When the compound mineral admixture is mixed,the porosity rate of C20 concrete can be decreased and the less-harm hole is increased, the harmful hole and the more-harmful hole are decreased.
对于C20混凝土,掺入复合矿物外加剂可使混凝土孔隙率降低,少害孔增加,有害及多害孔减少,混凝土早期强度没有降低,后期强度有增大的趋势,对抗渗性、抗腐蚀性较为有利,但对抗冻性改善不明显;掺入引气剂增加了混凝土孔隙率及多害孔,混凝土强度有所降低,对混凝土抗冻性、抗渗性、抗腐蚀性均不利;同时掺这两种物质时,虽增加了混凝土孔隙率,但可以使混凝土的孔径分布相对合理(多害及有害孔减少,无害及少害孔增大),混凝土强度降低不明显,对混凝土抗冻性、抗渗性、抗腐蚀性均有利。
