Ecological high-quality utilization method of concrete solid waste
The invention belongs to the technical field of construction waste treatment, and particularly relates to a concrete solid waste ecological high-quality utilization method which comprises the following steps: step 1, crushing: crushing a waste concrete pattern, and separating aggregate and cement components; step 2, screening: screening the aggregate according to the particle size of 100mm through a linear vibration feeder after primary crushing, so as to obtain the aggregate with the particle size of more than 100mm and the aggregate with the particle size of less than 100mm; step 3, secondary crushing: crushing the aggregate with the particle size of more than 100mm again; classifying finished products obtained by crushing in the step 1 and the step 3 according to particle sizes; 5, the cement components separated in the step 1 are processed through a low-temperature calcination technology, the regenerated cementing material with hydration activity can be prepared, the structure is reasonable, in the using process, the treatment mode of waste concrete is widened, the recycling rate of the waste concrete is increased, resource waste can be prevented, and meanwhile secondary pollution can also be prevented.
本发明属于建筑垃圾处理技术领域,具体为一种混凝土固废生态高质化利用方法,包括步骤1:破碎,对废弃混凝图进行破碎,分离骨料和水泥组分;步骤2:分筛,经初破后的建筑废弃混凝土通过直线振动给料机,将骨料的粒径按照100mm进行筛分,得到粒径大于100mm的骨料及粒径小于100mm的骨料:步骤3:二次破碎,将粒径大于100mm的骨料进行再次破碎:步骤4:二次粉筛,将步骤1和步骤三破碎得到的成品按照粒径进行分类;步骤5:利用低温煅烧工艺,对步骤1中分离出的水泥组分进行加工,可制备得到具有水化活性的再生胶凝材料,其结构合理,在使用的过程中,拓宽废弃混凝土的处理方式,提高其回收利用率,可以防止资源浪费的同时,也可以防止二次污染。
