一、玻璃纤维增强水泥(简称GRC)的发展概况我国玻璃纤维增强水泥在三十年代就有试验,但大规模试用始于1958年.当时我国对玻纤的抗碱性缺乏认识,虽然大量试验,但因纤维被侵蚀,造成短期内强度丧失,因而不得不停止使用.六十年代中期,由于石棉供应紧张,有些人又开始抗碱纤维的试验研究 1. Development of glass fiber reinforced cement (abbreviated as GRC) China’s glass fiber reinforced cement was tested in the 1930s, but a large-scale trial began in 1958. At that time, China had a lack of understanding of the alkali resistance of glass fiber, although a large number of tests However, due to fiber erosion, which caused short-term loss of strength, it had to be stopped. In the mid-1960s, due to the tight supply of asbestos, some people began to study the resistance to alkali fiber.
