混凝土泵送,concrete pumping
1)concrete pumping混凝土泵送
1.In order to solve the abrasion ofconcrete pumping system under the condition of multiphase fluid which is highly nonlinear and non-continuous,an analytical method named the quasi-non-continuous flow numerical simulation was put forward,in which the incompressible ideal gas,calcium sulfate and calcium sulfide are used to simulate the multiphase flow inconcrete pumping pipe.为了解决混凝土泵送系统中弯管极易磨损破坏的问题,针对混凝土泵送弯管内的非连续多相流体解析的强非线性和非连续性特征,提出拟非连续流数值模拟的解析方法,即对组成物质采用物理性质相近的不可压缩理想气体、calcium-sulfate和calcium-sulfide分别模拟混凝土中多相流体,各相拥有各自的动量方程和连续方程求解,相间通过压力相、体积分数和液面交换系数实现耦合。

泵送混凝土分子式：CAS号：性质：可用混凝土泵通过管道输送拌和物的混凝土。要求其流动性好，骨料粒径一般不大于管径的四分之一，需加入防止混凝土拌合物在泵送管道中离析和堵塞的泵送剂，以及使混凝土拌和物能在泵压下顺利通行的外加剂，减水剂、塑化剂、加气剂以及增稠剂等均可用作泵送剂。加入适量的混合材料(如粉煤灰等)，可避免混凝土施工中拌和料分层离析、泌水和堵塞输送管道。
