Abstract:The effect of material constituents on the performance of fiber reinforced cementitious thin sheets was studied in order to examine the possible trade-off between cost and performance in cement-based building product development. A variety of materials were incorporated into fabricating cementitious thin sheets. The variables included types of fibers (glass, polyethylene terephthalate, polyolefin, or polyvinyl alcohol), types of sand (marble, silica or fly ash) and percent content, mixing method (dispersive or non-dispersive), latex types (MMA or SB), cement types (Type I or Type III), mineral additives (metakaolin or silica fume) and curing conditions (moisture or steam). Twelve batches of thin sheets with 3% fibers by volume for each were prepared by extrusion processing and three-point bending tests were conducted to evaluate the strength and toughness. The purpose of the study was to establish several mix designs for extrusion production of high performance fiber reinforced cementitious thin sheets at compatible cost.
