摘要: 研发了适用于西北盐渍地区特殊地质水文环境下输电塔的耐腐蚀桩基础混凝土配方。该配方除了添加高性能减水剂外,还双掺了50%的粉煤灰和炉渣粉。对混凝土的抗硫酸盐腐蚀、抗硫酸盐-氯盐复合腐蚀、抗氯离子渗透和抗冻融性能进行了试验,并对该耐腐蚀性混凝土的使用寿命进行了预测。试验结果和寿命预测均表明,采用了该配方混凝土的输电线路桩基础具有很好的耐久性,并能满足预期的设计寿命要求,适于同类工程借鉴。

Abstract: A corrosion-resistant concrete formula for transmission line pile foundation, which is applicable in western saline soil area, is proposed. Besides adding high-performance water-reducing agent, 50% fly ash and cinder powder are added in the concrete. The tests, including sulfate solution attack test, sulfate-chloride compound attack test, chloride ion permeability test and freeze-thaw test etc were carried out. The service life of the concrete is predicted based on the method presented by Jin. Based on the results, it can be concluded that the pile foundation can perform excellent durability and the requirements of the expected designed-life are satisfied by applying the formula proposed.

Key words: saline soil area, corrosion-resistant, transmission line, pile foundation, concrete formula, life prediction
