Admixture for improving appearance of concrete
The invention relates to an admixture capable of improving the appearance of concrete. The admixture is prepared from the following components in percentage by mass: 10.0 to 50.0 percent of a polycarboxylate superplasticizer, 10.0 percent or less of a retarder, 0.05 to 0.3 percent of a defoaming agent, 0.5 percent or less of an air entraining agent, 1 to 10 percent of an alkali preparation and thebalance of water, compared with a common admixture, the admixture disclosed by the invention has the effects of improving the appearance of hardened concrete besides the properties of fresh concretesuch as excellent water reducing rate and compressive strength ratio, and can be applied to various types of concrete with higher appearance requirements.
本发明涉及一种具有改善混凝土外观的外加剂，按照质量百分比计，该外加剂由10.0～50.0％的聚羧酸减水剂、不大于10.0％的缓凝剂质量、0.05～0.3％的消泡剂、不大于0.5％的引气剂、1～10％的碱制剂以及余量的水组成，本发明的外加剂与普通的外加剂相比，在拥有优异的减水率、抗压强度比等新拌混凝土性能外，还具有改善硬化混凝土外观的效果，可用于具有较高外观要求的各类混凝土中。
