废弃混凝土充填复垦材料性能的试验研究

Experimental Study on Performance of Filling Reclamation Materials of Waste Concrete

为了揭示不同骨料组成对废弃混凝土充填复垦材料性能的影响,分别测定了黄土、经二级破碎后的废弃混凝土、0~5 mm废弃混凝土、5~16 mm废弃混凝土、粒径>16 mm废弃混凝土及二级破碎废弃混凝土与黄土以1:1的质量比均匀混合的拌合物的堆积密度及饱和含水率,并综合选取最佳组成的原材料进行相似模拟试验测试其持水性能。

In order to reveal the influences of different aggregate of the waste concrete on the performance of filling reclamation materials, the stacking density and the saturated moisture content of the loess, the secondary crushing of waste concrete, waste concrete 0~5 mm in diameter, waste concrete5~16 mm in diameter, waste concrete particle size greater than 16 mm,and the mixing mixture of the secondary crushing of waste concrete and the loess with weight ratio of 1:1 are determined,what′ s more,the best compositions is simulated by similarity simulation experiment to test the water holding capacity of filling reclamation materials.
