Problems solved by technology

[0004] The concrete permeable bricks produced by the existing technology are low in strength, the surface particles are coarse and the pores may be blocked, and the water permeability is lower; the cost of permeable bricks made of ceramics and polymer materials is relatively high, and it is still in its infancy, and there are few places where it is used In addition, the price is higher than that of ordinary concrete, which also limits the application

preparation example Construction

[0024] The invention relates to a pavement ecological permeable brick and a preparation method thereof, comprising aggregate, powder material and organic binder. Mineral granules and solid wastes are used as aggregates, powdered materials and organic binders in a certain particle size range are added, the ratio of raw materials is optimized and adjusted, after granulation, they are stacked and formed, and fired under certain conditions to prepare Porous permeable bricks, observe and test performance parameters such as firing temperature, porosity and density of permeable bricks.

[0025] see figure 1 ,Specific steps are as follows:

[0026] (1) After the waste glass is ground, it is then sieved and graded to screen out four-grade glass particles of 8 mesh or more, 8-20 mesh, 20-40 mesh and 40-80 mesh; Sieve classification, sieve out more than 8 mesh, 8-20 mesh, 20-40 mesh or 40-80 mesh and mineral particles;

[0027] (2) In terms of mass percentage, weigh 30% to 60% of mine...

Embodiment 1

[0038] (1) Clean and dry the collected waste glass, crush and grind it, then sieve and classify it, and select 20-40 mesh glass particles; first crush and grind the quartz sand, then sieve and classify it, and select 20-40 mesh quartz sand particles;

[0039] (2) Weigh 70g of glass particles of 20-40 meshes and 30g of quartz sand particles of 20-40 meshes, mix and stir evenly to obtain a mixture, put the mixture into a mold, accumulate and form by natural accumulation, and then dry naturally After that, it is placed in a firing furnace and fired at 860°C for 1 hour, and then cooled naturally to room temperature to obtain pavement ecological permeable bricks.

Embodiment 2

[0041] (1) Wash and dry the collected waste glass, crush and grind it, then sieve and classify it, and select 20-40 mesh glass particles; first crush and grind the selected quartz sand, then sieve and classify it, and select 20-40 mesh Quartz sand particles;

[0042] (2) Weigh 60g of glass particles and 40g of quartz sand particles and mix and stir evenly to obtain a mixture, put the mixture into a mold, accumulate and form by natural accumulation, then place it in a firing furnace after natural drying at 860 Burn at ℃ and keep warm for 30 minutes, then cool naturally to room temperature to make pavement ecological permeable bricks.

Abstract

The invention discloses an ecological permeable pavement brick and a preparation method of the brick. The preparation method comprises the steps of sieving waste glass into glass particles with more than 8 meshes, 8-20 meshes, 20-40 meshes and 40-80 meshes, sieving mineral into mineral particles with more than 8 meshes, 8-20 meshes, 20-40 meshes and 40-80 meshes, weighing 30-60% of any-grade mineral particles, 0-20% of glass fine powder and 40-70% of any-grade glass particles according to mass percentage, adding the glass fine powder and a binder aqueous solution to the mineral particles, performing stirring to allow the glass fine powder to be bound on the mineral particles, adding the glass particles, then adding into a grinding tool, and performing stacking and firing. The permeable brick prepared with the method can form a large void ratio by utilizing stacking of the glass particles with the similar particle size, and can form a good, larger-void and stable permeable brick material of a skeleton structure by a cementation effect of glass due to heat preservation at a certain temperature above the softening temperature.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a pavement ecological permeable brick and a preparation method thereof. Background technique [0002] The surface of modern cities is gradually covered by water-blocking materials such as buildings and concrete. This impermeable surface material prevents rainwater from seeping into the ground, resulting in a drop in the groundwater table. In addition, once a storm occurs, it is easy to form a storm only by relying on the drainage of the urban drainage system. Urban flooding. At the same time, the impermeable road surface basically cannot exchange moisture and heat with the air, and cannot adjust the temperature and humidity of the surface, forming an urban "heat island phenomenon" with buildings. On the other hand, with the rapid development of my country's industrialization process, while consuming a large amount of natural resources, it also discharges a lot of soli...
