基于机械强化方法的混凝土搅拌技术研究

Research of Mechanical Methods for Improving Mixing Process of Concrete

针对混凝土搅拌过程中存在的水泥颗粒团聚和搅拌低效区问题,提出了通过改进搅拌装置结构来强化搅拌过程的3种机械强化方法:振动搅拌法、双排叶片搅拌法和综合强化法。通过对不同机械强化方法的理论分析和试验研究,分析了它们对混凝土搅拌质量和效率的影响。结果表明:振动搅拌法、双排叶片搅拌法和综合强化法均能在较短的搅拌时间内,消除水泥颗粒团聚现象和搅拌低效区的不利影响,显著提高混凝土的强度和匀质性;双排叶片法更适于工业化应用和现有设备的低成本改造。

Three mechanical methods for improving mixing process were proposed to overcome the defects of cement agglomeration and inefficient zone in mixing process of concrete.These methods were vibratory mixing,double-row blades mixing and integrated application mixing,which based on the improved structure of mixing mechanism.Through theory analysis and experimental research on various methods,the influence of these methods on mixing quality and efficiency were analyzed.The results indicated that all of mechanical ...
