“…The ratio of the axial compressive strengths and cube compressive strengths of different kinds of concrete was different, and the ratio of the two was between 0.69 and about 0.83 in this test. Based on the measured values of the axial compressive strength and cube compressive strength, a new calculation relationship suitable for SSFRC was fitted [44][45][46], as shown in Equation (1), and the relationship between the two is shown in Figure 6: In Table 5, the compressive strength of the cube is the compressive strength value obtained by testing a cube with a size of 100 × 100 × 100 mm. This value is mainly used to determine the strength grade of the concrete.…”

“…With the rapid development of the global transportation industry, hundreds of millions of discarded tires are produced by the elimination of vehicles every year [1,2]. According to statistics, about 50 million tires are directly discarded every year, with only a small portion able to be recycled, and 500 million tires will be discarded by 2030 [3,4].…”

Recycled rubber (RR) and recycled spiral steel fiber (RSSF) were added to plain concrete (PC) to prepare recycled spiral steel fiber rubber concrete (SSFRC) with matrix strengths of C30, C40, and C50. Strength tests on the PC, rubber concrete (RC), and SSFRC were carried out, including the cube compressive strength, splitting tensile strength, and flexural strength. The effects of RSSF and RR on the mechanical properties of concrete were analyzed. Simultaneously, the stress–strain curve of the SSFRC was obtained through axial compressive testing, and the toughness of SSFRC was evaluated by three indexes: the tensile compression ratio, bending compression ratio, and toughness index. The results show that adding RR to PC results in a decrease in the mechanical properties of concrete with different matrix strengths, and the addition of RSSF can make up for the strength loss of the rubber. The mechanical strength of SSFRC with different matrix strengths increased first and then decreased with the increase in RSSF content. The cubic compressive strength reached its peak value when the content of RSSF was 1%, and the splitting tensile strength and flexural strength reach their peak values when the content of RSSF was 1.5%. RSSF works best with rubber particles at the right dosage to further increase the toughness of the concrete. When the rubber content is 10%, and the RSSF content is 1.5%, the mechanical strength enhancement effect of SSFRC is at its best, and the toughness is also at its best.

“…In view of this potential, the hydroprocessing of TPO has been studied by several researchers by feeding it either pure − or mixed with other streams. ,, Table summarizes some of the works conducted in the field. Herein, it is important to highlight the important contributions of Hita et al , and Palos et al, also from the University of the Basque Country.…”

Pursuing the End-of-Life Tire Circularity: An Outlook toward the Production of Secondary Raw Materials from Tire Pyrolysis Oil

Pyrolysis is perceived as the missing link between the management of end-of-life tires (ELTs) and the tire industry because it strikes directly in the transition from a linear to a circular economy model and toward the defossilization of diverse economic sectors. Tire pyrolysis oil (TPO) is one of the most valuable and interesting fractions derived from the pyrolysis of ELTs. It contains valuable chemicals including, among others, benzene, toluene, ethylbenzene, and xylene, as well as limonene, which are some of the building blocks of the petrochemical industry. Within the circular economy framework, traditional practices such as the direct use of TPO in combustion systems seem to exhibit a low circularity degree. Instead, the production of secondary raw materials that can be reused for multiple purposes associated with the petrochemical industry is getting special attention. Based on the above, this work aims at reviewing different pathways currently explored in the scientific community to produce various value-added products from TPO. Due to the similarity of its properties with those of petroleum streams, the coprocessing of TPO using existing units in conventional refineries exhibits a massive potential. In this manner, the properties of the derived products can be fine-tuned according to the hydrocarbons and petrochemical market requirements. As such, discussed are the advantages, recent progress, and challenges in the implementation of conventional refinery practices such as distillation, fluid catalytic cracking (FCC), hydroprocessing, and steam cracking for TPO post-treatment. These processes are seen as the path to integrate TPO in the current hydrocarbon/petrochemical market.

“…It was possible to encounter studies where pyrolytic oil was used at very high fractions 20 or even in pure form. 21 Straka et al 22 reported that pyrolysis oil could be used as a component of a gasoline pool after various chemical treatments, as jet fuel, as diesel, and as a low-sulfur fuel oil component in marine transportation. Reviewing the use of pyrolytic fuels, Yaqoob et al 23 determined the optimum pyrolytic fuel ratio as 10% for pyrolytic oil–diesel blends.…”
