摘要

本文主要是探討在不飽和聚酯樹脂無水混凝土中加入玻纖改良後之物性的變化;由於傳統水泥砂漿結構皆為多孔脆性且抗彎強度低,因此加入玻璃纖維及不飽和眾酯樹脂去改善這些缺點,並增加其耐久性及密緻性。本實 驗主要是以不飽和聚酯樹脂取代水泥砂漿中的水,增加材料的黏結性及抗張性;玻璃纖維則是作為強化材,以增加水泥漿體的韌性及抗彎、抗拉等機械性質。由實驗結果得知,玻纖的添加對試體在抗壓、抗彎及抗拉有一定程度的提升。但由於不飽和眾酯樹脂較黏綢,使得材料整體的工作度和流度下降。

The change on physical property of glass fiber reinforced unsaturated polymer modified cement without water is mainly investigated in this article. The microstructure of traditional cement is often holey and has low flexural strength so glass fiber and unsaturated polymer is introduced into the cement to improve those shortcomings and to increase durability and water tightness. Water was replaced by the unsaturated polymer in this experiment in order to raise coherence and tensibility in compound material. Glass fiber is used to reinforce material for increasing toughness, flexural strength, and tensibility in unsaturated polymer modified concrete. The results indicate that the adding of glass fiber can promote the strength of compression, flexure, and tension but the workability and fluidity is getting worse. The coherence of unsaturated polymer is the prime reason for that.
