摘要：By using orthogonal experiment styrene-acrylic cement composite material (SCCM) was designed and prepared, its tensile mechanical properties were tested and analyzed. The results indicate that powder-liquid ratio determines the curing reaction forms of SCCM, which is the main factor influencing tensile mechanical property of SCCM. When powder-liquid ratio is low (0.45), the deformation performance and tenacity of SCCM are declined with the increase of cement content. When powder-liquid ratio is high (0.65, 0.85), the strength, deformation performance and tenacity of SCCM are increased with the increase of cement content, furthermore, the increase of performance will be more obvious if the powder-liquid ratio is higher. Talcum powder can improve the strength of SCCM while heavy calcium carbonate can improve its deformation performance and tenacity. When the powder-liquid ratio is 0.65, the cement content is 0.35, the packing type is heavy calcium carbonate, the tensile mechanical properties of SCCM are better, which has a great potential to be used as a building joint material.
