Abstract/Executive Summary

Cement production is one of the most mass-produced industrial processes worldwide and a major contributor to global CO2 emissions, driving the search for sustainable alternatives in construction materials. Fiber cement boards are widely used for cladding, roofing, and partitions; however, their production remains energy-intensive and environmentally demanding. This study explored the development of eco-friendly and sustainable fiber cement boards by incorporating cogon grass fiber (CGF), regarded as an invasive plant, fly ash (FA), and quail eggshell (QE) waste, both of which contribute to landfill waste. The researchers aimed to reduce environmental impact while maintaining durability and mechanical strength for indoor partition applications. Using an experimental-developmental approach, fiber cement board samples were produced with varying cogon grass fiber contents (5%, 10%, 15%) and a fixed 70:30 ratio of FA to calcined QEP, mixed, molded, cured for 28 days, and tested for mechanical properties in accordance with ASTM standards, including compressive strength (CS) to determine the structural load-bearing capacity, flexural strength (FS) to assess the board's bending performance, water absorption (WA) to quantify the suitability for high-moisture environments, and a drilling test (DT) to examine both the material's workability and structural integrity during installation performance. An environmental impact assessment was conducted using OpenLCA software. Results showed that CS results demonstrated adequate load resistance for non-load-bearing applications; the 10% fiber sample achieved an FS of 3.83-5.6 MPa, exceeding the 4 MPa minimum for Grade 1 Classification, while WA values remained within acceptable limits for FCB. Drill test results confirmed satisfactory workability.
