水工混凝土配合比的选择方法虽多,但总的说来,目前还是离不开试验室的常规试验,随着群众性中小型水利工程的大量兴建,对水工混凝土使用日益广泛,迫切要求提供一种能在工地现场进行的简捷试验方法。我们遵照毛主席“要认真总结经验”的教导,深入现场,调查研究,在有关单位大力协助下,从总结施工经验和试验成果入手。采取坍落筒、回弹 Although there are many ways to choose hydraulic concrete mix, on the whole, the general test of laboratory is still impossible. With the massive construction of mass small and medium-sized hydraulic projects, the hydraulic concrete is more and more widely used, Provide a simple test method that can be performed at the jobsite. Following the guidance of Chairman Mao’s “serious lessons learned”, we conducted in-depth investigations on site and conducted investigations. With the help of the relevant units, we started with a summary of construction experience and test results. Take a slump tube and rebound
