一、前言自1966年7月英国公布了马江姆达(Majumdar)发明的抗碱玻纤的专利以来,玻璃纤维增强水泥(以下简称 GRC)就进入了一个新的发展时期。由于 GRC 强度高,韧性好,可制成表面丰富多彩的薄壁制品和构件,因此,近二十年来,GRC 作为一种独特的新型建筑材料,打入了几十个国家和地区的建筑市场,五百多家公司取得了制造 GRC 制品的许可证。1975年,在英国召开了第一届国际聚合物混凝土学术会议。据报道,英国规定用抗碱玻纤与普通硅酸盐水泥匹配得到的 GRC,只能制作非承重构件和一些建筑小品。其根本原因是赛姆菲尔(Cemfil)抗碱玻纤还不足以抵抗高碱性硅酸盐水泥中氢氧化钙的强
I. INTRODUCTION Since the publication of the patent for alkali-resistant fiberglass invented by Majumdar in July 1966, glass fiber reinforced cement (GRC) has entered a new period of development. Due to its high strength and toughness, GRC can be used to make thin-walled products and components with a variety of surfaces. Therefore, GRC as a unique new building material has entered the construction market in dozens of countries and regions for nearly two decades. More than 500 companies have obtained licenses to manufacture GRC products. In 1975, the first International Conference on Polymer Concrete was held in England. It has been reported that the UK has established that GRC obtained by matching alkali-resistant glass fiber with ordinary portland cement can only produce non-load-bearing components and some architectural skits. The underlying reason is that Cemfil alkali-resistant glass fiber is not enough to resist the strong calcium hydroxide in the high-alkaline portland cement.
