摘要
高耐久补偿收缩混凝土的特征是具有优异的耐久性能。通过优选原材料并掺加镁质膨胀剂,配制出了符合要求的高耐久补偿收缩预拌混凝土,其不仅拌合物工作性能优良,抗开裂、抗氯离子渗透、抗碳化及抗硫酸盐侵蚀等耐久性能也明显优于普通混凝土。该混凝土已成功应用于成都天府国际机场工程建设中,性能优良。
High durability shrinkage compensating concrete has excellent durability.By optimizing raw materials and adding magnesia expansive agent,we have prepared high durability shrinkage compensating ready-mixed concrete,which not only has excellent performance,but also has better durability,such as cracking resistance,chloride ion penetration resistance,carbonization resistance and sulfate corrosion resistance.The concrete has been successfully applied in the construction of Chengdu Tianfu International Airport with excellent performance.
