Embodiment Construction

[0039] The following is attached Figure 1-5 The application is described in further detail.

[0040] The embodiment of the present application discloses a concrete preparation process for waste recycling. refer to figure 1 , a concrete preparation process for waste recycling, comprising the following steps:

[0041] Step 1: First, pour the waste concrete into the container for coagulation and hardening;

[0042] Step 2: Take out the hardened waste concrete blocks and transport them to the crusher for crushing. The crushing process can be subdivided into primary crushing and secondary crushing. The hardened concrete is first transported to the jaw crusher for primary crushing. The jaw crusher has a large crushing particle size and can complete the crushing of large pieces of concrete, and then passes through the impact crusher for secondary crushing. Secondary crushing, the impact crusher has small equipment volume, high crushing ratio, and has the function of shaping. The...

Abstract

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.

Description

technical field [0001] The present application relates to the technical field of concrete, in particular to a concrete preparation process for waste recycling. Background technique [0002] Concrete is a general term for composite materials that are composed of gel material, aggregate and water in an appropriate proportion, and then hardened after a certain period of time. It is the most widely used artificial civil construction material in the world. Concrete has high hardness, wide sources of raw materials, and low cost, and is widely used in structures such as houses and roads. Due to the frequent use of concrete by personnel, concrete raw materials are increasingly in short supply. [0003] On the construction site, it often happens that the concrete can no longer be used due to the quality of the concrete, and the personnel generally put the waste concrete on hold or bury it. [0004] With regard to the related technologies mentioned above, the inventor believes that ...
