“…Corresponding bond strength increase is about 19.54%-47.51% when the content of SF increases to 10%. Mirza et al 26 confirmed that mortar including SBR and acrylics showed a better bond strength characteristics. The reason for the increase in bond strength is that the polymer addition decreases the water/cement ratio.…”

“…For M6, namely, with PAE contents of 30% and SF contents of 10%, the weight loss decreases to 4.75%, and the abrasion resistance strength increases to 35.78 h/(kg/m 2 ), which is 54.35% more than M0. The test by Mirza et al 26 showed that after an abrasion-erosion test, the weight loss of SBR-modified cement-based mortars decreased by about 62.26%-71.70%, compared with the control sample without any addition. Sadegzadeh et al 27 have pointed out that abrasion resistance was determined by the pore structure.…”

Experimental investigations on the influence of different amounts of polyacrylic ester and silica fumes on the mechanical properties of mortar such as the compressive strength, splitting tensile strength, bonding strength, and abrasion resistance are presented in this article. The results show that the compressive and splitting tensile strength of mortar can be improved with the addition of polyacrylic ester and silica fumes. Results obtained from both the direct tensile bond test and flexural bond test indicate that the addition of polyacrylic ester and silica fumes improves the bond strength significantly, and the enhancement is more obvious with polyacrylic ester paste as interfacial adhesives. Furthermore, mortar incorporation of polyacrylic ester and silica fumes shows superior abrasion resistance compared to the control mortar. Therefore, the correct combination of polyacrylic ester and silica fumes to produce mortars has been shown to have synergistic effects, which results in excellent properties including high bond strength and superior abrasion resistance. Mortars containing polyacrylic ester and silica fumes are ideal for repairing concrete especially for hydraulic concrete structure.

“…PCMs are also commonly used in civil infrastructures, bridges, external wall insulation mortar, self-leveling mortar, and concrete repaired fields due to their excellent strength, environmental protection, adhesion, waterproofing, resistance to chemical attack, and workability [5][6][7][8]. Additionally, PCM has outstanding performance compared to ordinary mortar as concrete repair materials in case of applying them to deteriorated reinforced concrete structure [9][10][11][12]. However, it is very difficult to choose the appropriate patch repair materials due to insufficient experimental data on the fire resistance and safety of the PCM [12,13].…”

“…To meet fire endurance requirements, the performance of these materials at elevated temperature must be understood based on assessment to the mechanical properties [14]. However, when repair is required, it is very difficult to select the appropriate patch repair materials because of insufficient experimental data on the fire resistance and safety of PCM [7][8][9].…”

Although polymer-modified cement mortar (PCM) has been extensively used as finishing and repairing material, it is necessary to understand its combustion properties and mechanical properties at high temperature. This study evaluated the combustion characteristics with varying experimental parameters such as polymer type, unit polymer content, polymer-cement ratio, and thickness of the specimen. This study also evaluated the compressive strength and elastic modulus of PCMs with focus on the effects of the type of polymer, unit polymer content, and polymer-cement ratio. As a result, the incombustibility of the PCM was in the following order: SBR < VVA < EVA. After heating end, the mass loss rate of the PCM was less than 30%, regardless of the polymer type, unit polymer content, and W/C. In heat release rate test, the higher the unit polymer content, the greater the total heat release, regardless of the difference in W/C. The PAE series showed excellent fire resistance in the temperature range of 200∼400 ∘ C. PCMs with a unit polymer content of 5%, modified with EVA and PAE, showed outstanding compressive strength at 200∼400 ∘ C. At elevated temperature, the modulus of elasticity of PCM declined with an increase in the unit polymer content, regardless of the polymer type.

“…Polymer mortar is similar to conventional cement mortar as it contains fine aggregates, but Portland cement is completely replaced by polymer resin [7][8].When compared to the conventional mortar, polymer mortar exhibits additional advantages such as rapid hardening, improved resistance to chemical attacks and durability along with high mechanical properties [9][10][11][12][13][14]. Performance of polymer mortar depends on various factors such as resin content, types and mixed proportions and method of curing [15][16][17][18].The purpose of present research is to investigate the effect of different methods of curing on mechanical properties of polymer mortar.…”
