Concrete production technology with waste recycled
The invention relates to a concrete production technology with waste recycled. The concrete production technology with the waste recycled comprises the following step: setting and hardening waste concrete, conducting secondary crushing after waste concrete blocks are subjected to primary crushing, screening crushed concrete granules, transporting the concrete granules to a reinforcing device for reinforcing, conducting over-drying after the concrete granules are reinforced, and supplying the over-dried concrete granules to fresh concrete for use as gravels and aggregates with the strength level lowered by two levels according to the original strength level of the waste concrete, wherein the reinforcing device comprises an immersion tank, a turning conveyor belt and turning devices, and anultrasonic oscillator is arranged on a bottom wall of the immersion tank. By means of the production technology, the waste concrete can be processed so that the waste concrete can serve as the fillingaggregates of the fresh concrete for reuse, and thus the production technology is environmentally friendly and economical; and by arranging the ultrasonic oscillator, the infiltration speed of a sodium silicate solution into the concrete granules can be improved, so that the processing efficiency is improved.
本申请涉及一种废弃物再生利用的混凝土制备工艺，包括以下步骤：废弃混凝凝结硬化，对废弃混凝土块进行一次破碎之后再进行二次破碎，对破碎后的混凝土颗粒进行筛选，对混凝土颗粒输送到强化装置进行强化，强化装置包括浸入池、变向传输带、变向装置，浸入池底壁设有超声波震荡器，混凝土颗粒强化之后过干燥，按照废弃混凝土的原强度等级降低2个等级供应给新拌混凝土以当作砂砾与碎石使用。本制备工艺可对废弃混凝土进行加工，使其能够充当新办混凝土的填充碎石进行再利用，较为环保节约；通过设置超声波震荡器，可加快硅酸钠溶液对混凝土颗粒的渗入速度，提高加工效率。
