“…Compared with NC slabs, the CRC slabs with an 18% rubber substitution rate exhibited greater ductility and strain energyabsorbing ability. Hassanli et al [41] and Li et al [42] conducted cyclic bending tests on NRC elements. It was reported that NRC beams failed in ductile modes, and compared with the NC baseline, the flexural strength of the NRC beam with rubber contents of 6%, 12%, and 18% decreased by 2.3%, 1.7%, and 6%, respectively.…”

“…However, there are no established standards to determine the appropriate size, content, and surface treatment of rubber particles in concrete, and further explorations are needed to optimize the mixture techniques for rubber concrete. Despite this, previous research has demonstrated the potential benefits of using rubber concrete in structures that are exposed to dynamic, cyclic, impact, and collision loads, with components, such as beams and slabs [39][40][41][42][43][44], columns and walls [44][45][46][47][48][49][50], and beam-column joints [51][52][53][54][55], exhibiting excellent mechanical properties [56][57][58][59][60][61][62].…”

Substituting rubber particles for a portion of the standard coarse aggregates in concrete is regarded as a sustainable solution for tackling the issue of waste-tires disposal. In order to assess the structural performance of rubber concrete (RC), many studies have been conducted on the proportions, mechanical properties, curing conditions, usages, and serviceability performance of the material over the decades. This review systematically summarizes the mechanical properties (e.g., static and dynamic), testing method, and durability of RC, emphasizing its dynamic characteristics from the perspectives of material and component. The inclusion of rubber particles weakens the static properties of the concrete, while the low module of inherent rubbers improves the concrete dynamic properties, such as low stiffness degradation, high strain-rate sensitivity, excellent energy dissipations, and good ductility. With the increase in the strain rate, the improvement in energy absorption and ductility of the RC (0 to 30%) can increase to 110% and 80%, respectively. Concrete with a rubber volume fraction of less than 30% enhances both mechanical and long-term environmental performances. Moreover, RC shows good fire resistance, permeability, and freeze–thaw behavior; however, further research is needed to understand its constitutive model and the synergistic effects of additional materials.

“…New concrete mixes and concepts are being developed across the world [41,42,44,[51][52][53][54] for meeting sustainable infrastructure demands or to attain novel properties, and few studies are reported for India as well [55][56][57]. This could even include fibre-reinforced concrete (both natural [58,59] and artificial: basalt nano-fibre [60]; steel fibre [56]), recycled aggregate concrete [61], and carbon nanotube reinforced concrete [62], among others.…”

Fire and elevated temperature are important considerations for design of concrete structures, for both normal and nuclear facilities. In India, the present design guidelines for concrete subjected to fire and elevated temperature are limited to prescriptive minimum dimension and minimum cover. The other approach suggested is fire test based, and being resource intensive, is considered only for special cases of design. The various provisions of Indian standards are discussed and compared to the international standards. Fire test data for concrete/reinforcement properties at elevated temperature for Indian materials are scarce, and hence, the calculation methods are difficult to apply for Indian concrete. Validation of such methods for India is required, which again can only happen after generation of adequate database. The article highlights the present research needs for fire design of Indian concrete, along with development of analysis methodologies/guidelines for fire design of concrete structures, assessment of fire-affected concrete structures, and combination of the fire/temperature load with other extreme loads such as impact, seismic load, or missile load using advanced approaches. This article could serve as reference for designers as well as the starting point for several research initiatives in India and thereby is expected to improve the state of the art of fire design of concrete structures in India in the long term.
