一座太阳能非补热型混凝土养护窑于1985年在中国乌鲁木齐市建成。投产使用已三年。用太阳能养护法替代寒冷地区冬季混凝土传统的蒸气养护法,提高了混凝土质量,节约大量能源,减少污染,降低成本。当冬季室外温度为摄氏零下15变至摄氏零下24度时,窑内温度为摄氏零下3度至摄氏25度。放在窑内养护的混凝土,配合使用混凝土早强剂,混凝土养护时间为30～40小时,使混凝土构件整个生产周期保持在36～
A non-thermal solar concrete curing kiln was built in 1985 in Urumqi, China. It has been put into production for three years. The solar energy conservation method is used to replace the traditional steam curing method for concrete in winter in cold areas, which improves the quality of concrete, saves a lot of energy, reduces pollution, and reduces costs. When the outdoor temperature in winter is minus 15 degrees Celsius to minus 24 degrees Celsius, the kiln temperature is minus 3 degrees Celsius to 25 degrees Celsius. Concrete kept in the kiln, with concrete early strength agent, the concrete curing time is 30-40 hours, keeping the whole production cycle of the concrete component at 36-
