Problems solved by technology

[0005] 2. Increase the base load
[0006] 3. Increase economic cost
In the process of aggregate preparation, there will be uneven particle size, irregular shape, and continuous particles. Direct mixing will affect the uniformity of pores inside the block and indirectly affect the strength of the block.
[0011] It can be seen that it is necessary to ensure both the light weight of the block and the uniformity of the pores, and the existing preparation methods are difficult to meet the requirements of both.

Embodiment 1

[0053] Such as figure 1 Among them, a kind of preparation method of phosphogypsum cavity mold particle, comprises the following steps:

[0054] S1. Prepare ice particles; in a preferred solution, the particle size of the ice particles is 0.5 cm to 2.00 cm. Optionally, prepare ice particles with a silica gel plate mold 6. Such as figure 2 In this method, ice particles are prepared by using two layers of butted silicone plate molds 6. The silicone plate molds 6 are provided with grooves, and the two silicone plate molds 6 are fastened and connected to each other. Each groove is provided with an opening for water inlet. . Preferably, the interlocking grooves form a spherical shape. The cost of this solution is relatively low, and it is used for preparing ice particles in small batches.

[0055] Another alternative such as image 3 Among them, the mold ice roller device is used to prepare ice particles. The structure of the mold ice roller device is that the surface of the ...

Embodiment 2

[0069] On the basis of Example 1, such as Figure 6 Among them, a method for preparing hollow blocks by using the above-mentioned phosphogypsum cavity mold particles also includes the following steps: S4, using phosphogypsum cavity mold particles as aggregates to prepare lightweight concrete; preferably, phosphorus The gypsum cavity mold particles are used as graded aggregates. After using graded aggregates, the compressive strength of the light-weight blocks produced can be increased by 0.2~0.8MPa. Such as Figure 9 shown in .

[0070] S5. Pour the prepared lightweight concrete into the mold and compact it with a press; the pressure of the first press of the press is 1-5 MPa.

[0071] The preferred solution is as Figure 4 , 5 Among them, the structure of the mold is: the lower outer mold 10 is arranged on the bottom mold 12, and the inner wall of the lower outer mold 10 is provided with a plurality of detachable inner molds 11, and the upper mold 8 is slidingly matched w...

Abstract

The invention provides a preparation method of ardealite cavity mold particles and hollow building blocks, and relates to the field of novel building materials, and the preparation method comprises the following steps: preparing ice particles; coating the ice particles with ardealite dry powder, and curing to obtain ardealite hardened mold particles; coating the outer layer of the ardealite hardened mold particle wet water with cement dry powder to obtain a cement-coated mold particle; the ardealite cavity mold particles are obtained through the steps. Preparing lightweight concrete by taking the ardealite cavity mold particles as aggregates; pouring the prepared lightweight concrete into a mold, and compacting by a press machine; and demolding and curing to obtain the light building block. The light building block can be prepared through the ardealite cavity mold particles, and the strength requirement of the hollow building block can be met. And the compressive strength can also be improved through the graded phosphogypsum cavity mold particles.

Description

technical field [0001] The invention relates to the field of new building materials, in particular to a method for preparing phosphogypsum cavity mold particles and hollow blocks. Background technique [0002] With the increasing shortage of urban land, the demand for high-rise frame buildings is increasing. Lightweight blocks suitable for frame structures have become mainstream in the market. [0003] Compared with lightweight blocks, self-heavy blocks have the following problems: [0004] 1. Increase the component load. Excessive block weight in infill walls can lead to increased loads on vertical members such as columns, shear walls, and beams, requiring larger cross-sectional areas or higher strength materials. [0005] 2. Increase the base load. With the same base area, only buildings with lower storey height can be built. If the storey height is to be increased, the building base area will inevitably increase or a higher-level base type will be adopted. [0006] 3...
