Study on the Effect of Adding Nanometer Stalk Ash on the Mechanical Properties of Porous Concrete Pavement

本文主要研究了掺加纳米秸秆灰后对多孔混凝土路面性能的影响。根据抗压强度,弯曲强度和抗拉强度来测试多孔混凝土。结果表明,使用纳米秸秆灰材料极大提高了多孔混凝土路面的力学性能,其中纳米秸秆灰以10%质量分数替代水泥制备的多孔混凝土与其它比例制备的样品相比,表现出更加优异的强度;并且测试发现纳米秸秆灰多孔混凝土路面的抗压强度,弯曲强度和抗拉强度随着养护时间的增加而增加。

This paper mainly studies the influence of nano-straw ash on the performance of porous concrete pavement.Porous concrete is tested according to compressive strength,flexural strength and tensile strength.The results show that the mechanical properties of porous concrete pavement are greatly improved by the use of nano-straw ash material,and the porous concrete prepared by replacing 10%by mass nano-straw ash shows more excellent strength compared with the other samples.And the test found that the compressive strength,flexural strength and tensile strength of nano-straw ash porous concrete pavement increase with the increase of curing time.
