| 摘 要： | 为检测外掺的氧化镁膨胀剂在混凝土中分布的均匀性,文中介绍了化学法和物理法。研究结果表明,两种方法的检测精度可靠,结论一致;只要混凝土拌和系统工作正常,在无需改变也不影响混凝土正常生产流程的前提下,采用从拌和机口外掺氧化镁膨胀剂的方式,是完全可以做到氧化镁在混凝土中均匀分布的。

| Abstract: | To measure the uniformity of MgO expanding agent in concrete,chemical and physical method are introduced in this paper.The results show that the detecting precision of the two methods is reliable and their conclusions are consistent. Besides,in the circumstances of either no need changing or influencing the normal production process of the concrete,using the method of adding MgO expanding agent at the orifice of the mixer,the MgO expanding agent can uniformly distribute in concrete. |
