Use of composite materials by the construction industry is steadily increasing. Composite materials made using industrial byproducts provide a more economical use because these byproducts are inexpensive. One such material that is both abundant and inexpensive is sawdust. Several composite materials are being manufactured utilizing sawdust ttas filler material. However, the flammable nature of sawdust renders it undesirable in applications where fire hazard is a concern, such as in residential structures. This paper deals with using composite particleboards composed of sawdust and Geopolymer resin. Geopolymer, a relatively new type of inorganic resin, is known for its ease in processing and temperature resistance up to 1000°C. Prisms were made using various volume fractions of sawdust ranging from 11% to 38% by mass. The prisms were tested in compression and flexure to obtain the basic properties of the Geopolymer-sawdust particleboards. They were also strengthened with glass and carbon reinforcements to increase flexural capacity. The results indicate that it is possible to manufacture and engineer these types of composite beams to obtain a specified strength. Fire tests conducted at the FAA Technical Center show that the beams satisfy FAA fire requirements. These high-temperature performance results are presented in a separate paper.
