大流动性混凝土是近几年来发展起来的新型混凝土。同工业发达的国家相比,这种新型混凝土在我国的实践经验还不多。1981年,我们在一项由国外担任设计的工程中试用了这种新型混凝土。该工程为现浇钢筋混凝土板、梁、柱延性框架结构,混凝土工程总量约五万立方米。本工程的混凝土设计有两个特点。其一是除地下 High-flow concrete is a new type of concrete developed in recent years. Compared with industrially developed countries, this new type of concrete has little practical experience in China. In 1981, we tried this new concrete in a project that was designed as a foreign company. The project is a cast-in-place reinforced concrete slab, beam, and column ductile frame structure with a total of about 50,000 cubic meters of concrete. The concrete design of this project has two features. One is to remove underground
