Wood Scraps as Alternative Raw Materials for the Manufacture of Linear Wood Ceiling Plank

Abstract

The study investigates the development and performance wood ceiling plank adhere with 60% gorilla glue as a sustainable and economical alternative as ceiling plank materials. It evaluates the mechanical and physical properties of wood ceiling plank, including density, water content, flexural strength, tensile strength and compressive strength based on varying proportions of wood scraps with curing durations of 10 days, following ASTM C140 and ASTM C78/C78M standard.  Two mix designs were examined: Mix Design 1 with 10% wood dust, 30% wood shavings, and 60% gorilla glue; Mix Design 2 with 30% wood dust, 10% wood shavings, and 60% gorilla glue. The results show that density increases with low wood dust and wood shavings content, and water content is greater with 30% wood dust with 10% wood chips. Flexural strength is significantly affected by wood scraps, the highest flexural strength, 38.272 MPa, with a mean of 28.57 MPa, was attained after 10 days by Sample 1, which contained 10% wood dust, 30% wood shavings, and 60% gorilla glue. The highest compressive strength, 168.667 MPa, with a mean of 85.4 MPa, was attained after 10 days by Sample 1, which contained 10% wood dust, 30% wood shavings, and 60% gorilla glue. The highest compressive strength, 0.529 MPa, with a mean of 0.52 MPa, was attained after 10 days by Sample 1, which contained 10% wood dust, 30% wood shavings, and 60% gorilla glue. In accordance with the cost analysis, wood ceiling planks are more cost-effective than PVC ceiling planks, with a production cost of ₱4,925.25 as opposed to ₱40,800 for PVC. Thus, a total of ₱35,874.75, is saved. With a composition of 10% wood dust, 30% wood shavings, and 60% gorilla glue, wood ceiling planks provide a combination of strength and cost-effectiveness, making them an economical and eco-friendly building material.
