某工程正在紧张进行框架混凝土浇筑施工,然而泵送混凝土时却发生了多处堵管事故,为了引起重视并在以后减少和避免发生堵管现象,公司决定组织现场技术人员学习泵送混凝土的有关知识。一、泵送意义及要求用混凝土泵和输送管道输送混凝土拌合物称为混凝土泵送。混凝土能否顺利无阻地泵送,主要取决于所供应的混凝土拌合物性质。影响混凝土可泵性的因素很多且非常复杂。二、泵送影响因素 A project is under intense concrete frame construction, however, there were multiple blockage accidents when pumping concrete. In order to draw attention and reduce and avoid plugging in the future, the company decided to organize field technicians to learn about pumping concrete know how. First, the meaning and requirements of pumping Concrete pumps and pipes conveying concrete mixture called concrete pump. The smooth and unimpeded pumping of concrete depends largely on the nature of the concrete mixes supplied. The factors that affect the pumpability of concrete are many and complex. Second, pumping factors
