本文通过碳化对比试验,分析不同种类高效减水剂单独使用及不同种类高效减水剂与缓凝剂复合使用对混凝土抗碳化性能的影响,结果表明单掺脂肪族高效减水剂的混凝土试样抗碳化性能最好,复合使用木钙及糖钙两种缓凝剂能够使试样的抗碳化性能提高,其中高效减水剂与木钙复合使用比与糖钙复合使用更有利于混凝土抗碳化性能的提高。
In this paper, carbonation comparison test, analysis of different types of superplasticizer used alone and different types of superplasticizer and retarder combined use of concrete anti-carbonation performance results show that single admixture superplasticizer concrete samples The best anti-carbonation performance, the complex use of wood calcium and calcium and calcium two retarders can make the anti-carbonation performance of the sample, in which superplasticizer and wood calcium composite than the use of calcium and calcium compound is more conducive to the anti-carbonation Performance improvement.
