针对传统混凝土搅拌工艺中存在的问题,讨论先拌水泥砂浆法、先拌水泥净浆法、水泥裹砂法、水泥裹石法及粗细骨料全造壳法等二次搅拌工艺所具有的不同工艺流程对混凝土搅拌质量的影响,测试不同条件下混凝土的匀质性、抗压强度指标,并与传统搅拌工艺进行对比试验。结果表明:二次搅拌工艺较传统搅拌工艺能明显提高混凝土的搅拌质量和效率,改善混凝土界面过渡区的黏结强度。 In view of the existing problems in the traditional concrete mixing process, the differences between the two mixing processes such as the first mixed cement mortar method, the first mixed cement mortar method, the cement-wrapped sand method, the cement-coated stone method and the coarse and fine aggregate all- The influence of process flow on the quality of concrete mixing was tested. The homogeneity and compressive strength index of concrete under different conditions were tested and compared with the traditional mixing process. The results show that the second mixing process can significantly improve the mixing quality and efficiency of concrete, and improve the bond strength of the transition zone of concrete compared with the traditional mixing process.
