“…From the early research works [6], it was clear that substituting natural aggregates by rubber particles has led to a significant drop in the compressive strength. Subsequent investigations [7][8][9] confirmed earlier findings and highlighted the improved damping properties of rubberized concrete [10][11][12]. e optimization of the rubberized concrete mix, although a complex task, may lead to high-value applications from the point of view of sustainability [13].…”

The paper presents experimental and numerical investigations on the behaviour of rubberized concrete short columns confined with aramid fibre reinforced polymer (AFRP) subjected to compression. Additionally, the possibilities to substitute fine aggregate with crumb rubber granules, obtained from discarded worn tires, in structural concrete is also assessed. Because replacing traditional concrete aggregates by rubber particles leads to a significant loss in compressive strength, the authors highlight the use of AFRP confinement to partially or fully restore the compressive strength by applying a number of 1, 2, and 3 layers. Analytical models available for confined regular concrete are used to predict the peak stresses and the corresponding peak strains. Some analytical models give accurate results in terms of peak stress while others better approximate the ultimate strain. The full stress-strain curve of rubberized concrete and the experimentally obtained values for the material properties of AFRP are used as input data for the numerical modelling. A good agreement is found between the results obtained for the peak stress and corresponding axial strain from both the numerical simulations and the experimental investigations.

“…Several previous studies indicated that the use of rubber tire crumbs reduced mechanical characteristics of concrete/mortar. [20][21][22][23][24][25][26] It should be noted, however, that the compressive strength of brick masonry walls is not only influenced by the strength of the mortar but also limited by the strength of the brick. Sometimes the addition of mortar strength no longer gives significant changes to the compressive strength of brick masonry walls.…”

“…Several studies indicated that the use of rubber tire crumbs reduced the compressive, tensile and flexural strengths. [20][21][22][23][24][25][26] Increasing the amount of the rubber crumb will result in further decrease in strength properties. The strength reduction is attributed to the weak bonding between the rubber particles and the cement matrix.…”

Rubber tire waste is relatively difficult to be recycled into new tires. The volume of the tire wastes increases with the societal needs and time. Many efforts have utilised rubber tire wastes as an additional material in pavements, geotechnical work and concrete. However, a relatively small number of research works have been applying the wastes to improve the performance of masonry brick wall. This paper presents a review of previous studies on the application of rubber tire crumbs in structural elements and its possibilities to improve the performance of masonry brick walls. Many research works concluded that the rubber tire crumbs are potential materials in the mortar bed joint to increase the ductility of masonry brick wall. The use of rubber tire crumbs as mortar bed joint in masonry brick wall shows a large elastic deformation before failure. This paper recommends 60% of rubber tire crumbs in the mortar bed joint as an optimum amount to increase the ductility of masonry brick wall. At optimum amount, the mortar can be classified as lightweight concrete/mortar and meets the minimum requirement for the compressive strength of masonry wall. The review also recommends a laboratory experiment to study the contribution of mortar bed joint using rubber tire crumbs in loaddeflection behaviour and ductility of the masonry brick wall. A finite element model needs to be developed to have a general model of the masonry brick wall.

“…This is attributed to the thermal conductivity of the materials, which are lower than that of cement. Fiore et al [60] found that the inclusion of 10% by volume, of fine rubber aggregate results in a 23% improvement of thermal insulation. These studies have shown that rubberised concrete containing either chipped or crumb rubber particles exhibit has a lower thermal conductivity when compared to plain concrete.…”

A review of Waste Tyre Rubber as an Alternative Concrete Consituent Material

The current global waste tyre generation far exceeds its consumption in terms of recycling and re-use. The traditional recycling and re-use methods like thermal incineration have proven ineffective, costly and in some cases environmentally unsustainable. Particularly, in developing countries where some of the sophisticated techniques required to process tyres to allow them to be utilised are either too costly or have not yet been developed. The situation has resulted in accumulation of large waste tyre stockpiles that pose health and safety risks. To combat the problem, the use of waste tyre rubber in concrete construction has been proposed. Several studies have been conducted to assess the effects of the inclusion of waste tyre rubber in its different forms (fibres, particles), for concrete production and the results are promising. Although there are some apparent demerits to the inclusion of tyre rubber in concrete, the potential benefits seem to overshadow the negatives. This paper reviews published research on the scientific and technical viability of using waste tyre rubber in concrete production. It discusses the production and properties of waste tyre particles. It highlights advances made with regards to the incorporation of tyre rubber material in concrete, focusing on the engineering properties of the tyre rubber modified concrete. In conclusion, recommendations for future research and possible application for the material will be discussed.
