Problems solved by technology

[0004] However, most of the current permeable bricks use quartz sand, granite, etc. as the main raw materials, and the resource consumption is high.
In the prior art, it is proposed to use industrial solid waste to produce permeable bricks, but using industrial solid waste as raw material, it is difficult to balance the performance of permeable bricks, and it is difficult to meet the performance requirements of permeable bricks, making the formula design very difficult

preparation example Construction

[0063] The present invention also provides a method for preparing the permeable brick described in the above technical solution, comprising the following steps:

[0064] a) mixing waste ore, cement, silica fume, additives and water to obtain surface layer slurry;

[0065] b) mixing waste ore, cement, iron tailings and water to obtain bottom layer slurry;

[0066] c) After distributing the bottom slurry, carry out initial pressure;

[0067] d) distributing the surface layer slurry on the bottom layer slurry after the initial pressure, and performing vibratory hydraulic pressure to obtain a permeable brick;

[0068] The steps a) and b) are not limited in sequence.

[0069] Wherein, the types and dosages of the waste ore, cement, silica fume, additives, iron tailings and water are consistent with those described in the above technical solution, and will not be repeated here.

[0070] Regarding step a): the mixing process is preferably as follows: firstly, the waste ore is stir...

Embodiment 1

[0081] S1. Add 80% of iron ore waste rock aggregate (5-10mm) and 20% of cement a into a forced mixer, and dry mix for 1 minute; then add water and stir (the water-cement ratio is 0.28) for 8 minutes to obtain the bottom layer slurry material.

[0082] S2. Add 80% of the iron ore waste rock aggregate (1-3mm) into the mixer, add additional water (0.10% of the aggregate) to fully stir and moisten; then add 19.7% of cement a, 0.3% of dyeing agent, and then add water Stir (the amount of water added is 0.26 according to the water-cement ratio) for 4 minutes to obtain the surface layer slurry.

[0083] S3. First arrange the bottom material for initial pressing, then lay out the fabric, and at the same time carry out vibratory hydraulic pressure for 8s to obtain permeable bricks.

[0084] Among them, the mass ratio of the surface layer slurry to the bottom layer slurry is 0.5:6, the cloth thickness of the bottom material is 90mm, and the initial pressure is 50kn; the cloth thickness ...

Embodiment 2

[0086] S1. Add iron ore waste rock aggregate (3-5mm) 34%, (5-10mm) 45%, cement a 21%, add to the forced mixer, dry mix for 1min; then add water and stir (the amount of water added is based on the water-cement ratio Be 0.28) 4min, obtain bottom layer slurry.

[0087] S2. Add 81.2% of iron ore waste rock aggregate (1-3mm) into the mixer, add additional water (accounting for 0.10% of the aggregate) to fully stir and moisten; then add cement a18%, dyeing agent 0.3%, add water and stir (The amount of water added is 0.26 according to the water-cement ratio) for 6 minutes to obtain the surface layer slurry.

[0088] S3. First arrange the bottom material for initial pressing, then lay out the fabric, and at the same time carry out vibratory hydraulic pressure for 8s to obtain permeable bricks.

[0089] Among them, the mass ratio of the surface layer slurry to the bottom layer slurry is 0.5:6, the cloth thickness of the bottom material is 45mm, and the initial pressure is 50kn; the cl...

Abstract

The invention provides a permeable brick and a preparation method thereof. In the present invention, the integral permeable brick is designed as a two-part structure, that is, the surface layer part and the bottom layer part. The two parts are formed by different ingredients, wherein the surface layer raw materials include waste ore, cement, silica fume, additives and Water; the base material includes a certain proportion of waste ore, cement, iron tailings and water. The above-mentioned different raw material formulas are used to form the surface layer and the bottom layer respectively, which not only effectively utilizes industrial solid waste (waste ore and iron tailings), but also meets the performance requirements of permeable bricks to achieve high water permeability, high strength, and wear resistance. , Antifreeze effect.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a permeable brick and a preparation method thereof. Background technique [0002] Permeable bricks are a kind of permeable and breathing bricks, which have a strong water absorption function. When the brick body is full of water, the water will be drained underground. In the city, pavement paved with permeable bricks can easily replenish resources to the underground soil. Compared with ordinary cement, it is cleaner and reduces environmental pollution caused by cross-flow of rainwater. Permeable bricks can release water vapor when the surface water evaporates, increase air humidity, and provide a better growth environment for urban plant growth. Therefore, permeable brick is a new type of environmentally friendly building material born to solve urban surface hardening and maintain urban ecological balance. It has the characteristics of water permeability, high strengt...
