我国水泥新标准实施以来,有些单位来信反映,他们生产或使用的某些水泥,在进行强度检验时,采用新标准规定的水灰比将难于成型,因而也无法正确测定这些水泥的强度。据我们了解,这种现象虽属少数,但确实存在,是我国水泥新标准中急待改进的地方。 Since the implementation of the new cement standard in our country, some units have written letters that some of the cement they produce or use will be difficult to shape by the water-cement ratio stipulated by the new standard when conducting strength testing. Therefore, the strength of these cements can not be correctly determined. According to our understanding, although this phenomenon is a minority, it does exist and is an urgent need for improvement in the new cement standard in our country.
