“…This is not in line with previous studies reporting much lower compressive strength when replacing coarse aggregates as opposed to fine aggregates [24]. This deviation can be attributed to comparisons often being made between different amounts of rubber.…”

“…Other factors that reduce RuC strength include segregation, lower overall stiffness of the composite and casting and consolidation techniques [28]. Whilst such reduction is well documented in the literature [14,17,24,25,[29][30][31], strength seems to be influenced by rubber content, size and properties, as well as mix parameters and proportions (i.e. water to binder ratio (w/b), type of chemical admixture and binder material).…”

“…The increase in porosity and entrapped air content (up to 30% at 25% rubber replacement by volume [20]) is conceivably the main reason behind the poor fresh performance of RuC [22]. Such increase may be attributed to rubber hydrophobicity, irregular shape, rough texture, contamination, interlock among rubber particles and excessive friction with cement paste [23,24]. Other factors include flocculation among fine rubber particles, particle gradation and moisture content [22].…”

“…In mortars with 5% rubber, a decrease of approximately 35% in compressive strength is observed in comparison with MS0, while the approximate reductions in compressive strength of the mortars with 10% and 15% rubber content are 61% and 68% respectively. That an increase in volume percentage of rubber particles in the mortar from 10 to 15% reduces the compressive strength at a slower rate has also been observed and reported by other authors [Eldin and Senouci 1994]. Reduction in compressive strength and modulus was anticipated because rubber particles have lower modulus and higher resiliency in comparison with sand grains.…”

Sulfur polymer mortars are composite materials in which modified sulfur is the binder while sand and other fillers are used as aggregates. Sulfur-based composite materials are characterized by their high chemical and mechanical properties along with fast setting behavior. However, sulfur modification is essential in order to achieve sulfur mortars with enhanced characteristics. In this study, incorporation of crumb tire rubber in dicyclopentadiene-modified sulfur-based mortars, as some replacement of sand, is evaluated. Use of crumb tire rubber influences the compressive stress-strain behavior of the mortars significantly. While the compressive strength of the rubber-added mortars is reduced dramatically, the postpeak response of the mortars is of the great interest. Use of a reactive-mixing method improves the compressive strength of rubber-added sulfur polymer mortars up to approximately 25%. Scanning electron microscopy observations confirm better adhesion between the rubber particles and sulfur polymer matrix via reactive mixing. Furthermore, it is clarified that the crumb tire rubber type and presence of a curing agent during the mortar preparation process affect the mechanical properties of the sulfur mortar.

As a way of solving the environmental problem of waste tires, we introduce rubber concrete made from a rubber solution. The rubber solution was prepared by dissolving vulcanized waste tire scrap in a solvent mixture of tetrachloroethane and methylene chloride. The elastic rubber concrete was then manufactured by mold processing, with compositions comprising of rubber solution and aggregates. Carbon dioxide super‐critical fluid was used to extract solvent from mixture of rubber solution and aggregates. The compressive strength and strain of the rubber concrete were 93.4 MPa and 6.7%, respectively. These results indicated that the rubber concrete made in this study corresponded to ultrahigh strength and high elastic properties compared with conventional cement concrete. Weathering properties on the elastic rubber concrete were examined. The time of freeze‐thaw, lasting up to 10 days, did not affect the properties of the elastic rubber concrete. According to chemical tests with sodium chloride and sulfuric acid, it was found that the elastic rubber concrete was not affected by these chemicals for up to 240 days. Changing the outdoor condition for up to 720 days did not change the mechanical properties. POLYM. ENG. SCI., 2009. © 2009 Society of Plastics Engineers
