四、混凝土配合比. 混凝土配合比是指混凝土中各组成材料（水泥、水、砂、石）之间的比例关系。. 有两种表示方法：一种是以1立方米混凝土中各种材料用量，如水泥300千克， （2）砂率在考虑机制砂细度模数的同时，其所含石粉会是实际砂率降低，所以机制砂的砂率应比天然砂率高，根据实际试拌结果应高出2%-4%左右。 在保证混凝土和易性良好的前 机制砂混凝土配置3个注意事项，原材料、配合比参数

一、混凝土配合比表示方法 1．单位用量表示法：以每1m3混凝上中各种材料的用量表示（例如水泥：水：细集料：粗集料＝330kg:150kg:706kg:1356kg)。 2．相对用量表示法，以 混凝土的砂率指混凝土中砂的用量占砂、石总用量的百分率，砂率是混凝土配合比的重要参数，其大小直接影响混凝土的和易性、强度、体积稳定性等性能。砂在混凝土中的作用起 【砂率的确定方法】

砂率是混凝土中“砂”的质量与“砂和石”总质量之比。一般用βs表示，βs=砂/（砂+石），在混凝土配合比计算中常用。在建筑材料中，粒径5mm以下称为砂，5mm级以上称为碎石。砂 Products.
