| Summary, etc. |
Perlite, a lightweight volcanic rock with excellent thermal insulation, soundproofing, and<br/><br/>fire resistance, is a promising additive for improving the strength and flexibility of cement-<br/>bonded boards, which are typically heavy and prone to cracking. Researchers developed 12<br/><br/>mix designs with cement-to-raw material ratios of 30:70, 40:60, 50:50, and 60:40. These<br/>mixes included varying proportions of perlite, coconut coir fiber, and silica sand (5:9:86,<br/>10:9:81, and 15:9:76) combined with Portland cement and a water-cement ratio of 0.6,<br/>targeting a density of 0.8 g/cc. The boards underwent Apparent Density, Modulus of<br/>Rupture, and Nail-head pull-through testing based on the Philippine National Standard ISO<br/><br/>8336:2022 for fiber-cement flat sheets. Among 12 mix designs tested, the 50:50 cement-to-<br/>raw material ratio with a 10:9:81 blend achieved the best compactness (- 1.29 variation).<br/><br/>Mixes M1 (40:60) and M2 (50:50) with a 5:9:86 ratio exceeded MOR standards (4.39 MPa<br/>and 4.82 MPa). Mix M4 (30:70, 10:9:81 ratio) performed poorly, with 0.66MPa MOR and<br/>low NHPT resistance (290.93N). The 5:9:86 ratio demonstrated superior moisture<br/>management and structural integrity. Prototype evaluation scored 4.00 overall, deemed<br/>"Very Acceptable" for aesthetics, durability, safety, and marketability. Perlite was strongly<br/>supported as a key additive for Coco Coir fiber cement boards. |
