混凝土浇灌后要立即进行充分捣固,使它填满模板各个角落,成为含空隙较少的密实体。混凝土的强度、防水性及耐久性,除受材料及配合比的影响以外,主要取决于混凝土捣固的程度。因此,必须对混凝土的捣固引起足够的重视。 Immediately after the concrete is poured, it must be fully tamped so that it fills all corners of the formwork and becomes a compact body with less voids. The strength, water resistance, and durability of concrete depends on the degree of concrete tamping, in addition to the material and mix ratio. Therefore, sufficient attention must be paid to the tamping of the concrete.
