| 总结: | The accumulation non-biodegradable waste glass in the overpopulated landfills of
developed and developing countries is becoming a serious environmental issue. Numerous
researches have been conducted in the past to study the application of waste glass as an
alternative material in concrete production. The chemical properties such as high silica content
making it an attractive material to be used as partial cement replacement. This research
investigates the potential of powdered green waste glass (PGWG) as partial cement replacement
in mortar with the research aim of assessing its pozzolanicity in relation to the fineness of the
PGWG (>75μm, <75μm ->38μm, and <38μm) and percentage of cement replacement by weight
(10%, 20%, 30%, and 40%). Mortar cubes were prepared with water to cement ratio of 0.45, and
cement to sand ratio of 0.6. The mortar cubes are cured in room temperature of± 32ᴼC with 90%
relative humidity and prepared for compressive strength test. Modified cement paste with the
same PGWG size and cement replacement percentage were prepared for FTIR analysis. Mortars
and cement paste with 10% cement replacement and PGWG size of <38μm recorded the highest
compressive strength test result and display the highest degree of pozzolanic activity from the
FTIR analysis respectively. |
