According to the results of particl

According to the results of particle classification experiment, the particle size of coarse aggregate is large, especially the oversized material (> 120mm) is large, and each storage yard is different, with an average of 11%; the fine aggregate is small, containing < 0.15mm fine sand, but the total reserves of fine aggregate are rich. It is estimated that 6.05 million cubic meters of coarse aggregate and 3.08 million cubic meters of fine aggregate can meet the demand of the project. There is a lack of local soil, only a small amount of loam, most of the interlayer is about 0.5m thick, without certain regularity, distribution is not centralized, and it is not easy to mine.
