1990年9月在布拉格召开的第五届砼会议上,英国介绍了纤维加强水泥砼、聚合物砼和高强砼的研制情况。常用于加强水泥和砼的纤维分为两类,一是聚丙烯、聚乙烯等低弹模和高延伸率纤维,主要是增强韧性;一是钢、玻璃、石棉和碳纤维等高弹模和高强度纤维,构成强的组合物,但耐久性仍然是主要问题。聚合物砼包括聚合物浸渍砼和聚合物波特兰水泥砼, At the Fifth Concrete Conference held in Prague in September 1990, the United Kingdom introduced the development of fiber reinforced concrete, polymer concrete and high strength concrete. Commonly used to strengthen the cement and concrete fibers are divided into two categories, one polypropylene, polyethylene and other low elastic modulus and high elongation fibers, mainly to enhance the toughness; First, steel, glass, asbestos and carbon fiber and other high modulus and high Strength fibers, make up strong compositions, but durability remains the major issue. Polymer concrete includes polymer impregnated concrete and polymer Portland cement concrete,
