骨料浆体厚度对混凝土抗压强度的影响

Effect of average paste thickness on coated aggregates on mechanical properties of concrete

通过采取不同技术措施改变骨料浆体平均厚度,研究了其与混凝土力学性能的关系,并力图寻找一种新的配合比调整路线和预拌混凝土质量稳定性控制方法。定义的浆体中包括0.08 mm以下的颗粒,这对科学合理使用石粉含量较高的人工砂、尾矿砂等替代资源提供了新的技术思路和应用途径。

The relationship between the average paste thickness on coated aggregates and the mechanical properties of concrete is studied by adopting different technical measures,and a new method of mix proportion adjustment and quality stability control of premixed concrete are sought.The paste defined in this paper includes materials finer than 0.08 mm,which provides a new technical guidance and application approach for scientific and reasonable use of manufactured sand,tailing sand and other alternative resources with high content of rock fine.
