采用热拌混凝土有以下几个目的:从整个工艺循环中缩短或者取消升温期(3～5小时或更多),从而缩短混凝土在模板中的硬化期限;完全地或部分地消除混凝土在传统养护方法中主要是升温期出现的使后期强度降低的结构破坏现象;通过对拌和物在拌制过程中直接加热,降低热养护的能量消耗;由于生产周期的缩短使模板数量、生产面积等相对减少而降低生产成本。近年来,国外对热拌混凝土的研究仍在继续进行。研究的重点多在热拌混凝土本身的物
The use of hot mix concrete has the following purposes: shorten or cancel the temperature increase period (3 to 5 hours or more) from the entire process cycle, thereby shortening the hardening period of the concrete in the formwork; completely or partially eliminating the concrete in the conventional curing The main method is the structural failure phenomenon that causes the late strength to decrease during the temperature rising period; by directly heating the mix during the mixing process, the energy consumption for heat conservation is reduced; and the number of templates and the production area are relatively reduced due to the shortening of the production cycle. And reduce production costs. In recent years, research on hot-mixed concrete has continued in foreign countries. The focus of research is on the contents of hot mix concrete itself.
