美国得克萨斯商业塔75层建筑物的竣工,使用了将近71872m~3的现浇混凝土,其中35%用的是高强混凝土,并且考虑了对粉煤灰的有效使用,在使用高强混凝土的地方,由于采用 C 类粉煤灰的经验有限。为了测定粉煤灰这种材料的性质与实用的配比方案,我们对粉煤灰进行了深入细致的研究与试验,这里刊登了大量的实验结果以及施工期间所使用的粉煤灰拌合物。 The completion of the 75-story building of the Texas Commercial Tower in the United States used nearly 1,872,73 m 3 of cast-in-place concrete, of which 35% used high-strength concrete and considered the effective use of fly ash, where high-strength concrete was used, due to The use of Class C fly ash has limited experience. In order to determine the properties of fly ash and the practical ratio of fly ash, we have conducted meticulous research and tests on fly ash. We have published a large number of experimental results and the use of fly ash blends during construction. .
