The Effect of Coupling Agent on Mechanical Properties of Durafiber Reinforced Furan Resin Mortar ZENG Hai yan,YAN Shi lin,ZHANG Hong qi (School of Sciences, Wuhan University of Technology, Wuhan 430070,China)The changes of mechanical properties of furan resin mortar in two cases were studied. One case was the furan resin mortar was mixed with Durafiber of variable volume fractions. In the other case, the durafibers were pretreated by variable silane coupling agents. The experiment results indicated that durafiber could only increased the tension strength and flexure strength of furan resin mortar by a little. While durafiber pretreated by silane coupling agent can enhance the strengths greatly and with a little decrease in the compression strength.silane coupling; durafiber; furan resin; mechanical properties
