英国水泥混凝土协会的开发公司应英国建筑界的要求研制成功预拌混凝土中水泥含量高速分析试验机(图1)。它只需要5分钟就能自动测出预拌混凝土中的水泥含量。采用这种装置进行混凝土的质量管理和检查,能使各种作业大大合理化。 The British cement concrete association development company developed a high-speed analysis and testing machine for cement content in ready-mixed concrete according to the requirements of the British construction industry (Figure 1). It only takes 5 minutes to automatically measure the cement content in ready-mixed concrete. The use of this device for quality control and inspection of concrete can greatly rationalize various operations.
