[0035] b. Preparation of modified absorbent cotton filling block:

[0036] b 1 . Put the absorbent cotton in the cement mortar and soak it, so that the cement mortar fully soaks the absorbent cotton, and obtains the cement mortar soaked absorbent cotton. Specifically, the cement mortar consists of cement, fine sand and water, wherein the mass ratio of cement to fine sand is 1: (1-3), and the particle size of the fine sand is optimally 60-100 mesh. The cement mortar The consistency is 10-20, so that the cement mortar can enter the pore structure of the absorbent cotton, so that the absorbent cotton can harden and have a certain supporting strength.

[0037] b 2 . Soak the cement mortar with absorbent cotton and dry until hardened. For example, the absorbent cotton is soaked in cement mortar for 10-48 hours, then taken out, drained and dried naturally until the cement mortar in the absorbent cotton solidifies and hardens.

Embodiment 1

[0051] Cement is used as an adhesive, a mixture of coarse sand, fly ash, and crushed construction waste is used as a supporting aggregate, and a foaming agent is used as a pore-forming agent to form a permeable skeleton 100 by using a mold. The thickness ratio of the bottom, water-retaining part and top of the permeable skeleton is 1:1:1. A large water-retaining chamber is set in the water-retaining part, and the water-retaining chamber is filled with modified absorbent cotton filling blocks. The modified absorbent cotton filling block is prepared by the following method: the waste sponge is placed in cement mortar and soaked for 48 hours, so that the cement mortar fully soaks the waste sponge to obtain the cement mortar soaked absorbent cotton; the cement mortar soaked absorbent cotton is naturally drained, Naturally dry until the cement mortar is solidified; according to the shape and size of the water-retaining chamber, the hardened cement mortar is infiltrated with water-ab...

Embodiment 2

[0053] Cement is used as an adhesive, a mixture of coarse sand, fly ash, and crushed construction waste is used as a supporting aggregate, and a foaming agent is used as a pore-forming agent to form a permeable skeleton 100 by using a mold. The thickness ratio of the bottom, water-retaining part and top of the permeable skeleton is 1:2:2. A large water-retaining chamber is set in the water-retaining part, and the water-retaining chamber is filled with modified absorbent cotton filling blocks. The preparation method of the modified absorbent cotton filling block is the same as that in Example 1.

Abstract

The invention provides a permeable brick and a preparation method thereof, belonging to the technical field of sponge cities. The permeable brick includes a permeable skeleton and a water-retaining lining. The permeable skeleton is formed by pressing the permeable aggregate. The water-retaining lining is wrapped by the permeable skeleton. The water-retaining lining is made of modified absorbent cotton. The modified absorbent cotton is an absorbent sponge fully soaked in cement mortar. The water-retaining lining is integrated with the permeable frame, and there is no "hollow" sign, which ensures the strength of the permeable brick. The water-absorbing sponge maintains most of its water-absorbing and water-permeable properties, so that the permeable brick has a strong water-retaining function. The water-retaining lining made of modified absorbent cotton will not or hardly change the macroscopic structure of the water-retaining lining during the process of absorbing and releasing rainwater, thus effectively prolonging the life of the permeable brick and prolonging the duration of the water-retaining function of the permeable brick . At the same time, due to its own characteristics, the modified absorbent cotton endows the permeable brick with good moisture retention, noise reduction and sound absorption, and warmth and cold resistance.

Description

technical field [0001] The invention belongs to the technical field of sponge cities, and in particular relates to a permeable brick and a preparation method thereof. Background technique [0002] Permeable bricks refer to a type of ground paving material that has a high porosity of the bricks and rainwater can penetrate into the ground through the bricks. As an important part of sponge city construction, permeable bricks can absorb, store, infiltrate, and purify rainwater, which is of great significance for alleviating the pressure of urban flood discharge, reducing the phenomenon of rainwater overflow, and changing the local environment and climate. [0003] With the innovation and progress of technology, permeable bricks have been endowed with multiple functions, such as attaching photocatalysts on the surface of permeable bricks to realize self-cleaning of permeable bricks, changing the material of permeable bricks to enhance the strength of permeable bricks. The Chines...
