试验研究掺磷渣粉全级配混凝土的力学、变形及抗渗性能，并与湿筛混凝土进行对比，期望为理论研究和工程实践提供参考。结论表明：全级配与湿筛混凝土试件抗压强度差别不大，全级配混凝土的轴拉强度约为湿筛试件的60％～73％；全级配混凝土的轴拉强度小于劈拉强度。全级配混凝土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大，受影响最大的是极限拉伸性能。全级配及湿筛混凝土试件的28 d抗渗等级都达到W10，但前者更能真实地反映大体积混凝土的抗渗性。

The mechanics, deformation and permeability of full graded concrete with phosphorus slag power were studied， and contrasted with those of wet screened concrete. Results show as follows: Both compressive strengths have a little difference; Tensile strength of the former is 60% to 73% of the later; The compressive elastic modulus of the large specimen is higher than that of the small specimen; The effect of large aggregates on ultimate tensile value is remarkable than on Poisson’s ratio； Both impermeability grades at 28 d all reach W10, but the former can better reflect the true impermeability of large volume concrete.
