一、概述混凝土二次投料搅拌方法是一种新工艺,又可称为造壳混凝土;该法施工工艺简便易行,和常规搅拌工艺相比,不需增加任何设备,只是改变一下投料顺序就能达到节约水泥、提高混凝上强度及改善混凝土性能的目的。因此,积极推广和采用混凝土二次投料搅拌新工艺有着实际技术、经济的现实
I. Overview Concrete secondary feeding and stirring method is a new process, which can also be called shell-forming concrete. The construction process is simple and easy. Compared with the conventional mixing process, there is no need to add any equipment, just change the order of feeding. It can achieve the purpose of saving cement, increasing the strength of concrete, and improving the performance of concrete. Therefore, it is practical and economical to actively promote and adopt a new process for concrete secondary stirring.
