摘要
在现行规范网篮法测试粗骨料密度方法的基础上,进行了粗骨料浸水24h前后的受力状态分析,以骨料浸水24h前后的水中质量差计算骨料的吸水量,由此计算骨料的表干质量。新试验方法在研究过程中,进行了试验的过程设计并进行了大量试验验证,并且与现有试验方法进行了测试数据的对比分析,发现该方法科学合理,测试的数据准确稳定。
On the basis of the code method, the stress states of coarse aggregate are analyzed before and after 24h. The aggregate water absorption is calculated by the quality different which experiences before and after soaking of 24h, and the aggregate dry quality is obtained. In the research process of the new test method,the test process design and a lot of verification are done. Through the comparison analysis of the new method and the code method, it is concluded that the new method is scientific, reasonable and the test data is accurate and stable.
