一、前言随着“GRC”工业的不断发展,“GRC”的耐久性将成为生产中的关键问题。而“GRC”耐久性的确定主要靠水泥对玻璃纤维的侵蚀速率。水泥对玻璃纤维侵蚀的试验方法,从50—60年代“GRC”诞生起,就有好几种,但是,至今仍没有一个同一标准。不过,从发展趋势 I. INTRODUCTION With the continuous development of the “GRC” industry, the durability of “GRC” will become a key issue in production. The determination of the durability of “GRC” depends mainly on the erosion rate of glass fiber by cement. There are several test methods for the erosion of glass fibers by cement from the birth of GRC in the 50s-60s. However, there is still not a single standard. However, from the development trend
