Crack control method for high-impermeability mass concrete
The invention relates to a construction technology of high-impermeability type concrete, in particular to a crack control method of high-impermeability type mass concrete, which comprises the following steps: optimizing the internal microstructure of the concrete, reducing the internal porosity of the concrete, and weakening the microsiphoning effect of the concrete on water molecules; materials are selected and optimized, so that the generation of hydration heat is reduced; the synergistic regulation effect of multiple admixtures is exerted, and the efficient water reducing agent is used, so that the water consumption is reduced, the water cement ratio is reduced, and the compactness and impermeability of the concrete are improved; a proper amount of expanding agent is added to compensate the shrinkage of the concrete; and quality control in the construction process: manufacturing a 1: 1 entity sample plate section, and performing systematic analysis on the cracking performance of the mass concrete. According to the crack control construction method for the high-impermeability mass concrete, provided by the invention, the crack resistance and impermeability of the concrete are comprehensively improved from the thought of optimizing the internal microstructure of the concrete.
本发明涉及高抗渗型混凝土的施工技术，具体是一种高抗渗型大体积混凝土的裂缝控制方法，包括混凝土内部微观结构优化，降低混凝土内部孔隙率，弱化混凝土对水分子的微观虹吸作用；材料的选择和优化，减少水化热的产生；发挥多外加剂的协同调节作用，使用高效减水剂，减少用水量，降低水灰比，提高混凝土的密实性和抗渗性；添加适量的膨胀剂，补偿混凝土的收缩；施工过程中的质量控制：制作1:1实体样板段，对大体积混凝土开裂性能进行系统性分析。本发明提出的高抗渗型大体积混凝土裂缝控制施工方法，从优化混凝土内部微观结构的思路出发，全面提升混凝土的抗裂和抗渗性能。
