【摘要】 造成混凝土孔隙有内部与外部原因。孔隙与混凝土的质量、材料属性密切相关。减少孔隙的途径就是提高混凝土质量,改善各种材料性质的科学方法。文中较详细论述混凝土孔隙的各种降低方法的依据;孔隙对材料的强度,弹性模量、变形与耐久性的影响论述尤为详尽。更多还原

【Abstract】 The reason for concrete pores involves the internal and external ones.The concrete pores take a closed relation with the quality of concrete and the material property.The way to reduce the existence of concrete pores is to improve the quality of concrete and to improve the properties of various materials.various methods to reduce the existence of concrete pores are introduced in detail,especially on the effect of concrete pores upon the materials strength,elastic modulus,deformation as well as the aging resistance.更多还原
