Rubble concrete is commonly used in much of the foundation works. Such as rubble concrete strip foundations, rubble concrete pads, and the like. The method is also used for pouring large-volume concrete, and a certain amount of rubble is added into the poured concrete in order to reduce the damage of the heating value to the structure by reducing the using amount of the cement. When the cast concrete wall is thicker, a certain amount of rubble is also mixed, such as a rubble concrete retaining wall and the like. In the construction of the rubble concrete, the volume of the mixed rubble is generally about 25 percent, and the particle size of the rubble is controlled to be below 200; the concrete operation is that firstly the slurry is discharged and then the rubble is added, so that the slurry is fully wrapped, and the uniform arrangement of the rubble in the space of the structure body is ensured. Wherein, the rubble should be selected from solid, undegraded, crack-free and clean stone materials with the strength grade not lower than MU 20; the size of the rubble should not be larger than 1/3 of the minimum width of the poured part, and the particle size should not be larger than 30 cm; if the surface has sludge and water rust, the surface is washed clean by water.
