高含泥量集料对混凝土性能的影响及有效对策分析

Analysis on Influence of High Silt Content Aggregate on Concrete Performance and Its Effective Countermeasures

混凝土性能受多种因素影响,其中高含泥量集料是影响混凝土性能最关键的因素。高含泥量影响混凝土性能的主要原因是高效减水剂对水泥的成分具有吸附功能,最终增加混凝土的坍落度,影响混凝土的强度。因此,建筑人员在工程建设过程中要重视集料的含泥量问题,控制其含泥量以提升混凝土性能。对此,从高含泥量集料对混凝土性能影响的具体表现、提高混凝土性能的具体对策这两个方面进行阐述,为提升混凝土的性能提供合理的参考意见。

The concrete performance is impacted by many factors, in which the high silt content aggregate is the most key factor to impact the concrete performance. The main reason of high silt content to impact the concrete performance is the high efficient slushing agent having the adsorption function to composition of cement, finally increasing the slump of concrete and impacting the strength of concrete. Therefore, the constructors should pay attention to the silt content of aggregate in the engineering construction, and control its silt content to improve the concrete performance. The article sets forth the detailed influence of high silt content aggregate on concrete performance and the detailed countermeasures to improve the concrete performance, which can be referred for the improvement of concrete performance.
