“…Several authors have indicated that the decomposition of rubber aggregates starts rapidly at a temperature of 300°C [34][35][36]. The same result was demonstrated by thermo gravimetric analysis in the study of Gupta et al [3]. They showed a rapid decrease in the weight above 300°C and 70% of weight loss was observed when temperature reached 800°C.…”

“…This was also indicated in the research of Onuaguluchi [23]. The increase of the water absorption percentage was due to improper compaction of rubberized concretes owing to the lower density of rubber [3].…”

“…The addition of a rubber aggregates appropriate amount in concretes showed to be efficacious in reducing micro-cracks due to elevated temperature [2]. Gupta et al [3] observed that the exposure of rubberized concretes, with content up to 10% of rubber fiber replacing natural sand, to elevated temperature up to 150°C has little effect on their residual properties. It was also observed that at temperatures beyond 150°C and rubber fiber replacement higher than 5%, the decomposition of rubber fiber leads to rapid decline in the rubberized concrete residual properties.…”

Scrap tyres are one of the most important wastes. They can be used in different ways because of their availability and their non-degradable nature. This paper aims to demonstrate their reuse through durability properties experimental assessment of lightweight concretes aged five years, incorporating rubber aggregates as partial replacement of 5%, 7.5% and 10% of coarse/fine and coarse aggregates. The effect of the rubber aggregates on the lightweight concretes durability has been analysed. Firstly, the water absorption was evaluated, and then the mass losses were measured through many tests: freeze-thaw, elevated temperature and attack by Na2SO4 and HCl solutions. Wetting-drying cycles were carried out in order to accelerate the aging of the studied lightweight concretes and to reduce the tests duration. It has been observed that the water absorption decreased with small rubber content. The mass losses of the mixes were almost depending on rubber aggregates content and size, and the exposures duration.

“…Numerous studies concern the use of waste rubber in cement concrete [7,[10][11][12][15][16][17][18][19]. The addition of waste rubber usually significantly reduced the strength parameters of these composites [11,17,[20][21][22]. However, with a substitution not exceeding 20%, a significant reduction in strength can be avoided.…”

“…Rubberized concrete shows high resistance to cyclic freeze-thawing, acid attack and chloride ion penetration [16]. The authors of publications [17,18] also examined the behavior of mortars containing waste rubber at elevated temperatures, in the order of 150-400 • C. This approach is important due to the possibility of the release of harmful substances during a fire. It was found that at 3-10% waste rubber content there is no risk of the modifier burning.…”

The dynamic development of the automotive industry and improvements in quality of life have caused a significant increase in the production of car tires. Unfortunately, when the useful life of these products comes to an end, the problem of their disposal arises. The article presents the results of tests of epoxy mortars in which granules made from waste tires were used as a substitute for sand in the amount of 0, 20, 40, 60, 80 and 100% vol. respectively. The available literature lacks information about resin composites that arise with such a large or complete replacement of sand with rubber waste. Along with the increase in the content of waste, the values of strength parameters of composites decreased; however, a material characterized by very low water absorption, that is lightweight and with a low thermal conduction coefficient was obtained. Using the ADINA program, numerical simulations were carried out regarding the temperature distribution in a part of the building structure containing modified rubber mortar. The results of the simulation confirmed the possibility of practical use of the obtained composite due to its good thermal insulation properties. This approach to testing composites modified with rubber waste is innovative.

The durability of concrete material after exposure to elevated temperatures is important 17 for the serviceability prediction of concrete structures in a fire disaster scenario. Existing 18 researches show that an appropriate amount of basalt fiber can significantly improve the 19 splitting tensile strength and chloride penetration resistance of concrete. However, the 20 mechanical properties of basalt fiber concrete after elevated temperatures and its 21 durability properties are still not clear. In this paper, the mechanical properties, 22 carbonization law and chloride ion penetration law of ordinary concrete and basalt fiber 23 concrete under high temperatures are studied. The concept of a burnt layer for concrete 24 exposed to elevated temperatures is proposed, and the thickness of this burnt layer for 25 concrete under different temperatures were measured. The results show that the addition 26 of basalt fiber can inhibit the carbonization of concrete at elevated temperatures, 27 diminish the thickness of the burnt layer, and significantly improve the chloride 28 penetration resistance of concrete.
