基于正交试验的透水混凝土性能试验研究
|
摘要
透水混凝土是"海绵城市"建设和发展的必要材料,通过正交试验研究水灰比、粗集料粒径、目标孔隙率三个因素对透水混凝土的强度和透水性能的影响规律。结果表明,影响透水性能的主次顺序为目标孔隙率、粗集料粒径、水灰比,透水性能随着目标孔隙率、粗集料粒径的增大而增大,随着水灰比的增大而减小。影响抗压强度的主次顺序为目标孔隙率、水灰比、粗集料粒径,抗压强度随着目标孔隙率、粗集料粒径的增大而减小,随着水灰比的增大先增大后减小。
Pervious concrete is a necessary material for the construction and development of"sponge cities". The influences of water-cement ratio, coarse aggregate particle size and target porosity on the strength and permeability of pervious concrete are studied through orthogonal tests. The primary and secondary order of the results showed that the effect of permeable performance target porosity, particle size of the coarse aggregate, water cement ratio, permeable performance as the target porosity, increases with the increase of coarse aggregate particle size and decreases with the increase of water cement ratio. Affect the compressive strength of the primary and secondary order for target porosity, water cement ratio, coarse aggregate size, as the target porosity, compressive strength decreases with the increase of coarse aggregate size, after the first increases with the increase of water cement ratio decreasing.
