日本三井建设会社已研制成功阿拉米德纤维水泥,不仅重量轻而且强度高,成为一种新型的建筑材料。阿拉米德纤维是美国出产的一种高强力纤维,在这种纤维中混入水泥,就形成阿拉米德纤维强化水泥,可用射出成型机连续生产。由于长短两种纤维的力量在内部交错牵制,因而这种纤维水泥具有与钢筋相同的强度。这种水泥即将进入实有化阶段,为不使 Mitsui Construction Co., Ltd. has successfully developed Aramid fiber cement, which is not only light weight but also high in strength and has become a new type of building material. Allamide fiber is a kind of high-strength fiber produced in the United States. The fiber is mixed with cement to form Aramid fiber-reinforced cement, which can be continuously produced by an injection molding machine. Since the strength of the two fibers is staggered internally, the fiber cement has the same strength as the reinforcing steel. This kind of cement is about to enter the stage of
