Surface Characterization of Recycled Tire Rubber to Be Used in Cement Paste Matrix

Positive Interaction of Industrial and Recycled Steel Fibres in Fibre Reinforced Concrete

“…According to literature data (Segre, Joekes 2000;Marques et al 2004;Segre et al 2002), different rubber pre-treatments are available, but the one most often applied is immersion in the saturated sodium hydroxide solution. Meanwhile, due to a high amount of alkaline in concrete during the exposure period, the presence of sodium hydroxide could be the determinant factor for the composite's durability (Marques et al 2008).…”

Effects of partial oxidation of crumb rubber on properties of rubberized mortar

“…FTIR was used to explore functional groups on surfaces of the treated crumb rubber as proposed by Segre et al [16]. SEM was used to observe microstructures of mortars.…”

Optimisation of rubberised concrete with high rubber content: An experimental investigation

“…To improve rubber-cement paste chemical/physical bonding [18], several rubber pre-treatments have been investigated such as washing with water [21,35,42], polyvinyl alcohol [43], NaOH [13,41,44,45], Ca(OH) 2 [46], silane coupling agents [47], organic sulphur compounds [48] or acid [40], as well as partial oxidation of the rubber surface [49], exposure to UV radiations [50] or pre-coating with cement [51], mortar [26], silica fume [39], limestone [52] or sand [45]. Despite some success in rubber pre-treatments (strength increase in the range of 3-40% [18,26,41,51,52]), results are often scattered and inconclusive, particularly when mixes with pre-treated rubber are not compared to mixes with as-received rubber [35,42].…”
