TL;DR: In this paper, the performance of concrete mixtures incorporating 5%, 7.5% and 10% of discarded tyre rubber as aggregate and cement replacements was evaluated. But the results were limited to two sets of concrete specimens.

TL;DR: In this article, the effect of rubber particle size, percentage replacement and various treatment methods on different mechanical properties of rubber concrete, studied over the last 30 years, was considered and a rubber treatment method that can address the concerns of high flammability and the resultant release of noxious gases from the rubber particles, when exposed to fire.

TL;DR: In this paper, the performance of concrete that contains rubber aggregate made from used tyres (CTA) has been studied since the early 1990s, and the results showed that 5%, 10% and 15% of the volume of natural aggregate (NA) were replaced by aggregate derived from used tires (TA).

TL;DR: In this paper, three groups of singly-sized rubber particle samples (3mm, 0.5mm and 0.3mm) and one sample of continuous size grading (prepared by blending the three singlysized samples to form the same particle distribution curve of sand) were used to replace 20% of the natural fine aggregate by volume.

TL;DR: In this article, the paving blocks based on two cement types were used to replace aggregate with waste marble, and physical and mechanical tests were performed on blocks so produced, and the cement type turns out to be an important factor.

TL;DR: The workability and mechanical properties of mortar containing shredded automobile and truck tyres were evaluated in this paper, where two different shapes of rubber particles were used as constituents of mortar: (1) granules about 2 mm in diameter, and (2) shreds having two sizes which were, nominally, 5.5 mm×1.2 mm and 10.8 mm × 1.8mm (length×diameter).
Abstract: The workability and mechanical properties of mortar containing shredded automobile and truck tyres were evaluated. Two different shapes of rubber particles were used as constituents of mortar: (1) granules about 2 mm in diameter, and (2) shreds having two sizes which were, nominally, 5.5 mm×1.2 mm and 10.8 mm×1.8 mm (length×diameter). As expected, the geometry of the rubber particles influenced the fracture behaviour of rubber-containing mortar. The addition of rubber led to a decrease in flexural strength and plastic shrinkage cracking of mortar. The crack width and crack length due to plastic shrinkage were reduced for mortar containing the 10.8×1.8 mm rubber shreds compared with a mortar without shreds. The rheological properties of the mortar containing rubber shreds were comparable to those of a mortar without rubber and yielded lower plastic viscosity than a mortar containing 25.4 mm×15 μm (length×diameter) polypropylene fibres. The alkaline stability of rubber in mortar was also evaluated by immersing rubber shreds in NaOH and Ca(OH)2 solutions for 4 mon and the results showed that there is less than 20% change in stress and strain value. The findings of the research suggest that automobile and truck tyres can be recycled by shredding and incorporating them into mortar and probably concrete for certain infrastructural applications. © 1998 Chapman & Hall
