双掺技术对田间配套建筑物真空脱水混凝土性能的影响

Effects of Double-mixture Technology on the Performance of Field Matching Structures Vacuum Dehydration Concrete

分析了单掺粉煤灰、减水剂及双掺对田间配套建筑物真空脱水与非真空脱水混凝土强度、抗碳化与氯离子等性能的影响。结果表明,真空脱水技术的应用能明显提高混凝土的性能;单掺粉煤灰或减水剂时,能一定程度提高混凝土的性能;双掺比单掺更能改善混凝土的性能;双掺技术对非真空脱水混凝土性能的影响好于真空脱水混凝土。

Abstract： This paper analysed the effects of uni doped fly ash,water reducing agent and double mixed on the strength,anti-carbonization,chloride ion and other performance of field matching structures non-vacuum dehydration concrete and vacuum dehydration concrete. Results showed that application of vacuum dehydration technology could obviously improve the performance of concrete; uni doped fly ash or water reducing agent could improve the performance of concrete to some extent;double-mixture could improve the performance of concrete better than uni doped;effects of double-mixture technology on the performance of non-vacuum dehydration concrete were better than vacuum dehydration concrete.
