Masonry wall has been used for ages as a part of non-engineered building structures, due
to its ease of manufacture, strength, and stiffness to support gravity loads, but brittle enough to resist
earthquake shake. One solution to increase its ductility when the earthquake shake stroked, ductile
materials at bed joints that binding the masonries may apply. Mortar is a composite material
consisting of sands, cement, and water that is generally used for masonry construction as a binder at
bed joints. On the other hand, rubber has been used to isolate vibration of machinery because of its
good damping behaviours. Those materials will be mixed and be elaborated to provide a ductile
mortar binder at bed joints. This research aims to investigate the mechanical properties and the
damping behaviour of hardened mortar with rubber tire crumbs at proportions of 0%, 40%, and
60%. Three types of specimens in forms of mortar cubes of 50x50x50 mm3
, tensile specimens and
mortar beams of 100x100x500 mm3 were tested to provide strength and damping behaviour. The
addition of rubber tire crumbs in the mortar decreased the compressive strength, tensile strength,
flexural strength and unit weight. Despite its weakness in the mechanical strengths, the addition of
rubber tire crumbs could increase the damping behaviour significantly. This research recommended
that mortar containing RTC is still appropriate use for non-structural component although it has low
mechanical properties |
