石灰石粉对混凝土性能影响研究

Study on effect of grinding limestone powder on concrete properties

石灰石矿山生产机制砂和碎石会产生石灰石碎屑,本文将石灰石碎屑用实验室小磨粉磨不同时间,得到不同细度的石灰石粉,将试验得到的石灰石粉样品按不同比例替代粉煤灰,进行混凝土试验,检测其对混凝土性能的影响,以期合理应用于混凝土中.

Limestone mines produce limestone debris when they produce machine-made sand and gravel.In this paper,different fineness of limestone powder was obtained by grinding limestone debris with laboratory small mill grind for different time.The limestone powder samples obtained from the test were substituted for fly ash in different proportions to carry out concrete tests to detect its influence on concrete performance,so as to reasonably apply in concrete.
