| 摘 要： | 文章基于掺磷渣粉的全级配混凝土试验,研究全级配混凝土的成型养护方法及变形性能,并与湿筛小试件的性能进行比较.结果表明:全级配混凝土大试件的抗压弹模比湿筛小试件高;大骨料的存在对泊松比影响不如对极限拉伸性能的影响那么明显;大试件自生体积变形规律与湿筛试件略有不同;大试件干结值与徐变都低于湿筛试件的结果.

| Abstract: | Based on the test of full-graded concrete with phosphorus slag powder,the molding,curing and deformation properties of full-graded concrete is studied and compared with the small wet-screened specimen. The results show that the compressive elastic modulus of large specimen is larger than that of small specimen; the influence of large aggregate on Poisson's ratio is less remarkable than on ultimate tensile value;large specimen autogenetic volumetric deformation is different from the small specimen; dry shrin... |
