| dc.description.abstract | If a multi-storied building catches fire, the walls collapse first, followed by columns,
beams, and slabs. The building collapsed, and many people died until the fire was
extinguished by evacuating the people and belongings inside. The study aims to
increase concrete strength and make it last longer in fire than normal concrete.
Aluminum increases the strength of concrete by resisting fire and bonding better with
concrete. Therefore, in this experiment, waste drink cans and pharmaceutical blisters
have been used as aluminum. In this study, partially replaced (5%, 10%, 15%, & 20%)
recycled pharmaceutical blister as fine aggregate and partially replaced (5%, 10%, 15%,
& 20%) recycled drink cans as coarse aggregate. The pharmaceutical blister & drinks
can sizes used were 2mm × 2mm and 17.5mm × 17.5mm, the water-cement ratio was
0.55, and for 54 cylinders, the concrete mixing ratio was 1:1.74:2.72, the concrete
mixing ratio followed by mix design. According to the results, there was a decreased
compressive strength of pharmaceutical blister mix concrete. After 28 days, the
maximum compressive strength at 5% drink cans mixed concrete at normal temperature
and 60 minutes at 1000℃ was 25.7MPa and 19.27MPa, respectively, whereas the
maximum compressive strength for normal concrete, at normal temperature and 60
minutes at 1000℃, was 20.02MPa and 13.07Mpa, respectively, and for pharmaceutical
blister mix concrete at 5%, 22.05MPa and 17.88MPa, respectively | en_US |
