摘要
通过大量的试验数据分析粗集料的级配、压碎值及含泥量等技术指标对混凝土的性能影响,并对桥梁施工中水泥混凝土用粗集料的质量控制提出了建议,以提高混凝土性能,达到预期目标。
According to the large number of the experimental data,the paper analyzes the influence of the technical indexes,including the gradation of the aggregate,the crushing value,the mud content,on the concrete performance,and points out the suggestions for the quality control of the aggregation of the cement concrete in bridge construction,so as to improve the concrete performance and to achieve the expected aims.
