Preparation method of impermeable recycled concrete
The invention discloses a preparation method of impermeable recycled concrete, and relates to the field of concrete production, and the preparation method comprises the following steps: 1, feeding waste concrete blocks into a crusher, crushing into waste concrete particles, sequentially feeding the particles into screening equipment and magnetic separation equipment, and preparing the waste concrete particles into concrete particles; crushed waste concrete particles are screened through the ultrasonic vibrating screen, and too large and too small particles are discharged, so that uneven stirring and reduction of concrete strength during subsequent concrete preparation are avoided; meanwhile, reinforcing steel bar particles in the concrete particles are separated from the concrete particles containing the reinforcing steel bar particles through the dry magnetic separator, so that the reinforcing steel bars are prevented from influencing subsequent mixing, and liquid is prevented from penetrating through gaps between the reinforcing steel bars and the concrete particles to permeate; the density, the structural strength and the impermeability of the concrete are effectively improved, so that the subsequent service life of the concrete is prolonged.
本发明公开了一种抗渗再生混凝土的制备方法，涉及混凝土生产领域，包括如下步骤，步骤一，将废弃混凝土块送入破碎机内破碎成废弃混凝土颗粒，之后将颗粒依次送入筛选设备和磁选设备内将废弃混凝土颗粒制成混凝土颗粒。本发明通过超声波震动筛将破碎后的废弃混凝土颗粒进行筛选将颗粒过大和过小的颗粒排出避免后续制备混凝土时搅拌不均匀和混凝土强度降低，同时通过干式磁选机将混凝土颗粒中的钢筋颗粒和包含有钢筋颗粒的混凝土颗粒分离，以避免钢筋影响后续混合以及液体会穿过钢筋与混凝土颗粒之间的缝隙渗入，有效增加混凝土的致密度、结构强度和抗渗性从而延长混凝土后续的使用寿命。
