摘    要:将无沙大孔生态植被混凝土应用到水利护坡工程建设中,可以使混凝土与自然生态和谐相处.在无沙大孔生态混凝土配合技术试验的基础上,增加粉煤灰、减水剂等,研究其对混凝土性能的影响,结果表明:随着粉煤灰掺量的增大,沉浆厚度和沉浆面积先增大后减小;减水剂掺量越大,混凝土沉浆面积和沉浆厚度相应增大;减水剂、粉煤灰对无沙大孔混凝土强度影响不明显.

关 键 词:生态混凝土  粉煤灰  减水剂  空隙率  沉浆面积

Abstract:The relationship between concrete and natural ecology are harmonized when no-fine ecological concrete was applied in hydraulic engineering construction for slope protection engineering construction.Based on the research of compounding technique of no-fine ecological concrete,fly ash and water reducing admixture are increased in order to research their influence to the performance of concrete.The result shows that with increase of the dosage of fly ash,sediment paste depth and area first increase,and then de...
Keywords:ecological concrete  fly ash  water reducing admixture  void ratio  sediment paste area
