“…This is also because the WRTC used in this study was an inactive filler. An inactive filler will cause an increase in the hardness of the rubber, but it will decrease the tensile strength of the rubber [8]. This finding is consistent with previous research that found tensile strength to be inversely proportional to rubber hardness [9].…”

“…Moreover, the addition of the WRTC caused a decrease in the mechanical properties of the rubber, but it increased the damping ratio of the rubber [6][7]. Meanwhile, based on [8], the addition of the WRTC increased the hardness of the rubber but decreased the tensile strength of the rubber. This was consistent with the findings of a study [9], which found that the hardness of rubber was inversely proportional to its tensile strength.…”

To reduce lateral deformation due to earthquake shake has been carried out by strengthening techniques. Such techniques require additional structural elements such as bracing or shear wall, if not applying additional new materials on beams or columns such as CFRP. This study focuses on the formation of the hybrid rubber dampers from materials such as natural rubber compound (NRC), waste of rubber tire crumb (WRTC), compacted natural sand, iron sand, and silica sand. The main goal of this research is to investigate the dynamic properties of hybrid materials of compacted various sands encapsuled with the NRC and WRTC compound. Nonetheless, the mechanical properties of rubber, such as tensile strength and modulus of elasticity, were also tested. In this research, the specimens were in the form of a square block of 100 x 100 mm2 base and 25 mm thickness and consisted of two types of specimens for reference i.e., fully natural rubber compound (NRC) and blended NRC with 25% by volume of the WRTC, namely MRTC. Furthermore, other three types of hybrid viscoelastic dampers (HVD) were also provided i.e., 1) compacted natural sand, 2) compacted iron sand, and 3) compacted silica sand, which were all wrapped with WRTC in a proportion of 3:4 by volume. The results show that the addition of the MRTC reduces the tensile strength and elastic modulus in comparison to the NRC but increases the damping properties. Moreover, the elaboration of compacted natural sand, iron sand, and silica sand in the HVD also shows an increase in the damping properties up to 200%.
