摘要
在进行混凝土配合比试验时,发现混凝土早期强度正常,但后期强度增长很少。利用正交对比试验,分析了各种材料对强度的影响,找出了粉煤灰是影响后期强度增长不正常的主要因素,最终解决了配合比设计问题。
In the concrete mix test, it is found that the early strength of concrete is normal, but the strength of the later stage is very little. By using the orthogonal contrast test, the influence of various materials on the strength is analyzed. It is found that the fly ash is the main factor affecting the abnormal growth of the later stage, and finally the problem of the mix design is solved.
