第三讲:碾压混凝土的材料 碾压混凝土筑坝技术首要问题是混凝土配合比设计。碾压混凝土虽是干硬性的,但这绝不是减少水的用量,必须是在满足施工和设计要求的前提下,尽可能地节约胶凝材料,以达到降低水化热、简化温控和加速施工之目的。碾压混凝土配合比设计,已有不少专门论述,原则上与常态混凝土配合比设计方法相同。主要在于确定水与胶凝材料、水泥浆与细骨料、细骨料与粗骨料之间的关系。更科学、更简便的方法,有待进一步研究。
Lecture 3: RCC Materials RCC dam construction The primary problem is the concrete mix design. Although RCC is dry and hard, it is by no means to reduce the amount of water used. It must be possible to save as much gelling material as possible in order to meet the requirements of construction and design in order to reduce heat of hydration, simplify temperature control and speed up The purpose of construction. RCC mix design, there have been many specialized discussion, in principle, with the normal design method of concrete mix the same. Mainly to determine the relationship between water and cementitious materials, grout and fine aggregate, fine aggregate and coarse aggregate. A more scientific and easier way to be further studied.
