在利用太阳能养护混凝土构件方面,目前有不少地区都在进行试验,其方法大多采用箱型太阳罩,并辅以反射罩,从而获得一定的热养效果。这种方法从经济角度考虑,也是便宜的,它的主要缺点是不便保管,占用较多场地,特别是当构件起吊、搬运时,养护罩随之来往搬动,就更嫌麻烦了。我们在利用太阳能养护混凝土构件方面,从2月分以来作了以下几种方案的测试比较:①一黑一透明塑料薄膜袋充气; In the use of solar energy conservation of concrete components, there are currently many areas are conducting tests, and most of the methods use box-type solar mask, supplemented with a reflector, so as to obtain a certain thermal effect. This method is also economical, and it is also cheap. Its main drawback is inconvenience to custody and it occupies more space. Especially when the components are hoisted and transported, the protective cover is moved along and it is even more troublesome. In terms of using solar energy to preserve concrete components, we have compared and tested the following solutions since February: 1. A black-and-transparent plastic film bag is inflated;
