（1）水泥进场时，必须有质量证明书，并应对其品种、标号、包装（散装仓号）、出厂日期等进行检查验收。用于承重结构的、对水泥质量有怀疑或水泥出厂超过三个月（快硬硅酸盐水泥为一个月）时，应复查试验，并按其试验结果使用。0s7™É²Â–ãbbs.3c3t.comÅJKK˜
复试项目：抗压强度、抗折强度和安定性，必要时加试凝结时间等（根据需要可采用水泥快速检验方法预测28天强度）。0s7™É²Â–ãbbs.3c3t.comÅJKK˜
（2）凡水泥强度低于水泥标号规定的指标，或水泥的四项指标（细度、凝结时间、烧失量和混合材料掺加量）中任一项不符合国家标准规定时，称为不合格产品。0s7™É²Â–ãbbs.3c3t.comÅJKK˜
（3）水泥厂应在水泥发出日起十一天内，寄发水泥品质试验报告。试验报告中应包括除28天强度以外的各项试验结查，28天强度数值应在水泥发出日期起32天内补报。0s7™É²Â–ãbbs.3c3t.comÅJKK˜

3、混凝土外加剂0s7™É²Â–ãbbs.3c3t.comÅJKK˜
（1）必须有生产厂家出示的符合国家标准的质量证明书。内容包括：厂名、品种、质量、重量、包装、出厂日期、性能和使用说明。使用前应进行性能试验。需要时应检验氯化物、硫酸盐等有害物质的含量，经验证确认对混凝土无有害影响方可使用。0s7™É²Â–ãbbs.3c3t.comÅJKK˜
（2）按北京市建委在本市建设工程中使用认证产品监督管理工作规定，凡向本市建设工程销售外加剂的，均须持有北京市建材行管办统一印制的“北京市外加剂使用认证产品销售证”。0s7™É²Â–ãbbs.3c3t.comÅJKK˜
（3）根据北京市建委有关规定，外加剂应作含碱量试验，并且应由生产企业提供碱含量和使用说明带入每1立方米混凝土的碱量应在1kg以下。0s7™É²Â–ãbbs.3c3t.comÅJKK˜
（4）督促和检查承包单位对不同品种外加剂分别存储，做好标记，防止混杂、错用。0s7™É²Â–ãbbs.3c3t.comÅJKK˜
4、混凝土掺合料0s7™É²Â–ãbbs.3c3t.comÅJKK˜
（1）为改善混凝土某些性能或节约水泥，在采用硅酸盐水泥或普通硅酸盐水泥拌制混凝土时可掺入水硬性或填充性掺合料。其质量应符合相对应的标准规定（粉煤灰在混凝土和砂浆中应用技术规程JGJ28—86等）。但掺量应经系统试验验证，确认混凝土质量符合要求，用以确定最大取代水泥量。0s7™É²Â–ãbbs.3c3t.comÅJKK˜
（2）掺合料易与水泥混淆，常因管理不善，在运输与存储时两者混淆误用，造成混凝土质量事故。因此，要设计明显标志，严防混淆误用。0s7™É²Â–ãbbs.3c3t.comÅJKK˜
5、混凝土用水应符合国家现行〈混凝土拌合用水标准〉的规定。0s7™É²Â–ãbbs.3c3t.comÅJKK˜
