Problems solved by technology
[0004] The invention provides a method for preparing recycled concrete mixed with waste concrete blocks, and aims to solve the following problems in the current process of preparing recycled concrete: (1) The size of the concrete granules obtained after crushing waste concrete blocks is not large; Part of the granules are not fully crushed, which affects the performance of recycled concrete; (2) When the waste concrete blocks are broken, the generated concrete granules are easily adsorbed on the crushing mechanism under pressure, which affects the performance of the crushing mechanism. The use effect will cause adverse effects, which will also affect the performance of recycled concrete

Embodiment Construction
[0036] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.
[0037] like figure 1 As shown, the present embodiment provides a method for preparing recycled concrete doped with waste concrete blocks, comprising the following steps:
[0038] Step 1, raw material treatment: crushing and cleaning waste concrete blocks to obtain recycled aggregates.
[0039] Step 2, mixing and stirring: adding cement to the regenerated aggregate prepared in step 1, and stirring evenly to obtain a mixed dry material.
[0040] Step 3, adding water and stirring: adding water to the mixed dry material prepared in step 2, and stirring to obtain recycled concrete.
[0041] Wherein, in the step 1, the process of crushing the discarded concrete blocks adopts such as Figure 2 to Figure 7 The shown apparatus for preparing recycled concre...

The invention belongs to the technical field of concrete, and in particular relates to a method for preparing recycled concrete doped with waste concrete blocks, comprising the following steps: step 1, raw material processing: crushing and cleaning the waste concrete blocks to obtain recycled aggregates; step 2, Mixing and stirring: adding cement to the regenerated aggregate prepared in step 1, and stirring evenly to obtain mixed dry material; step 3, adding water and stirring: adding water to the mixed dry material prepared in step 2, and stirring to obtain regenerated concrete; wherein, step 1 The process of crushing the discarded concrete blocks is completed by a recycled concrete preparation device. The invention ensures that the waste concrete blocks can be fully broken, avoids the particles being adsorbed on the surfaces of the first bead and the second bead, and ensures the use performance of the recycled concrete.
Description
technical field [0001] The invention belongs to the technical field of concrete, in particular to a method for preparing recycled concrete mixed with waste concrete blocks. Background technique [0002] Recycled concrete refers to new concrete made by crushing and cleaning waste concrete blocks, replacing part or all of natural aggregates such as sand and gravel, and then adding cement and water. According to the combination of aggregates, recycled concrete can be in the following situations: the aggregates are all recycled aggregates; the coarse aggregates are recycled aggregates, and the fine aggregates are natural sand; The material is recycled aggregate. At present, there are the following problems in the process of recycled concrete preparation: (1) the size of concrete fragments obtained after crushing the waste concrete blocks is uneven, and some fragments cannot be fully broken, which affects the performance of recycled concrete; ( 2) When the waste concrete blocks...
