Improvements of drop-weight testing method and equipment
首发时间:2009-05-28
Abstract:In order to find a better drop-weight testing method and equipment for investigating impact properties of fiber-reinforced concrete, this paper thoroughly analyzed the merits of existed methods (CECS13:2008 and ACI54.4R) , and then improved the drop method, positioning of drop hammer, protecting parts of the equipment, the dimension of specimen and advanced the analytical method to analyze the impact resistance quantitatively. After the adjustment and improvement, according to conducted projects, the equipment and method eliminated the artificial influence which affected the free drop of the drop hammer, prevented the secondary impact on the specimen, protected the safety of the experimenter and made a desired results based on the adapted analytical method.
