机制砂亚甲蓝试验标准

机制砂的亚甲蓝(MB)值解读 百家号

对于机制砂亚甲蓝(MB)值的正确表述应当为用于确定机制砂中粒径小75μm的颗粒是否存在膨胀性黏土矿物并确定其含量的整体指标。 图1 泥粉含量与MB值 1、亚甲蓝法是目前机制砂石粉含量检测的主要方法,国内石粉含量亚甲蓝试验方法主要是参照欧洲标准ew9339:1999《骨料几何特性试验中的细粉评估—亚甲蓝试验》; 2、亚甲 机制砂石粉含量亚甲蓝试验方法 百度文库

《建设用砂》新国家标准将于11月1日起施行,

新——亚甲蓝(MB)值定义: 用于判定机制砂吸附性能的指标。 4 混合砂定义: 由机制砂和天然砂按一定比例混合而成的砂。 5 机制砂片状颗粒定义: 粒 本规范的主要技术内容: 1 总则; 2 术语; 3 基本规定; 4 机制 砂技术要求与验收规则; 5 机制砂砂浆、机制砂混凝土技术要求; 6 机制砂砂浆、机制砂混凝土配合比设计; 7 机制砂砂 机制砂应用技术规范 深圳市住房和建设局
