预应力钢筒混凝土管砂浆保护层在水污染环境下的腐蚀与防护措施

【摘要】预应力钢筒混凝土管水泥砂浆保护层对管体起到防腐与保护作用，但在水污染环境日益严峻的形势下，仅仅依靠制作致密水泥砂浆保护层的防腐措施是不完善的，还应从改善水泥砂浆原材料组成着手，提高水泥砂浆自身的抗腐蚀性能和抗渗透能力，才能有效阻止有害物质的侵入。

Abstract: The cement-mortar coating of prestressed concrete cylinder pipe(PCCP) is adopted to the anti-corrosion and protection of PCCP. But in the increasingly serious condition of water pollution, it is imperfect to rely solely on the cement-mortar coating to prevent corrosion. Improving the composition of its raw materials of cement-mortar to raise the anti-corrosion and anti-infiltration ability can effectively prevent the encroachment of harmful substances

Key words: PCCP; coating; anti-corrosion
