Increase in need of housing unit in the Philippines meant increase in cement manufacture. As the population tremendously grow, the possibility that the source of cement may one day be depleted is at hand. Researchers now focus on finding ways to reduce manufacture of cement by producing sustainable construction materials utilizing alternatives for replacement of cement. The purpose of this study is to investigate the property characterization of cement bonded particle board (CPB) using scoria as partial replacement to cement. Laboratory size CPBs with dimensions of 1.25 x 30 x 30 cm were produced using cement: falcata particles ratio of 60/40 and scoria content as cement replacement of 0%SC, 5%SC, 10%SC, 15%SC, 20%SC, 25%SC, 30%SC and 35%SC. The falcata particles collected were hamermilled and soaked in water for 24 hours then air-dried in equilibrium moisture content. Cement and water were mixed with the particles until thoroughly coated with cement. The mixtures were mat formed, pressed and clamped for 24 hours. After the boards were cured and conditioned for 28 days, the boards were tested for their mechanical and physical properties and compared with control specimen (0%SC). The physical properties of boards gave remarkable result for all set with scoria replacements such that the least TS is at 0.15% while 12.33% in WA. For the mechanical properties, MOR of scoria replacements of 20%SC and 25%SC produced boards exceeding PNS/CTP 07 (1990) standard for non-structural 12 mm thick boards of 6.75 MPa. Also, the recorded maximum load resistance in NPT is at 121.55 kgf (1.19 kN) at 35%SC replacement. The results showed that the properties of the boards were influenced by the amount of scoria put in replacement to cement. Also 20%SC replacement produced good quality boards by satisfying the minimum requirements of PNS/CTP 07:1990 and exceeding performance requirements from commercial plants.
