| dc.description.abstract | This experimental research is focused on the development of self-compacting mortar
incorporating recycled glass aggregate (SCM-RGA) as partial substitution of fine aggregate (wt 0%,
10%, 20%, 30%, 40% and 50%). The fresh and hardened mechanical properties as well as durability of
SCM-RGA mixes were investigated. Limestone powder (LP) was used as filler that constitutes 20% of
the powder volume to reduce the amount of cement. The SCM-RGA mixtures were designed based on
Japanese mix design method. The experimental test results showed that the slump flow of SCM-RGA
mixes decreased and V-funnel flow time increased when the content of recycled glass aggregate
(RGA) increased. The bulk density, compressive strength, flexural strength, water absorption and
sorptivity of SCM-RGA mixes were decreased as RGA content increased. Moreover, the accelerated
mortar bar test results showed that the expansion due to alkali–silica reaction (ASR) of SCM-RGA
mixes increased as the content of RGA increased although the expansion of all mixes were within
acceptable limit and potentially innocuous. In conclusion, up to 30% of RGA can be successfully
integrated in SCM mixes that offers comparable strength performance, sorptivity enhancement and
without long term detrimental ASR effect, and thus, contributes towards sustainable solid waste
management, conservation of natural resources and environmental protection. | en_US |
