| 摘 要： | 研究了高钙粉煤灰不同掺量情况下混凝土的体积安定性及高钙粉煤灰的最大掺量情况下,在不同水胶比、不同掺量情况下混凝土的力学性能及耐久性性能。研究发现：掺高钙粉煤灰混凝土的安定性可通过测定其胶凝材料的安定性来评定,掺加25%左右的高钙灰,所配制的混凝土的强度性能和体积稳定性都较好,随着水胶比的降低,掺高钙粉煤灰混凝土同龄期的抗压强度逐渐增大：掺高钙粉煤灰灰混凝土具有良好的抗渗性能及良好的抗冻性能。

| Abstract: | The volume stability of concrete of different proportion of high calcium fly ash and the different water ratio and different dosage were Study.The results indicated that the stability of high performance concrete which mixed with high calcium fly ash can be assessed by determining the stability of its cementitious material.The intension capability and volume stability of concrete mixed with 25% quantity high calcium fly ash were preferable.The compression strength was increased along with reducing of water cement ratio.The concrete with high calcium fly ash has well impermeability and freezing-thawing resistance. |
