“…It could also be seen from Figure 6 that the hardness of sample W was slightly greater than the sample S under the same amount of carbon black. The possible reason was that the crosslinking density of the SMR20 and BR9000 blends was greater than the SMR20 and SBR1502E blends 30 . Comparing with the W and the S in Figure 7, it can be seen that the surface of sample W is smoother than that of S , which further indicates that SMR20 and BR9000 have stronger interaction with fillers and greater hardness.…”

Wear resistance and wet grip resistance are the main properties of tires, but they are often contradictory and difficult to synergize. In this paper, drawing on the bionics concept, the bionic topography of the pits was introduced into the design of the tread rubber structure, and the synergistic improvement mechanism of the tire tread rubber with the bionic pit structures was explored. The overall performance improvement of tread compounds provided a new approach. The research showed that the designed high wear resistance tire tread compounds W2 had the best wear resistance, and the high wet grip resistance tire tread compounds S3 had the best‐wet grip resistance. When the diameter of the bionic unit was 2.5 mm and the pit number was 6, the wear resistance rate of the sample was the highest (about 11.86%), and the wear amount was 70.6; the maximum wet friction coefficient of the sample sliding on the sandpaper surface and the smooth glass surface was 0.834 and 0.71, the corresponding wet grip resistance improvement rates were also 11.89% and 12.34%, respectively. Experiments have proved that the tire tread compounds with the bionic pit structures composed of W2S3 can effectively synergistically improve wet grip resistance and wear resistance.

“…It can be seen from Figure 7 a that the addition of EEUG caused the T c10 of the rubber compound to fluctuate slightly. This is because the internal epoxy group of the EEUG in the rubber compound opened and crosslinked under the action of heat or a coupling agent, thereby affecting the T c10 [ 53 , 54 ]. Both MTES-modified SiO 2 and the addition of EEUG reduced the T c90 and M L of the compound, while the maximum torque ( M H ) and the torque difference ( M H -M L ) increased.…”

“…At the same time, the good compatibility of SiO 2 and the matrix increased the bonding strength between the filler and the matrix. This prevented it from being easily damaged during the friction process, so the abrasion volume was reduced [ 54 ]. Moreover, the better the dispersion of SiO 2 particles, the more difficult the path of crack propagation, the smoother the path of stress transmission to the SiO 2 particles, and the less likely the composite will form cracks on its surface [ 59 , 60 ].…”

A rubber composite was prepared by using methyltriethoxysilane (MTES) to modify silica (SiO2) and epoxidized eucommia ulmoides gum (EEUG) as rubber additives to endow silica with excellent dispersion and interfacial compatibility under the action of processing shear. The results showed that compared with the unmodified silica-reinforced rubber composite (SiO2/EUG/SBR), the bound rubber content of MTES-SiO2/EEUG/EUG/SBR was increased by 184%, and its tensile strength, modulus at 100% strain, modulus at 300% strain, and tear strength increased by 42.1%, 88.5%, 130.8%, and 39.9%, respectively. The Akron abrasion volume of the MTES-SiO2/EEUG/EUG/SBR composite decreased by 50.9%, and the wet friction coefficient increased by 43.2%. The wear resistance and wet skid resistance of the rubber composite were significantly improved.

“…The main components waste tire aggregate consists of are the natural and synthetic rubber (also known as a polymer). The styrene-butadiene in the synthetic rubber ratio influences the properties of the polymer: with high styrene content, the rubbers are harder and less rubbery, and takes a longer time to dissolve under normal conditions, which leads to a rise in environmental concern when it ends life service [ 17 , 18 , 19 , 20 , 21 ]. Currently, the worldwide growth of the automobile industry and the increase in car use have tremendously boosted tire production.…”

Systematic Experimental Assessment of POFA Concrete Incorporating Waste Tire Rubber Aggregate

et al. 2022

Several researchers devoted considerable efforts to partially replace natural aggregates in concrete with recycled materials such as recycled tire rubber. However, this often led to a significant reduction in the compressive strength of rubberized concrete due to the weaker interfacial transition zone between the cementitious matrix and rubber particles and the softness of rubber granules. Thereafter, significant research has explored the effects of supplementary cementitious materials such as zeolite, fly ash, silica fume, and slag used as partial replacement for cement on rubberized concrete properties. In this study, systematic experimental work was carried out to assess the mechanical properties of palm oil fuel ash (POFA)-based concrete incorporating tire rubber aggregates (TRAs) using the response surface methodology (RSM). Based on the findings, reasonable compressive, flexure, and tensile strengths were recorded or up to 10% replacement of sand with recycled tire fibre and fine TRAs. In particular, the reduction in compressive, tensile, and flexural strengths of POFA concrete incorporating fibre rubber decreased by 16.3%, 9.8%, and 10.1% at 365 days compared to normal concrete without POFA and rubber. It can be concluded that utilization of a combination of POFA and fine or fibre rubber could act as a beneficial strategy to solve the weakness of current rubberized concrete’s strength as well as to tackle the environmental issues of the enormous stockpiles of waste tires worldwide.
