The Preparation and Performance of Gypsum-based Composites
Gypsum-based composites was produced using gypsum power(cement),PVA,white latex and sawdust via pouring process.The influences of water/cement ratio,PVA/cement ratio and glue/cement ratio on release time,density and impact strength of the gypsum-based composites were investigated through orthogonal experiment.The results showed that PVA strengthened obviously impact strength,and also delayed the s release time of the Gypsum-based composites.Sawdust as light filler reduced the composites density.Low content of white latex is beneficial to increase the impact strength,while high content of white latex is easy to form micelle in the gypsum crystallization process and is enclosed in crystals,which decreases the impact strength of composite materials.
