Fundamental Properties of Self-Compacting Concrete Utilizing Waste Rubber Tires-a Review

“…Some of the researchers used shredded rubber as short fibre, generally from 8.5 to 21.5 mm in length with an average of 12.5 mm [25], and in the form of 68 mm long strips. [26] 3. PROPERTIES OF SCC USING WASTE RUBBER…”

Mechanical Properties of Self-Consolidating Rubberized Concrete with Different Supplementary Cementing Materials

“…The reduction of the compressive strength with higher percentages of CR may be attributed to the poor strength of the ITZ between the rubber particles and surrounding mortar, as observed by many researchers. For example, Emiroglu et al [15] investigated the microstructure of the ITZ of rubberized concrete using Scanning Electron Microscopy (SEM) and found that the poor bonding between the rubber particles and mortar led to generate micro cracks started from and around the ITZ and affected negatively the mechanical properties. Also Najim and Hall [16] reported in their SEM investigation that a significant interfacial de-bonding and micro cracks were observed between the rubber particles and cement paste.…”

A study on dynamic modulus of self-consolidating rubberized concrete

“…Therefore, mechanical properties and elastic modulus of rubberized concrete gradually decrease with the addition of rubber particles into the mixture. One of the suggestions to improve the mortar phase is to enhance a strong bonding between rubber particles and cement paste (Eldin 1993, Topçu 1995, Khatib and Bayomy 1999, Güneyisi et al 2004, Emiroglu et al 2008, Aiello and Leuzzi 2010, Emiroglu et al 2012. It is well known that self-consolidating concrete has denser mortar phase than that of conventional concrete, and various filler materials used to improve rheology, strength and durability of concrete and, reduce cement content (Okamura and Ouchi 2003, Bartos 2005, EFNARC 2005.…”

A plain (without TRA) SCC and four different R-SCC mixtures having 15%, 30%, 45% and 60% TRA replacement by volume of coarse aggregate are produced.…”
