钢筋混凝土现浇结构施工中,在保证质量的前提下,缩短拆模时间,加快模板周转速度是加快工程进度、提高经济效益的有效方法。近年来,采用在拌制混凝土时掺入适量早强剂的方法,使混凝土早期强度大大提高,成为缩短拆模时间的主要措施。还能不能找到新的途径呢?混凝土工程施工及验收规范模板工程中明确规定了承重模板拆模时所需要的混凝土强度值。见表 In the construction of reinforced concrete cast-in-place structures, under the premise of ensuring quality, shortening the demoulding time and accelerating the template turnover rate are effective methods for accelerating the progress of the project and improving economic efficiency. In recent years, the use of a suitable amount of early strength agent in the mixing of concrete has greatly increased the early strength of concrete and has become a major measure for shortening the time for demolding. Can not find a new way? Concrete construction and acceptance of the specification template project clearly specifies the concrete strength value required when the load-bearing template is removed.
