Mechanical properties and constitutive equations of concrete containing a low volume of tire rubber particles

Analysis and Prediction of Compressive Properties for Steel Fiber‐and‐Nanosilica‐Reinforced Crumb Rubber Concrete

“…However, the growth of peak strain is much higher than that in other literature studies [16]. For rubber and steel fiber addition, the effect of rubber [12] and steel fibers on the deformation of concrete exceeds the effect of rubber and steel fibers on the strength of concrete, which causes a large deformation of SFNS-CRC. is is attributed to the fact that steel fibers can inhibit the development of cracks in concrete and hinder the development of macrocracks.…”

“…In order to use CRC for the structural members and layers with high stress, it is necessary to increase the compressive and splitting tensile strength of CRC and to set up its constitutive equation. Li et al [12] conducted the uniaxial compressive tests on the CRC with low rubber volume content; the uniaxial compressive constitutive models of low-volume rubber concrete were established and further improved through the incorporation of rubber particles equivalent to the sand ratio factor to predict the stress-strain relationship of rubber concrete and promote the application of rubber concrete in structural design.…”

Physical and mechanical behaviour of a fibre-reinforced rubber membrane with self-healing purposes via microwave heating

“…For example, rubber from waste tyres has been used for a variety of civil engineering applications such as scrap tyres in road construction [3], reinforced-concrete with scrap tyre rubber [4], use of waste tyre rubber in asphalt and Portland cement concrete [5], amongst others. Additionally, recycled rubber powder in different sizes has been used in the development of new asphalt mixtures and cement-based materials, flooring for playgrounds and sports stadiums, as shock absorbing mats, paving blocks, and roofing materials [6]. However, authors have not found in literature applications of the use of rubber powder in the manufacture of new polymeric membranes with energy purposes, such as: smart membranes for walls acoustic insulation or roofs waterproofing, and reinforced-membranes with self-healing properties.…”

“…By this way, waste tyres and its http://dx.doi.org/10.1016/j.conbuildmat.2015.06.068 0950-0618/Ó 2015 Elsevier Ltd. All rights reserved. derivatives such as rubber powder and rigid steel metal fibres, have become natural candidates for the development of new civil engineering materials with improved properties [1][2][3][4][5][6]. For example, rubber from waste tyres has been used for a variety of civil engineering applications such as scrap tyres in road construction [3], reinforced-concrete with scrap tyre rubber [4], use of waste tyre rubber in asphalt and Portland cement concrete [5], amongst others.…”

Fatigue performance of rubber-modified recycled aggregate concrete (RRAC) for pavement

“…Recycling is one of the best ways to deal with waste tires up to now. Adding crushed waste tires to concrete to produce rubberized concrete (RC) has gained widespread attention among researchers worldwide, and research areas have included constitutive relationships [10], fatigue performance [11], impact performance [12], freeze/thaw performance [13] and durability performance [14] of RC, among others. Research works shown that generally, concrete with small volume of rubber were used as structural components [15,16].…”
