混杂纤维自密实混凝土孔结构对抗压强度影响的试验研究OA北大核心CSCDCSTPCD
Experimental Study on the Influence of Pore Structure of Hybrid Fibers Self-compacting Concrete on Compressive Strength
采用压汞法对混杂纤维自密实混凝土进行微观孔结构试验,并进行抗压强度试验,分析了混杂纤维自密实混凝土孔结构的孔隙率、孔径尺寸与级配、孔分布特征与强度的关系,得出混杂纤维自密实混凝土孔结构与抗压强度的关系趋势.研究结果表明,在自密实混凝土中混杂掺人玄武岩纤维和聚丙烯纤维,其微观孔结构的改善对抗压强度的提高有着直接的影响.
This research used the method of mercury injection to test micro pore structure for mixed basalt fiber and polypropylene fiber of self-compacting concrete, tested the compressive strength of each specimen,and analyzed the hybrid fibers of self-compacting concrete with the pore structure of porosity, pore size and gradation,pore distribution characteristics and the relationship of the strength,then get the relationship between hybrid fiber of self-compacting …查看全部>>
