采矿和地下作业条件非常艰苦,支撑框架的安装也不容易,安装支撑框架需要使用混凝土,GRC能适应这样的严酷条件,而且能装配成各种形状和尺寸的支撑框架。GRC在养护期间能形成保护混凝土的光滑致密的表面,由于GRC结构致密和其水泥含量高,耐地层化学物质和矿物水侵蚀的稳定性与优质混凝土一样好。GRC的优点有:①不仅能在地面上装配简单的骨架,而且还能组装成复杂的形状。②GRC是预制混凝土,与钢材相比,重量较轻。③材料对健康无害,本身不腐烂,抗腐蚀,不怕虫蛀。④GRC不燃烧,不爆炸。⑤能作成平坦且耐磨的表面,防止空气和瓦斯的渗漏。⑥GRC还可用作钢筋混凝土以及低质或喷射混凝土的优质保护面层。
Mining and underground working conditions are very difficult. The installation of supporting frames is not easy. The installation of supporting frames requires the use of concrete. GRC can adapt to such harsh conditions and can be assembled into supporting frames of various shapes and sizes. GRC can form a smooth, dense surface that protects concrete during curing. Due to the compact structure of GRC and its high cement content, the stability of formation-resistant chemicals and mineral water erosion is as good as that of high-quality concrete. The advantages of GRC are: 1 Not only can a simple skeleton be assembled on the ground, but it can also be assembled into complex shapes. 2GRC is precast concrete and lighter than steel. 3 The material is harmless to health and does not rot, resist corrosion, and is not afraid of insects. 4GRC does not burn and does not explode. 5 can make a flat and wear-resistant surface to prevent leakage of air and gas. 6GRC can also be used as a high-quality protective surface for reinforced concrete as well as low quality or shotcrete.
