“…Six core specimens from the aged CRC bridge deck were further investigated with respect to: (1) the spilt strength test; (2) the CRC density measure by the wax-immersion method; (3) the rubber content measure and calculation; (4) crack observation; and (5) the layered distribution of rubber crumbs with the computerized image scanning method. The details of the investigation can be found in [ 13 ] by the current authors. It was found that the CRC specimens were in good condition and retained excellent material integrity, with the flexural strength converted from the split strength data exceeding its original magnitude.…”

Crumb rubber concrete (CRC) is a concrete that contains rubber crumbs. This article presents a study of three experiments on long aged CRC specimens that were cored from a decade old CRC bridge deck in Tianjin, China. The three experimental tests conducted were: (1) the flexural stress–strain test on semi-circular disk specimens; (2) the accelerated steel-rebar corrosion test and (3) the carbonation test. In addition, the in situ carbonation test was also carried out on the CRC bridge deck. The flexural stress–strain test results showed that the CRC semi-circular disk specimens exhibited a ductile pattern and high-energy absorbing capacity with its flexural tensile strength being at 5 MPa and the flexural modulus of 10 GPa. The steel corrosion rust rate via the calculation of steel mass loss before and after the test in the accelerated steel-rebar corrosion test remained extremely low. The carbonation test results showed that in comparison with the prediction of two popular carbonation models, the carbonation in the CRC bridge deck took place at a much slower rate during the last 13 years. All of the results obtained in this study are reported for the first-time and indicate that these CRC cored specimens exhibit good mechanical properties and excellent durability characteristics after a decade in service, which may provide the technical knowledge for the possible future application of CRC in concrete constructions.

“…When using tire rubber powder with a 5% replacement ratio as a sand filler, the amount of eggshell powder replacing cement was increased from 0% to 15%, and the carbonation depth decreased by 40%, indicating that eggshell powder has a better filling effect than cement to stop the deep penetration of CO 2 [81]. However, other scholars have presented opposite views [74,80,82]. Similarly, the carbonation resistance of self-compacting rubber concrete is better than that of ordinary concrete.…”

Environmental problems caused by waste tires are becoming increasingly prominent. There is an urgent need to find a green way to dispose of waste tires, and scholars have made considerable efforts in this regard. In the construction industry, rubber extracted from waste tires can be added to concrete to alleviate environmental problems to a certain extent. As a new building material, rubber concrete has superior properties compared to ordinary concrete and has been widely used in many fields. Numerous studies have been conducted worldwide to investigate the effect of waste tire rubber on the performance of concrete. It has been reported that the addition of waste tire rubber has a significant influence on the performance of concrete. Workability influences the hardened performance of rubber concrete, especially the durability. Based on the current research results, the workability and durability of concrete manufactured with waste tire rubber, including water absorption and permeability, carbonation resistance, chloride ion permeability resistance, and freeze-thaw resistance, are summarized in this paper. It is concluded that the addition of waste tires has a negative effect on the workability of concrete. In terms of durability, concrete exhibits better chloride ion penetration resistance and frost resistance, with a higher water absorption rate, and lower anti-permeability and carbonation resistance owing to the addition of waste tire rubber.

“…Hence, one of the ideologies of recycling scientists and experts is to utilize the waste material as additive in cement-based materials. Crumb rubber (CR) as an additive in concrete is very common nowadays in the field of building materials, as it decreases the stiffness of the concrete [13], improves energy absorption and deformation capacity, and decreases chloride permeability [14,15]. The overall results of these findings show a considerable decline in the stiffness and strength of the concrete after adding CR, mainly due to physical properties and the interaction with aggregates [16][17][18][19][20].…”

The existing form of self-compacting concrete (SCC) comprises of a large amount of powdered and fine materials. In this study, a part of the cementitious material was replaced with constant high-volume fly ash, and a portion of fine aggregates was substituted by crumb rubber (CR). Besides that, silica fume (SF) was added, with the hope that by implementing a new type of nanomaterial, the loss in mechanical strength due to previous modifications such as rubberization and replacement will be prevented. Two variables were found to influence the constituent/component in the mix design: SF and CR. The proportion of SF varies from 0% to 10%, while that of CR from 0% to 30% by volume of the total river sand, where 55% of cement was replaced by the fly ash. A total of 13 rubberized SCC samples with CR and SF as controlling variables were made, and their design mix was produced by a Design of Experiment (DOE) under the Response Surface Methodology (RSM). The results reveal a slight increase in the mechanical properties with the addition of SF. The theoretical mathematical models and equation for each different mechanical strength were also developed after incorporating the experimental results into the software.
