本文按照富勒级配理论进行粗骨料搭配组合,可以获得最大的堆积密度和最小孔隙率。以富勒级配颗粒组成为标准,用骨料的筛析结果,可以计算出向富勒级配靠近的搭配比例。要实现骨料最佳的搭配组合,各骨料自身合理的颗粒分布是关键;用三级复配的方式可明显改善混合骨料的堆积状态;应依据富勒级配要求制定骨料级配标准,对供应商提出要求。 In this paper, according to Fuller grading theory with coarse aggregate collocation combination, you can get the maximum bulk density and minimum porosity. To Fuller graded particle composition as a standard, with the aggregate sieve results, you can calculate the proportion of close to the Fuller gradation. To achieve the best combination of aggregates, the rational distribution of the particles is the key to their own; with three-way compound can significantly improve the accumulation of mixed aggregate state; should be based on Fulle grading requirements to develop aggregate gradation Standard, the supplier requirements.
