“…The SME-PS protectant was applied by immerging the samples in the SME-PS blend for 6 h (dosage 1) and 24 h (dosage 2) ( 51 ). Moreover, the performance of concrete sealers—including polyurea, epoxy, long-chain/fluorinated silane, ACM&HG (spray coating for polyurea while brush coating for all the other sealers with a dosage of 4 m 2 /kg) ( 33 ), linseed oil, silane, siloxane (one-time brush coating with a dosage of 3.07 m 2 /L) ( 76 ), acrylate-copolymer-/acrylic-latex-modified cementitious coating (a controlled thickness of 3–5 mm) ( 126 ), and 40% silane-based water repellent (two-time brush coating with an interval of 6 h and a dosage of 6.9 m 2 /L) ( 127 )—in improving F/T durability of concrete samples is compared with that of SME-5%PS. Although bacteria have been used in repairing systems to improve the F/T resistance of concrete pavement ( 128 ) and used as surface deposition to improve the F/T resistance of limestone ( 129 ), there are few studies investigating the influence of biotic sealers on concrete.…”

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.

“…Kompozytowe materiały cementowe KSB/cement znalazły szerokie zastosowanie w naprawach dróg i mostów (8,(13)(14)(15). Jednakże, podobnie jak w przypadku innych polimerów (16)(17)(18), dodatek KSB znacznie opóźnia proces hydratacji cementu.…”

“…In addition, the carbonation resistance, chloride ions permeability resistance and durability are improved as well (2,(10)(11)(12). SB/cement composite cementitious materials have been widely used in roads and bridges repairs (8,(13)(14)(15). However, similar to other polymers (16)(17)(18), the hydration process of cement is signifi cantly retarded in the addition of SB.…”

Styrene-butadiene copolymer [SB] modified cement-based materials are widely used, but the addition of SB can delay the setting and hardening of cement, which limits its application in some projects. In this paper, nanosilica was selected as the modifying component to study its influence on the early hydration, setting and hardening of SB/cement composite material. By measuring the setting time and early strength of nanosilica modified SB/cement composite material, the influence of nanosilica on the setting and hardening process of composite cementitious material was analyzed. The hydration heat of nanosilica modified SB/cement composite material was determined by isothermal calorimetry, and its hydration products were examined by X-ray diffraction, so as to analyze the influence of nanosilica on the early hydration process of composite cementitious material. The results show that the addition of nanosilica can effectively promote the setting and hardening process of composite cementitious material, and the higher the dosage is, the more significant the effect is. It also indicates that addition of nanosilica accelerates the formation of ettringite and calcium hydroxide, by promoting the hydration of tricalcium aluminate and tricalcium silicate. Shortens the hydration induction period and acceleration period of the composite cementitious material and accelerates the hydration process, thereby shortening the setting time and increasing the early strength.

“…Recently, several polymers that are soluble in water and polymeric particles that are distributed in water (latexes) have been introduced in mortars and to concretes increase their fluidity (Anagnostopoulos and Dimitriadi, 2021). One of the best performance was achieved by "C6"(an acrylic-modified cementations coating compound), which was sprayed to a corroded highway wayside barrier in Xinjiang as part of a project to safeguard it, and three years of monitoring revealed that the coating functioned well in the field without visible delamination or cracking (Guo et al, 2017). In another study, polymer has been successfully employed to improve the properties of concrete mixtures (Aggarwa et al, 2007).…”

In general, injecting grouts into small fractures, cavities, porous soil media, areas of water leakage, fixing cracks or defects in concrete, and filling spaces beneath metal bases or digging anchors are widely applied because of the great strength and workability of the cement in these materials. Furthermore, grout is employed effectively in the manufacturing semi-flexible pavement mixes. The goal of this research is to develop a polymer modified grout that can be used as a flowable grout for semi-flexible pavement mixes. The grout combination was made up of Ordinary Portland Cement (OPC), Acrylic emulsion (ACR), superplasticizer (SP), and water. ACR doses were 0.25, 0.5, 0.75, and 1.0 as a percent of OPC content. Flowability, compressive strength, and flexural strength tests were conducted to characterize the produced grout, with different amounts of the specified components being employed for each test. The results revealed that the flow time rises slightly as the ACR increases. It is also shown that there is an ideal ACR dose based on the compression strength. Where in most cases, the upgrading of the produced grouts was validated by a flexural strength test. As a conclusion, polymer modified grout worthily adds acceptable features to grout mechanical characteristics if the constituents of the grout are optimized.
