摘要:
一般商品混凝土的水泥用量比较大,产生的水化热较多,在大体积浇筑或冬季施工中,容易造成混凝土内外温差过大,从而引起裂缝,因此在设计中,应对结构中的节点、应力集中处和大体积混凝土沿截面均匀布置细而密的构造钢筋,以提高结构物的抗裂能力.并通过采取在商品混凝土中添加各类外加剂,适当减少水泥用量及延长养护时间、降低构件内外温差等措施,降低混凝土结构产生裂缝的可能性.
Abstract:
Generally, the amount of cement used in commercial concrete is relatively large, and the hydration heat generated is more, and in large-volume pouring or winter construction, it is easy to cause excessive temperature difference between the inside and outside of concrete, thereby causing cracks, so in the design, the joints, stress concentrations and large volume of concrete in the structure should be evenly arranged along the section of fine and dense structural steel bars to improve the crack resistance of the structure. By adding various admixtures to commercial concrete, appropriately reducing the amount of cement, extending the curing time, and reducing the temperature difference between the inside and outside of the component, the possibility of cracks in the concrete structure is reduced.
