“…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. PMC‐0 as a reference specimen had an average flexural strength of 4.27 MPa.…”

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.

“…To do this, traditional additives like cement, lime, and y ash were often used to improve the stiffness and strength of the expansive subgrade [18,19]. Although chemical additives are more useful in the stabilisation of frustrating soil because they help the physical and mechanical qualities of soil, such as its resilience, deformability, strength, and stability, they are heavily exploited, especially for expansive soils [17,20,21]. Despite the considerable energy consumption involved in producing these materials, despite their usefulness, there are environmental issues [21,22].…”

“…On the other hand, there is another type of stabilisation called non-traditional additions. Non-traditional additions have lately been embraced, and their lives can alter the microstructure of pavement components to improve the bene cial properties and durability of expanding soil [15,25,26], Enzymes, acids, salts, resins, naturally occurring resins, and biopolymers are examples of non-traditional additives [20,27]. Numerous of these materials are either manufactured naturally or have a natural occurrence.…”

Soil stabilization is the optimal approach that can improve various soil properties, including permeability, compressibility, strength, and durability. It is widely known that chemical stabilization can improve the mechanical characteristics of problematic soils. This work examined sodium alginate (SA) as a sustainable bentonite clay stabiliser to improve a high-plasticity clay. We soaked sodium alginate at different concentrations (0%, 0.5%, 1%, 1.5%, 2%, and 3%) to stabilise the bentonite clay of the compacted soil samples, utilising techniques such as standard proctor and unconfined compressive strength (UCS), scanning electron microscopy (SEM) coupled with energy-dispersive spectroscopy (EDS), and X-ray diffraction (XRD). Adding sodium alginate in different amounts (0.5%, 1%, 1.5%, and 2%) lowered the optimum moisture content (OMC) and raised the maximum dry density (MDD). Following 0, 14, and 28 days of curing, the UCS of stabilized samples were evaluated. It was found that adding 2% sodium alginate to bentonite clay raised both the maximum dry density and the optimum moisture content. The soil stabilized using the soaking technique displayed a higher 14-day UCS at the ideal sodium alginate content of 2% compared to the untreated soil. The microstructural investigation showed that the increase in strength was due to sodium aluminosilicate hydrate, a new cementitious material that filled in the pores and made the bonds between particles stronger. This research's conclusions will support bentonite clay's stability through the use of environmentally acceptable sodium alginate in subgrade applications.

“…In recent years, the incorporation of polymeric materials has been an important topic in the context of conventional fiber reinforcement. Styrene-butadiene rubber (SBR) and natural rubber latex (NL) have been widely used to improve the physical, mechanical, and Polymers 2022, 14, 320 2 of 19 durability properties of cement materials [11][12][13][14][15][16]. The usage of NL for cement paste, mortar, and concrete has significantly increased [17][18][19][20][21].…”

Dielectric and Mechanical Properties of CTAB-Modified Natural Rubber Latex–Cement Composites

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.
