根据现行的混凝土抗压试验办法,混凝土的抗压强度,到28天后才能正确地知道;当然国内外也有用蒸汽养生的试块在24小时后能判断混凝抗压强度的方法,以及其他的鉴定方法,可以缩短时间便于早日知道混凝土质量情况。
According to the current concrete compression test method, the compressive strength of concrete can only be known correctly after 28 days; of course, domestic and foreign methods that can also determine the compressive strength of coagulation after the steam healthy test block can be used as well as other methods. The identification method can shorten the time and make it easier to know the quality of the concrete as soon as possible.
