“…Moreover, this reduction can be explained by the segregation caused by the rubber aggregates during the mixing of concrete which leads to the development of air content. Comparative results were noted by other authors [2,17,22]. According to E Guneyisi et al [16], the increasing rubber content reduced the fresh unit weight of the concrete.…”

“…As a consequence, according to the following studies [9,10,[14][15][16][17][18]] the replacement of natural aggregates with tire rubber aggregates considerably decreases the concrete and mortar strengths; while rubberized mixtures [11,[19][20][21][22]] demonstrated a greater deformability and ductility compared with common mixes.…”

This study presents experimental results about the effect of incorporating waste rubber aggregates in combination with waste glass powder or silica sand powder obtained from dune natural sand, on the performances of cementitious mixtures. Rubber aggregates (RW) were used to replace crushed sand in concrete mixes with ratios of 10%, 20%, 40% and 60%, while glass powder (GP) and natural sand powder (SP) were used to replace 15% of the cement weight. Nine different forms of concrete with the separate wastes and with the combination of them were designed and prepared. The mixtures were characterized in the fresh and hardened states by means of workability, fresh density, compressive and tensile strengths, propagation of ultrasonic waves and deformability tests. The water/binder ratio and superplasticizer percentage of all mixtures were maintained constant. The results showed that the strength increased with the incorporation of glass powder and rubber aggregates, especially with 10% and 20% RW contents. In addition, the developed rubberized concrete with the incorporation of glass powder presented higher fresh density and deformability, compared to the cementitious rubberized mixtures without GP. Furthermore, the simultaneous incorporation of rubber waste and glass powder enhanced the concretes workability due to the low GP and RW water absorptions. Recently, researchers worldwide up the challenge to assess the usability of this industrial waste in cementitious materials, however, their performance has to be defined. The most recent studies related to the use of rubber aggregates and chips obtained from the used tires milling as a partial replacement of fine and coarse aggregates should be highlighted [9-24]. Blessen et al. [9] studied the properties of high strength rubberized concrete that contains scrap tire rubber. Crumb rubber was used to replace natural fine aggregate from 0% to 20% in multiples of 2.5%. It was observed a significant improvement on the abrasion resistance and water absorption properties, while mechanical and durability of high strength rubberized concrete were observed to be less than that of the control mix. Similarly, Ganjian et al. [10] tested the effect of replacing coarse aggregates by chipped tire and cement by powder tire crumb. Based on the results, they obtained a reduction in compressive strength about 10-23% and 20-40% for replacing natural aggregates and cement with chipped rubber, powder rubber respectively. In addition, Aslani et al. [11] practiced the replacement of

“…A constant mixing water-cement (w/c) ratio of 0.6 was used. This is similar to the mix and w/c ratio used in related studies [1][2]13]. Mortar specimens were cured in water for 28 days at a temperature of about 21 o C. After 28 days curing, tests were performed on the specimens in three categories: physical, mechanical and microscale analysis.…”

Using industrial wastes and local materials as artificial aggregates in cement based materials remains a relevant measure for conservation of natural sources. In this study, novel cementitious mixes containing pulverized ceramic blended cement, ceramic aggregate and laterite were systematically combined to produce cement mortars. The mortar specimens were cured in water for a maximum of 28 days. At maturity, nondestructive tests, X-ray CT scan and Ultrasonic pulse velocity, were performed on hardened mortars. Thereafter, a series of predefined properties, namely dry bulk density, compressive and flexural strength, water absorption coefficient (due to capillary) of the hardened mortars were determined. Finally, in order to understand the hydration mechanism of the materials as it relates to the strength properties, microscale tests, SEM and XRD, were used to examine the fragments of the selected mortars. From the results, a mortar sample containing 10% ceramic powder and 100% ceramic aggregate as replacements for cement and sand respectively, gave higher strength values than the reference and other mixes.Microstructural analysis of the best mix revealed that it has larger proportions of ettringite, portlandite and calcite than the reference mix, and this could be responsible for the strength 2 gained. Thus, despite the apparent low reactivity of crushed ceramic material, this can improve bonding in cement-based mixture, when used at an appropriate concentration.
