骨料是耐酸混凝土的主要骨架，直接影响耐酸混凝土的理化性能和技术指标。除粗细度外，其余与粉料相同，骨料常用的是石英石(砂)，有耐高温要求的选用耐火粘土砖碎块，粗细骨料要有良好的级配。
Aggregate is the main framework of acid-resistant concrete, which directly affects the physical and chemical properties and technical indicators of acid-resistant concrete. Except for the fineness, the others are the same as the powder. Quartz stone (sand) is commonly used as aggregate. Fire-resistant clay brick fragments are selected for high temperature resistance, and fine aggregate should have good gradation.
