This study aims to develop a roof tile with facemask/synthetic fiber to determine whether
it improves concrete roof tile's physical and mechanical properties. This study involves
collecting used masks, sanitizing, shredding, and mixing them to make concrete roof tiles
Cement, sand, water, oxide colors, and facemasks was utilized and enhanced the
substances had to manufacture the roof tile. The face mask was cleaned first by washing
it because of its toxic waste and safety purposes. The researchers shredded the facemask
with the size of 2mm to 3mm. The mixture was poured into a molder with a size of 420
mm in length, 330 mm in width, 56 mm in depth, and a thickness of 30 mm. The last
process is to remove the roof tile in the molder. The ratio of roof tile mixture is 1:2 for
cement and aggregates with added 0%, 3%, and 7% of shredded facemasks. The
researchers conducted tests such as a water absorption test, transverse strength test (3 pt.
static bending), and face screw test based on ASTM. The test result showed that the
waste facemask/synthetic fiber improved concrete roof tiles' physical and mechanical
properties. The prototype was evaluated by 15 evaluators of licensed civil engineers, civil
engineering students, and TUP professors. The prototype received a "Very Acceptable"
descriptive grade and an overall rating of 4.13.
