Mass concrete temperature control and shrinkage compensation method
The invention discloses a mass concrete temperature control and shrinkage compensation method, and belongs to the technical field of temperature control and crack control in concrete construction, and the method specifically comprises the following steps: preparing cold storage units, and uniformly adding the cold storage units into a concrete base material according to the volume of the concrete base material; and organic microcapsules with thermal expansion and cold contraction characteristics are contained in the cold storage units. The phase change characteristic of the quick-freezing concrete cold storage unit is ingeniously utilized for temperature control, the deformation characteristic of thermal expansion and cold contraction of a capsule material is utilized for shrinkage compensation, the size and the shape of the cold storage unit can be designed according to a reinforcement cage, a brand new technical scheme is provided for temperature control and crack control of mass concrete, and the method is suitable for mass concrete production. The problems that an existing method is complex in equipment arrangement structure, high in operation cost, difficult in wastewater treatment, complex in operation and the like can be effectively solved.
本发明公开了一种大体积混凝土温度控制和补偿收缩方法，属于混凝土施工中温度控制和裂缝控制技术领域，具体方法为：制备蓄冷单元，然后根据混凝土基材的体积向其中均匀添加蓄冷单元即可；蓄冷单元内部含具有热胀冷缩特性的有机微胶囊。本发明巧妙利用急速冷冻混凝土蓄冷单元的相变特性进行控温，利用胶囊材料热胀冷缩的变形特性进行收缩补偿，蓄冷单元尺寸及形状可依据钢筋笼进行设计，为大体积混凝土温度控制和裂缝控制提供了全新技术方案，可有效解决现有的方法存在的设备布置结构复杂、运行费用高、废水处理难以及操作复杂等问题。
