Effect of Curing Methods on Carbonation Depth of Rubberised Fibre Mortar

Abstract:

In Malaysia, more than 50,000 tons of used automobile tyres are stockpiled annually. This subsequently causes a major threat to the environment. This article focus on the durability of mortar with treated crumb rubber (TCR) as partial replacement for fine aggregate (FA) and addition of oil palm fruit fibre (OPFF) in the mix. For every 0.5% OPFF additions, there were 10% TCR replacements up to 30%, resulting in 16 different mixes with constant water cement ratio. The specimens were cured either by water ponding or water sprinkling for 28 days, after which they were preconditioned and subsequent carbonation depth measurement was made. The results showed that the carbonation depth lies between 2.5mm to 6.7mm. These confirmed that rubberised fibre mortar achieved carbonation depth of less than 15mm, the tolerable limit.
