建筑钢筋用聚合物防腐砂浆的研究与工程应用
|
摘要
研制了一种新型的建筑钢筋用聚合物防腐砂浆,并在实际工程中进行了应用。通过研究防腐砂浆的力学性能、抗氯离子渗透性能、抗渗性能以及其与钢筋的黏接强度等指标,来探究其在实际工程应用的实用性和可靠性。研究结果表明,该防腐砂浆不仅和易性好,操作简便,而且凝结硬化快,强度增长迅速,28d龄期的抗压强度为92.0MPa;同时其微观结构致密,具有很好的抗渗、抗氯离子渗透性能,且其与钢筋之间黏结能力较强。所研制的聚合物防腐砂浆在实际工程中得到了应用,其施工性能优异,有着较大的应用价值。
A new kind of polymer anticorrosive mortar for reinforced bars is developed, and has been applied in practical engineering. The mechanical properties, anti-chloride ion permeability, impermeability and the bonding strength and other indexes of the polymer anticorrosive mortar is analyzed to explore its practicality and reliability in practical engineering application. The results show that the anticorrosive mortar has good workability and it is easy to operate. Its setting and hardening speed is fast and the growth of its strength is rapid. The compressive strength is 92.0 MPa at 28 d. The microstructure is compact and it has good anti-chloride ion permeability and impermeability. Its bonding with steel is strong. The polymer anticorrosive mortar developed has been applied in practical engineering. Its construction performance is excellent. With a great application value.
