自密实混凝土密实度及表观质量试验研究

Study on Compactness and Apparent Quality Control for the Self-compacting Concrete

  • 摘要: 通过对比试验的方法,研究了在混凝土中添加消泡剂和在其表面贴透水模板布对混凝土的密实度和表观质量的影响。通过测试和分析发现:添加消泡剂后自密实混凝土的密实度、表观质量及强度都得到了提高,而且在使用透水模板布后构件的表观质量能得到进一步提高;因此,采用既添加消泡剂又贴透水模板布的方法能使混凝土构件的密实度及表观质量得到双重提高,有利于提高混凝土的耐久性。

     

    Abstract: The effects of foam resistance agent and infiltrating formwork texture on compactness and apparent quality of concrete have been investigated by contrast test method. The results show that the compactness, apparent quality and strength of self-compacting concrete are improved by adding foam resistance agent. Moreover, the apparent quality can be further improved by using infiltrating formwork texture. Hence,it is a good way to enhance the compactness and apparent quality of concrete by adding foam resistance agent and using infiltrating formwork texture, meanwhile, it is benefit to improve the durability of concrete.
