喷射砼作为矿山、交通、水利、工业与民用建筑以及国防工程的支护结构材料,以它简便的工艺、独特的性能、经济的造价以及广泛的用途等优点,在各个相关领域里显示出强大的生命力。纤维喷射砼技术是80年代在普通喷射砼基础上发展起来的一种新的施工技术。该技术是在普通喷射砼中加入钢纤维或化学纤维而形成的复合材料。它克服了普通喷射砼脆性的弱点,具有高强度、大变形及
As a supporting structure material for mining, transportation, water conservancy, industrial and civil buildings and national defense engineering, jetting concrete shows its advantages in various related fields due to its advantages of simple process, unique performance, economical cost and wide range of uses Vitality Fiber jetting concrete technology is a new construction technology developed on the basis of ordinary jetting concrete in the 1980s. This technique is a composite material formed by adding steel fibers or chemical fibers to ordinary jetted concrete. It overcomes the weakness of ordinary jet concrete brittleness, with high strength, large deformation and
