为使高强混凝土达到超早强,提高生产率和模板的周转率,以C80混凝土为例,使用高强混凝土配合比设计,在不添加任何掺合料的情况下,仅添加高效减水剂,在封闭保湿加热的条件下进行养护,实现了C80高强混凝土的超早强,即养护12h强度达到设计强度的80%以上,为超早强混凝土的生产提供了参考和依据。 In order to achieve ultra-early strength of high-strength concrete and increase productivity and turnover rate of the formwork, C80 concrete is taken as an example. Using high-strength concrete mix design, without adding any admixture, only superplasticizer is added, Moisturizing heating conditions for the conservation, to achieve ultra-early strength of C80 high-strength concrete, that is, conservation 12h strength of more than 80% of the design strength, for the ultra-early strength concrete production provides a reference and basis.
