    济南自流平冬季施工需注意
    来源:http://www.jndmzp.com   时间:2015-12-15 17:14:42
    施工时一般需现场加清水适当搅拌后进行施工。在施工温度达到冰点时,水泥自流平施工时所需的水会结冰,自然是无法继续施工水泥自流平。那么,如果施工温度没有达到冰点,但在0度以上5度以下时,一样不能施工。这种情况与冰点是两个概念,前者是无法施工,后者是不能施工,因为在这样的温度下,水虽然不会结冰,但水泥自流平无法在正常时间范围内与水充分反应达到其应有的性能,所以若强行施工就自然留下许多后遗症。
    Construction, the general need to add water to the appropriate mixing after the construction. In the construction temperature to achieve the freezing point, the water will freeze when the cement self leveling construction, the natural is unable to continue the construction of cement self leveling. Well, if the construction temperature did not reach the freezing point, but in 0 degrees above 5 degrees below, the same can not be construction. This situation with the freezing point is the two concept, the former is unable to construction, the latter can not be constructed, because at this temperature, the water will not freeze, but the cement flow can not be fully reflected in the normal time range with water to achieve its proper performance, so if the forced construction will naturally leave many sequelae.
    水泥自流平冬季施工大的自然障碍就是温度问题。当地表温度很高时,水泥自流平一样不建议施工,原理还是一个水化反应问题,温度低是水化反应过慢,温度高是水份挥发过快,在水泥自流平与水还未及时完成反应之前,水份先挥发了,造成水份的不足,一样会产生很多质量问题。
    Cement self leveling winter construction of the biggest natural obstacle is the problem of temperature. When the surface temperature is very high, cement self leveling is not recommended for construction, principle or a hydration reaction, the temperature is too slow, the temperature is too high, the water evaporation is too fast, the water before the completion of the reaction, the water is not enough, resulting in a lot of quality problems.
