使用热空气进行重混凝土的热养护,以缩短养护期,这一直是一个引起怀疑的问题,因为人们认为与行之有效的蒸气养护相比,热空气养护的电能消耗比较高,混凝土强度的增长也不理想。多年来,苏联、捷克、西德等一些国家采用热空气养护隧道窑尽管取得了效果,但上述缺点仍未能通过采 The use of hot air for the thermal curing of heavy concrete to shorten the maintenance period has always been a cause for suspicion because people believe that compared with the effective steam curing, the electric energy consumption of hot air curing is relatively high and the strength of concrete increases. Not ideal. Over the years, although some countries such as the Soviet Union, the Czech Republic, and West Germany have used hot air to maintain the tunnel kiln, despite these achievements, the above-mentioned shortcomings have not yet been adopted.
