一种在水利护岸工程中可代替混凝土和浆砌块石的新型建筑材料——纤维水泥砂土,经过有关科技人员两年多的研制,已经获得成功,日前通过有关部门鉴定。纤维水泥砂土是由纤维、水泥、砂、土及水按一定的配合比和先进的工艺配制而成的。纤维的作用主要是增强材料的抗拉、抗裂和耐久性能,水泥和砂在纤维水泥砂土中作为胶凝剂和细骨料,摻入的粘土或亚粘土,即能改善材料在拌和中的和易性,又能作为胶凝剂,节约水泥、降低造价。这种新型的建筑料材不仅具有一定的防冲、防 A new type of building material that can replace concrete and masonry stone in water conservancy bank protection project - fiber cement-sand, has been successfully researched and developed by relevant departments after more than two years’ development by scientific and technical personnel. Fiber cement sand is made of fiber, cement, sand, soil and water by a certain ratio and advanced technology prepared. The role of the fiber is mainly to enhance the tensile, cracking and durability properties of the cement and sand in the fiber cement sand as a gelling agent and fine aggregate, clay or loam incorporation, which can improve the material in the mixing The workability, but also as a gelling agent, saving cement, reduce costs. This new type of construction material not only has some anti-red, anti-
