“…Chloride ions infiltrate into the inner section of conventional and RuC concrete when immersed in NaCl solution and react with the cement hydration product (C 3 A), resulting in a loss of compressive strength. 11 A similar result pattern is received in the previous research. 11,13,[47][48][49][50] It is found that after immersion in a saline atmosphere of chloride salt, the loss in RuC compressive strength is less than the conventional concrete, which indicates that adding CR into concrete can increase the concrete's resistance to chloride salt.…”

“…RuC's mechanical characteristics improved as rubber particle size increased from 1-3 mm to 3-6 mm but decreased when rubber content increased. 11 Compared to self-consolidating concrete containing metakaolin, 15% zeolite as pozzolanic material improved resistance to penetration of chloride ions and MgSO 4 attack in concrete. 12,13 The high MgSO 4 concentration in the hydration products increases the quantity of gypsum, and the excess gypsum produces high expansion, which increases the size and quantity of pores, lowering compressive strength.…”

Limited investigations are available on the influence of chloride and sulfate solutions on pozzolana‐based cement rubberized concrete after crumb rubber treatment. Mechanical and durability characteristics of rubberized concrete are assessed and compared to conventional concrete. Five contents of crumb rubber (10%–30% at 5% of increment) are utilized for partially replacing fine aggregate in concrete. The optimum amount of crumb rubber in concrete is revealed at a replacement level of 15%. The specimens remained in the crystalline form after being immersed in NaCl (sodium chloride), Na2SO4 (sodium sulfate), and MgSO4 (magnesium sulfate) solution, according to structural analyses by XRD (X‐ray diffraction). When rubberized concrete is submerged in both sulfate solutions with the same concentrations and for the same amount of time, the specimens immersed in Na2SO4 solution lose less weight and compressive strength than specimens submerged in MgSO4 solution. The losses in compressive strength of conventional concrete are 1.86%, 3.57%, and 4.82% when immersed in NaCl, Na2SO4, and MgSO4 solution. However, the losses are 1.67%, 2.79%, and 3.16% in rubberized concrete only at 24 weeks. Pozzolana‐based cement and after crumb rubber treatment, the rubberized concrete can resist chloride and sulfate solutions for a long duration.

“…Katherine E et al [ 25 ] used acoustic emission technology to study the wear resistance of ordinary concrete and rubber concrete, and found that the weight loss and wear depth of rubber concrete are significantly lower than that of ordinary concrete. Ruonan Zhu et al [ 26 ] studied the chlorine salt corrosion resistance of rubber concrete in 4% NaCl solution, which has certain guiding significance for the chlorine salt corrosion resistance of rubber concrete. Jian Liang et al [ 27 ] showed that under the action of chloride ion corrosion, rubber can delay the development of concrete cracks and reduce the peak value of steel corrosion.…”

In order to enhance the corrosion resistance of concrete to chloride salt, 5% NaCl solution was used to corrode ordinary concrete (OC) and rubber concrete (RC) with 5%, 10%, and 15% rubber content, respectively. By testing the compressive strength, mass, chloride ion concentration at different depths and relative dynamic elastic modulus, the erosion mechanism was analyzed by means of SEM scanning and EDS patterns, and the mechanical properties and deterioration degree of ordinary concrete (OC) and rubber concrete (RC) under the corrosion environment of chloride salt were studied. The results show that: the quality of rubber mixed into concrete increases first and then decreases, and rubber can increase the compressive strength of concrete, improve its internal structure. At the same time, the mechanical properties of concrete in the corrosion environment of chloride salt are improved to a certain extent, and the deterioration degree is reduced. Considering the comprehensive performance of OC and RC in the dry–wet alternation mechanism under chloride salt corrosion, the best content of rubber is 10%.

“…In the 60 °C environment, plastic deformation is mainly caused by pores and cracks in the cement matrix due to the sound elasticity of the rubber particles [12]. In a Cl-erosion environment, rubber concrete with rubber powder particle size of 3-6 mm and 5% admixture has a denser internal structure than normal concrete, due to the addition of rubber powder improving the microcrack structure of rubber concrete [13,14].…”

To develop the utilization of pasture fibers and waste tire rubber powder, the effect of different blending levels of modified pasture fibers (2 kg/m3, 3 kg/m3, and 4 kg/m3) on the loss rate of compressive toughness and softening characteristics of rubber powder concrete was studied. In addition, RapidAir457 system imaging analysis and microscopic electron microscope photo analysis were carried out to analyze the distribution pattern of modified pasture fibers and rubber powder in concrete. The results show that the peak load of concrete is higher than other pasture fiber dosing test groups when 3 kg/m3 is incorporated in 20 mesh and 60 mesh rubber powder. With the increase of pasture fiber content, the compressive toughness loss of MC60 group and MC80 group increased first and then decreased. The softening curve analysis showed that MC-3 was more capable of absorbing damage energy in the strain range of 0.0005–0.0009 than the MC-2 group. According to the RapidAir457 system imaging analysis, the pasture fibers form a web-like organization inside the concrete when the pasture fiber is mixed at 3 kg/m3.
