress, thereby reducing damage associated with freeze–thaw cycles, deicing salt application, and rebar corrosion. Soy methyl ester-polystyrene blends (SME-PS) have been shown to be an innovative, promising method of topical sealing. SME-PS, which is a derivative of soybean oil and expanded polystyrene, has been continuously studied since 2008. In this context, a comprehensive literature review compared the performance of SME-PS with that of traditional concrete sealers, including organic, inorganic, hybrid, and biotic sealers. These sealers were reviewed for performance in reducing water absorption and chloride penetration and improving freeze–thaw durability of concrete. The reviewed papers indicate that SME-PS possesses superior performance as a concrete protectant for reducing water absorption, chloride penetration, and freeze–thaw damage. To further enhance the feasibility of SME-PS, future studies may include investigating the physical and chemical protecting mechanisms of SME-PS, understanding the factors that affect the penetration behavior of SME-PS in concrete, and evaluating the short and long-term effectiveness of SME-PS in concrete.

“…Some systems may work via double mechanisms having dual-component products in their composition. A decrease in water ingress improves concrete's resistance to freeze-thaw cycles [7] and alkali-aggregate reactions [39]. Porter [27] reported that the surface scaling due to freezing and thawing greatly decreases when sealers or coatings are used on concrete surfaces.…”

“…Concrete structures globally undergo different forms of attack from environmental influences such as wetting and drying, freezing and thawing, and extreme temperature changes [5][6][7][8][9]. Many environmental attacks become more severe for concrete in the presence of chloride and sulfate ions sourced from anti-icing or de-icing salts and seawater/soil, respectively [10][11][12][13][14].…”

Concrete structures undergo different forms of damage during their service life. The aim of this study is to identify the most common forms of concrete damage in field conditions. A number of concrete elements and structures were visually inspected and the damage was photographed. The damage phenomena covered are delamination, popout, spalling, scaling, drying shrinkage cracking, corrosion-induced cracking, map cracking, rust and salt stains, discoloration, and mold and moss growths. The probable reasons for these damage phenomena are discussed in this study. Moreover, this study highlights how concrete structures can be protected from the aforementioned forms of damage by using sealer and coating systems as surface treatments. Different sealer and coating systems, emphasizing their selection for specific uses, installation on concrete substrate, effects on concrete durability, performance criteria, and performance evaluation methods have been discussed. Furthermore, some recommendations are given to improve the performance of concrete sealer and coating systems for the protection of concrete structures in field conditions.

“…The surface coatings are used on concrete surfaces aesthetically important and highly exposed to public view. They are generally concrete can improve its freeze-thaw durability (Li et al 2012;Litvan 1992) and resistance to alkali-aggregate reactions (Filice, Wong 2001). Almusallam et al (2003) and Moon et al (2007) observed that surface coatings substantially improved the freeze-thaw resistance of concrete due to reduced water absorption.…”

Abstract. This paper reports the water vapor transmission and waterproofing performance of a silane-based penetrating sealer (PS), two cementitious coatings (CC1 and CC2), and a polymeric coating (PC). The sealer and coating products were applied on 100-mm concrete cubes. In total, fifteen concrete cubes including the control specimens were prepared.The treated concrete cubes were tested to determine the ability of the selected products to improve waterproofing and to transmit water vapor. The correlation between water vapor transmission and waterproofing performance was also examined. Experimental results revealed that the cementitious coating CC2 had the lowest degree of water vapor transmission but the highest degree of waterproofing performance. In contrast, the highest degree of water vapor transmission but the lowest degree of waterproofing performance were observed for the cementitious coating CC1. The penetrating sealer PS provided greater water vapor transmission but lower waterproofing ability than the polymeric coating PC and the cementitious coating CC2. The best-performing coating with regard to water vapor transmission and waterproofing was the polymeric coating PC. Furthermore, the water vapor transmission and waterproofing performance of the sealer and coating systems were strongly correlated; this suggests that one of these two properties can be predicted by testing the other.
