“…Furthermore, the average flexural strength of mortar composites combined with vulcanized natural rubber compound increased progressively when the amount of vulcanized natural rubber compound increased from low to high as shown in Figure 9. Yaowarat et al indicated adding natural rubber latex into concrete effect to increase the highest flexural strength (4.2 MPa) but decrease compressive strength 67 . In addition, Buritatun et al 68 and Sukmak et al 69 reported natural rubber latex can reinforce the bridge bonding of the soil particles effect to modify the compressive and flexural strengths and durability of concrete pavements.…”

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.

Flexural strength of concrete is an important property, especially for pavements. Concrete with higher flexural strength has fewer cracking and durability issues. Researchers use different materials, including fibers, polymers, and admixtures, to increase the flexural strength of concrete. silicon carbide and tungsten carbide are some of the hardest materials on earth. In this research, the mechanical properties of carbide concrete composites were investigated. The silicon carbide and tungsten carbide at different percentages (1%, 2%, 3%, and 4%) by weight of cement along with hybrid silicon carbide and tungsten carbide (2% and 4%) were used to produce eleven mixes of concrete composites. The mechanical tests, including a compressive strength test and flexural strength test, along with the rapid chloride permeability test (RCPT), were conducted. It was concluded that mechanical properties were enhanced by increasing the percentages of both individual and hybrid carbides. The compressive strength was increased by 17% using 4% tungsten carbide, while flexural strength was increased by 39% at 4% tungsten carbide. The significant effect of carbides on flexural strength was also corroborated by ANOVA analysis. The improvement in flexural strength makes both carbides desirable for use in concrete pavement. Additionally, the permeability, the leading cause of durability issues, was reduced considerably by using tungsten carbide. It was concluded that both carbides provide promising results by enhancing the mechanical properties of concrete and are compatible with concrete to produce composites.

The usage of NL for cement paste, mortar, and concrete has significantly increased [17][18][19][20][21]. NL is classified as an environmentally friendly polymer elastomer latex material, which can be widely used to enhance the tensile properties of cement materials owing to its excellent flexibility, ductility, and toughness properties [18,[22][23][24][25][26][27][28][29].…”

Cetyl trimethyl ammonium bromide (CTAB)-modified natural rubber latex/Portland cement paste (CTAB + NL/PC) composites were fabricated by varying the NL/cement and CTAB/cement ratios to improve the elastic property of PC. The stability and workability of the CTAB-modified NL particles in the PC matrix were significantly improved. The microstructure and dielectric property analyses of PC, CTAB/PC, NL/PC, and (CTAB + NL)/PC composites were performed to describe the interaction mechanism between the CTAB-modified NL and PC. The portlandite phase in PC was reduced by incorporating CTAB + NL. Although the tensile strength of NL/PC was significantly increased, its compressive strength also greatly decreased by ~40.3%. The tensile and compressive strengths of CTAB/PC were not significantly improved. Notably, the tensile strength of (CTAB + NL)/PC was significantly increased compared to those of PC, CTAB/PC, and NL/PC, while the depreciated compressive strength was only 18.7%. The optimized compressive–tensile performance of (CTAB + NL)/PC was equal to that of PC. The dielectric constants of NL/PC, CTAB/PC, and (CTAB + NL)/PC were reduced due to the low dielectric constant of NL and the ability of CTAB to capture negative charges in the PC matrix, leading to a reduction in the negative surface charges and hence the interfacial polarization. This result was confirmed by the decreased loss tangent in a low-frequency range, which is usually reduced by decreasing the free charges. This work provides a comprehensive guideline for significantly improving the elastic property of PC while retaining a high compressive strength.
