“…MR3 mortar exhibited the lowest value compared with the other mortars, while MR1 mortar exhibited the highest value. The porosity of the MR1 mortar remained high compared with that of the other mortars, which may be explained by its high W/C ratio and These results are in agreement with the findings of other studies on acrylate polymer [15,44,45]. According to the authors, the increase in porosity, particularly for P/C ratios greater than 0.10, was due to the air-entrainment effect of the polymer.…”

“…The application of polymer-layered nanoparticle composites has been recently increased in engineering structures due to the development of beneficial and functional properties like their high strength-to-weight ratio, corrosion resistance, proper thermal insulation, low thermal expansion, etc. [1][2][3][4] Epoxy resins are among the most widely used substances in the production of polymeric composites. [5][6][7] The mechanical and thermal properties of epoxy resins are related to the microstructure and cross-linked network formed during the curing process.…”

In this study, non‐isothermal curing kinetics of the prepared samples was studied using differential scanning calorimetry (DSC) to evaluate the effect of methyl phenyl silicone resin (MPS), acrylonitrile butadiene styrene (ABS), and graphene oxide (GO) on the cure reaction of epoxy resin. Chemical and microscopic structure of prepared nanocomposites was investigated using Fourier‐transform infrared spectrophotometry (FTIR) and scanning electron microscopy (SEM), respectively. Izod impact strength of modified epoxy resin with 5 phr MPS, 2 phr ABS, and 0.1 phr GO was about 53% higher than pure epoxy resin. Evaluation of activation energy (Ea) by Kissinger, Ozawa, FWO and Friedman methods showed that the presence of GO facilitates the curing reaction by reducing Ea about 30% which is due to the catalytic effect of hydroxyl groups presented on the surface of GO for epoxy ring opening. According to Friedman's plots, curing reaction remained autocatalytic for all of samples. The presence of GO increased the autocatalytic term of the reaction (n) from 0.26 to 0.32. Non‐isothermal DSC diagrams obtained from experimental data fitted well with data obtained from theoretical relations.

“…Rubberized mortars have a higher hydrophobic performance than regular mortars without rubber. These characteristics of rubberized mortar can be improved to be better by increasing the quantity of natural rubber colloidal particles added to the mortar matrix 25 . Vo et al, 6 Kong et al, 7 and Muhammad et al 26 studied using natural rubber latex as a film‐forming ingredient in cementitious mortar.…”

Vulcanized natural rubber compound plays an important role to be used as a reinforcement phase for mortar-cement-paste matrix. Natural rubber is an organic binder to increase good adhesion for the flexible-film formation and waterproof membrane within the mortar matrix. Adding sulfur as a curing agent into natural rubber latex can increase chemical bridge bonding within the mortar cement paste matrix. Embedding vulcanized natural rubber 30 wt% (PMC-30) with a sulfur curing system was employed to increase physical, chemical, thermal, and mechanical properties due to interconnective bonding. PMC-30 possessed low water absorption of less than 10%. After 28 days of curing, they possessed a high thermal shock resistance, a low percentage of salt solution absorption, and no thermal deterioration. The mortar composite embedded with the vulcanized natural rubber compound 30 wt% (PMC-30) was an alternative mortar composite formula suitable for use in the seawater, beaches, and salt contact areas due to the lowest percentage of salt solution absorption (1.94%), low water absorption (3.17% ± 0.74), good thermal shock resistance, and the highest flexural strength (6.72 ± 0.39 MPa). Therefore, adding the vulcanized natural rubber compound in mortar cement is a good way to improve the flexural strength and water resistance of mortar cement.
