美国威斯汀豪斯(西屋)公司的科研人员发明了一种检查混凝土质量的新技术,已提出专利申请。这种新技术的要点是:把铁质小颗粒掺到水泥里,利用不同频率的电磁能量来“刺激”这些颗粒,使之产生声波和辐射热;用仪器拾取声波和热力进行分析,能知道水泥是否与沙砾混合均匀。混凝土硬化时,测到的声和热会变化,从中能知道混凝土的固结速度,必要时加以控制。
Researchers at Westinghouse (Westinghouse) in the United States have invented a new technology for checking the quality of concrete and have filed a patent application. The main point of this new technology is to mix small particles of iron into the cement and use the electromagnetic energy of different frequencies to “stimulate” these particles to produce sound waves and radiant heat; using instruments to pick up sound waves and heat to analyze, can know Does the cement mix well with the gravel? When the concrete hardens, the measured sound and heat will change, from which the concrete’s consolidation speed can be known and controlled if necessary.
