【砂石孔隙率和空隙率，如何辨别控制密实度？】知乎

Web说的空隙率，不能把它脱离整个配比环境单独说。通常在配合比中的砂石比，以一定浆骨比（或骨料总量）下的砂率表示。对级配良好的石子，砂率的选择以石子松堆空隙率与砂的松堆空隙率乘积为 016~02 为宜。Web骨料石子空隙率越大，混凝土的浆体量相对较高，混凝土的经济性也就越差。混凝土浆体数量的增加会带来较大的收缩，产生较多的细微裂缝，对混凝土的耐久性造成不利的影响。【骨料粒度、最小空隙率怎么控制】知乎知乎专栏Web15 Mar 2023 P 材料孔隙率（%）; V0 材料在自然状态下的体积，或称表观体积，cm或m;ρ0为材料体积密度，g /cm或kg/ m; V 材料的绝对密实体积，cm或m; ρ为材料密材料的孔隙率计算方法知乎知乎专栏Web通过表观密度、堆积密度的测定，计算出材料的孔隙率及空隙率，从而了解材料的构造特征，便于掌握材料的特性和使用功能。二、实验仪器 1、砂的表观密度（容量瓶法）：容实验三：砂、石表观密度，砂松堆密度，砂、石空隙率实验
