预填骨料混凝土配制方法探究

RESEARCH ON PREPARATION METHOD OF PREFILLED AGGREGATE CONCRETE

各类混凝土具有不同的配制方法。基于预填骨料混凝土的特性,采用体积法,提出预填骨料混凝土的配制方法。通过试验验证,采用该方法配制的预填骨料混凝土满足配制要求。在保证浆体流动性的前提下,可以通过掺入矿物掺合料或细砂的方式提高预填骨料混凝土的抗压强度以及拌合物的表观密度。

Various types of concrete have different preparation methods. Based on the characteristics of prefilled aggregate concrete, this paper proposes the preparation method of prefilled aggregate concrete by volume method. Through experimental verification, the prefilled aggregate concrete prepared by this method meets the preparation requirements. On the premise of ensuring the fluidity of the slurry, the compressive strength of the prefilled aggregate concrete and the apparent density of the mixture can be improved by adding mineral admixtures or fine sand.
