Abstract

The invention discloses a recycled aggregate ecological water permeable brick and a production method thereof. The raw material of the recycled aggregate ecological water permeable brick comprises a basic material, a surface material and water, the basic material comprises recycled aggregate, a gel material and additives, the gel material comprises cement, lime and coal ash, and the additives comprise a polycarboxylate superplasticizer and gelatine powder. The production method of the recycled aggregate ecological water permeable brick comprises the following steps: grading, extracting and preparing for discharging of the recycled aggregate, stirring the basic material, stirring the surface material, forming, curing and forming the finished product. The recycled aggregate ecological water permeable brick disclosed by the invention is produced by building wastes after resourceful treatment, which both promotes the resource utilization of the building wastes to improve the added value of products, and saves a large number of natural sand and stone resources; the produced recycled aggregate ecological water permeable brick has a high permeable rate, a high water-retention rate and high compressive strength, and the compressive strength reaches 30 MPa; and the permeation coefficient is 0.5 cm/s, which is 50 times as large as that of the existing national standard and much better than the properties of similar natural material products.

Description

technical field [0001] The invention relates to the field of building material concrete, in particular to a recycled aggregate ecological permeable brick and a production method thereof. Background technique [0002] With the development of urbanization, more and more hard ground is laid in the city, which has poor environmental protection function and is not suitable for human habitation. For example, the heat island effect of the concrete floor, ground water and urban waterlogging caused by poor drainage, and the inability of natural precipitation to infiltrate and replenish groundwater lead to the destruction of the groundwater cycle. Existing concrete pavement bricks are a typical hard ground, mostly solid bricks, with a very low water permeability coefficient and basically no water permeability function. Contents of the invention [0003] The object of the present invention is to provide a recycled aggregate ecological permeable brick with high compressive strength a...
