Embodiment 1

[0040] Such as figure 1 , figure 2 As shown, a gelatinized powder is used to produce high-strength lightweight aerated concrete blocks, including a body 1. One end of the body 1 is provided with a first opening 11 inside, and the other end is provided with a plug-in column 13. The diameter of the insertion column 13 is not greater than the aperture of the first opening 11, the length of the insertion column 13 is less than the depth of the first opening 11, and the peripheral wall of the first opening 11 is provided with The second opening 12.

[0041] Under this structural setting, during the solidification process of the block, the first opening 11 and the second opening 12 provide enough heat dissipation space to avoid the accumulation of reaction heat inside the block, especially the setting of the second opening 12 , which effectively improves the heat dissipation space inside the block. For the opening of the second opening 12, the existing technology cannot provide r...

Embodiment 2

[0047] A preparation method for producing high-strength lightweight aerated concrete blocks from gelled powder, comprising:

[0048] Step 1: pulping to obtain finished slurry;

[0049] Step 2: forming, pouring the finished product slurry into a mold to obtain a block embryo;

[0050] Step 3: Curing, steam curing the block embryo to obtain a block, the block includes a body 1, one end of the body 1 is provided with a first opening 11 inside, and the other end is provided with a plug-in column 13. The diameter of the insertion post 13 is not greater than the diameter of the first opening 11, the length of the insertion post 13 is less than the depth of the first opening 11, and the peripheral wall of the first opening 11 There is a second opening 12 on it.

[0051] Described step one comprises:

[0052] (1) iron tailings, quartz sand and water are mixed to obtain the first slurry;

[0053] (2) mixing cement, quartz sand, gelling powder, thermally conductive filler, foam stab...

Embodiment 3

[0066] According to the preparation method of Example 2, the difference is: 10000g of iron tailings, 8000g of quartz sand, 10000g of water, 8000g of cement, 5000g of gelatinized powder, 2000g of thermally conductive filler and 6000g of foam stabilizer to obtain block A2.

Abstract

The invention discloses a high-strength light aerated concrete building block produced from cementing powder. The high-strength light aerated concrete building block includes a body; a first open holeis formed in the body from one end to the interior of the body, an inserting column is arranged at the other end of the body, the diameter of the inserting column is not larger than the hole diameterof the first open hole, and the length of the inserting column is less than the depth of the first open hole; second open holes are formed in the peripheral wall of the first open hole. The inventionalso discloses a preparation method for producing the high-strength aerated concrete building block from the cementing powder. Compared with the prior art, the building block is provided with the first open hole and the second open holes, the requirement for sufficient heat dissipation can be met, the cracking problem is effectively solved, particularly, the second open holes are formed and matched with the first open hole, the size of the open holes in the building block is remarkably increased, and thus the heat dissipation space is effectively increased; the inserting column is inserted into a first open hole of another building block after building is completed, so that the two building blocks are connected more tightly, and thus the integrity and stability of a built wall can be remarkably improved.

Description

technical field [0001] The invention relates to a concrete block and a preparation method thereof, in particular to a high-strength lightweight aerated concrete block produced from gelatinized powder and a preparation method thereof. Background technique [0002] The cement hydration process is the main temperature factor in mass concrete. During the hardening process of concrete, due to the hydration of cement, a large amount of heat of hydration is generated in the first few days, and the temperature of concrete rises. However, the mass concrete structure is generally thicker, with poor heat conduction and relatively small heat dissipation, so a large amount of heat accumulates inside the structure. The internal heat of hydration is not easily lost, and the external concrete dissipates heat quickly. The temperature rise of the heat of hydration increases with the thickness of the wall (plate), and the concrete forms a certain temperature gradient. Regardless of the tempe...
