Method for preparing recycled concrete by using waste concrete
The invention belongs to the technical field of recycled concrete, and discloses a method for preparing recycled concrete from waste concrete. The method for preparing the recycled concrete from the waste concrete comprises the following treatment steps of S1, pretreatment, S2, sorting, S3, crushing, S4, screening, S5, secondary grading and S6, regeneration. The method has the advantages that the recycled concrete with high compressive strength and slightly reduced elastic modulus is successfully prepared by using the waste concrete blocks, compared with common concrete, the recycled concrete has the effects of low cost, pollution reduction and waste reduction, the concrete recovery rate is greatly increased, secondary pollution is avoided, and the recycled concrete is suitable for popularization and application.
本发明属于再生混凝土技术领域，公开了一种使用废弃混凝土制备再生混凝土的方法。本使用废弃混凝土制备再生混凝土的方法，包括以下处理步骤：S1.预处理、S2.分选、S3.破碎、S4.筛分、S5.二次分级和S6.再生。本发明有以下优点：使用废弃混凝土块，成功制备出了抗压强度高、弹性模量仅略减少的再生混凝土，相对于普通混凝土，有着成本低廉，减少污染，降低浪费的效果，大幅度提高了混凝土回收率，没有二次污染，适宜于推广使用。
