Embodiment 1

[0028] The preparation method of the high-performance permeable concrete is as follows:

[0029] Step 1: Classify construction waste, select concrete waste, mud waste and asphalt waste;

[0030] Step 2: Separately select concrete waste, mud waste and asphalt waste, remove dirt and dust on the surface of concrete waste, remove sundries in mud waste, and remove bricks and stones in asphalt waste;

[0031] Step 3: Place concrete waste in a crusher for crushing, and asphalt waste for heating;

[0032] Step 4: Sieve the pulverized concrete blocks, and filter the remaining concrete blocks for secondary crushing and then sieve;

[0033] Step 5: add mud, asphalt, cement, water and rubber powder to the sieved concrete;

[0034] Step 6: Put the mixed mixture into the cement mixer for stirring;

[0035] Step 7: Lay the stirred mixture on the ground, wait for it to be semi-dry, and then lay a layer of asphalt and mud mixture on the surface, and wait for it to dry completely.

[0036] ...

Embodiment 11

[0045] The steps of this embodiment are the same as those of Embodiment 1, except that in step 7, the thickness of the mixture paved is 5 cm, and the thickness of the asphalt paved is 3 cm.

Embodiment 12

[0047] The steps of this embodiment are the same as those of Embodiment 1, except that in step 7, the thickness of the mixture paved is 6 cm, and the thickness of the asphalt paved is 3 cm.

Abstract

The invention discloses a preparation method of high-performance permeable concrete prepared by building rubbish, and belongs to the technical field of buildings. The preparation method includes the steps that 1, the building rubbish is classified, and concrete rubbish, mud rubbish and asphalt rubbish are chosen; 2, the concrete rubbish, the mud rubbish and the asphalt rubbish are respectively selected, dirt and dust on the surface of the concrete rubbish are removed, impurities in the mud rubbish are removed, and bricks and stones in the asphalt rubbish are removed; 3, the concrete rubbish isplaced in a crusher to be crushed, and the asphalt rubbish is heated; and 4, crushed concrete blocks are sifted, and the remaining concrete blocks are filtered for secondary crushing and then siftingis conducted. Through the preparation method, the building rubbish is recovered and reused, only a small amount of unrecycled cement and asphalt are used, meanwhile, permeability performance of asphalt pavement is improved, and sustainable development is facilitated.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a method for preparing high-performance permeable concrete prepared from construction waste. Background technique [0002] With the construction of modern cities, the surface is gradually covered by buildings or concrete, and the coverage of these impermeable materials has brought a great negative impact on the ecological environment of the city. If the groundwater is not replenished, the groundwater level will drop, causing the land to sink; rainwater can only be discharged through the urban drainage network, and when the rainwater is heavy or the urban drainage network fails, it will easily cause waterlogging; coastal areas will also lead to seawater intrusion. On the one hand, urban greening consumes a lot of water for irrigation; on the other hand, a lot of rainwater cannot be used, resulting in a waste of water resources. In this context, pervious concrete and permeabl...
