摘要：研究了硅灰掺量（0、6%、16%、26%、36%、46%）对多孔混凝土抗压强度、孔隙率、孔隙溶液pH值和植生性能的影响，并进行了微观分析。结果表明：随着硅灰掺量的增加，多孔混凝土的28 d、56 d抗压强度基本呈先增大后降低再增大的趋势，孔隙率、孔隙溶液pH值均呈降低趋势；适量硅灰的掺入提高了15 d、30 d植株高度和叶片含水率；适量硅灰能提高体系的水化程度和基体密实度，过量硅灰反而会降低基体的密实度。 Abstract：The effects of content of silica fume(0, 6%, 16%, 26%, 36%, 46%) on the compressive strength, porosity, the pH value of the pore solution and planting performance of porous concrete were investigated, and microscopic analysis was carried out. The results show that, with the increase of the content of silica fume, the 28 d and 56 d compressive strengths of porous concrete basically show the trend of first increasing then decreasing and further increasing, the porosity and the pH value of the pore solution of porous concrete all show the trend of decreasing. Appropriate content of silica fume increases the height of plants and the water content of leaves at 15 d and 30 d. Appropriate content of silica fume can improve the hydration degree of the system and matrix compactness, while excessive silica fume may decrease the compactness of the matrix.

Abstract：The effects of content of silica fume(0, 6%, 16%, 26%, 36%, 46%) on the compressive strength, porosity, the pH value of the pore solution and planting performance of porous concrete were investigated, and microscopic analysis was carried out. The results show that, with the increase of the content of silica fume, the 28 d and 56 d compressive strengths of porous concrete basically show the trend of first increasing then decreasing and further increasing, the porosity and the pH value of the pore solution of porous concrete all show the trend of decreasing. Appropriate content of silica fume increases the height of plants and the water content of leaves at 15 d and 30 d. Appropriate content of silica fume can improve the hydration degree of the system and matrix compactness, while excessive silica fume may decrease the compactness of the matrix.
