混凝土不仅经济,而且性能良好,目前已成为世界上最重要的建筑材料。普通混凝土适于整体高强结构,建造高层建筑的框架。而低层建筑、非承重结构或维护结构,并不要求普通混凝土所具有的全部性能。因此,可以与其它材料配合使混凝土能根据需要而具有相应的性能。芬兰技术研究中心研制出一种谦价的结构材料——值物纤维混凝土。该混凝土既可机 Concrete is not only economical but also has good performance. It has now become the most important building material in the world. Ordinary concrete is suitable for an overall high-strength structure and is a framework for building high-rise buildings. Low-rise buildings, non-load-bearing structures or maintenance structures do not require the full performance of ordinary concrete. Therefore, it can cooperate with other materials so that the concrete can have corresponding performance according to need. The Finnish Technical Research Center has developed a cost-effective structural material - valued fiber reinforced concrete. The concrete can be machined
