Mix proportion design method for high-durability self-compacting concrete containing metakaolin
The invention relates to a method for designing the mix proportion of high-durability self-compacting concrete containing metakaolin. The method comprises the following steps: determining the compressive strength and slump expansion degree value of the self-compacting concrete according to engineering requirements; determining the total amount of a powder cementing material required for preparing the self-compacting concrete; determining the ratio of cement replaced by metakaolin, the cement consumption and the metakaolin consumption; determining the water consumption required by the self-compacting concrete; determining the dosage of a water reducing agent; determining the amount of coarse aggregate and the amount of fine aggregate; and calculating the dosage of each component of the self-compacting concrete and preparing the self-compacting concrete for testing. By introducing the efficiency coefficient of the metakaolin, the invention provides the design method for the mix proportion of the self-compacting concrete containing the metakaolin, and the problem that engineering technicians are difficult to design the self-compacting concrete containing the metakaolin according to engineering requirements is solved.
本发明是一种含偏高岭土的高耐久自密实混凝土配合比设计方法，包括以下步骤：根据工程需求确定自密实混凝土的抗压强度和坍落扩展度值；确定配制自密实混凝土所需的粉体胶凝材料总量；确定偏高岭土替换水泥的比率、水泥用量和偏高岭土用量；确定自密实混凝土所需的用水量；确定减水剂剂量；确定粗骨料用量和细骨料用量；计算自密实混凝土的各组分用量并配置自密实混凝土进行测试。本发明通过引入偏高岭土的效率系数，提出了含有偏高岭土的自密实混凝土配合比设计方法，解决了工程技术人员难以根据工程需求设计出含偏高岭土的自密实混凝土的难题。
