日本首次建成１３０Ｎ／ｍｍ~２超高强度混凝土地下连续墙日本大林组开发的设计标准强度为１１０Ｎ／ｍｍ２的超高强度混凝土地下连续培，现在已用于构造物的基础施工，最近又在建筑领域内开发出设计强度为１３０Ｎ／ｍｍ’的超高强度混凝土。设计标准强度超过６０Ｎ／ｍ?.. For the first time in Japan, a 130N/mm~2 ultra-high-strength concrete underground continuous wall developed by the Japanese Daelim Group has been designed for the development of ultra-high-strength concrete underground continuous concrete with a design standard strength of 110 N/mm2. Now it has been used for the foundation construction of structures, and recently in construction. In the field, ultra-high-strength concrete with a design strength of 130 N/mm’ has been developed. Design standard strength exceeds 60N/m?..
