和易性测试仪是目前我国建筑业混凝土性能测试的新型仪器。它不仅可以测试混凝土流动度数值,而且可以测试混凝土和易性数值。是从事混凝土施工和生产单位,督测和控制混凝土质量的有效手段。我们参考国外先进技术,结合本地情况进行研究试验,并对北京市十来家混凝土生产和施工单位进行了200多次实地测试和对比试验,收到了良好的效果。一、和易性测试仪原理 1.混凝土流动度测试原理:流动度测试是
The workability tester is a new type of instrument for testing the performance of concrete in China’s construction industry. It can not only test the value of concrete fluidity, but also test the workability of concrete. Is engaged in concrete construction and production units, supervision and control of concrete quality and effective means. We refer to foreign advanced technology, combined with local conditions for research and testing, and Beijing dozens of concrete production and construction units conducted more than 200 field tests and comparative tests, received good results. First, the workability tester principle 1. Concrete fluidity test principle: fluidity test is
