建筑废料制备生态护坡复合材料及其基本性能

Preparation of ecological revetment composite materials with construction waste and its basic properties

以建筑废料为主要原材料制备了生态护坡复合材料。研究了水灰比、硅灰掺量、集料粒径级配、减水剂掺量对生态护坡复合材料力学性能和透水性能的影响。研究表明:护坡材料最佳配合比为水灰比0.28、硅灰掺量5%、集料粒经级配3∶1和减水剂掺量1%;硅灰的加入能改善生态护坡复合材料拌合物的和易性和提高材料的力学性能。

Preparation of ecological revetment composite materials with construction waste as main raw material.The effect of mechani-cal properties and permeability properties of the ecological revetment composite materials ,which studied on the water-cement ratio and sil-ica fume,and the particle size of recycled concrete aggregate,and reducing agent.The research results showed that the best mix ratio of e-cological revetment composite materials was water-cement ratio 0.28 and silica fume content 5%,and the particle size of recycled concrete aggregate was 3∶1,and reducing agent content 1%;Silica fume have plays a crucial role,which the improvement of mechanical properties of ecological revetment composite materials.
