preparation example Construction

[0017] The invention provides a method for preparing a compression-resistant and anti-shock aerated concrete block, wherein the preparation method includes:

[0018] (1) mixing lime, aluminum powder and water to obtain a mixture M1;

[0019] (2) Add early strength agent to mixture M1 to obtain mixture M2;

[0020] (3) Add cement, fly ash and foam stabilizer to the mixture M2 to obtain the mixture M3;

[0021] (4) Carry out initial maintenance after pouring the mixture M3 into the mold;

[0022] (5) After the initial maintenance is finished, demould and divide to obtain the block embryo body;

[0023] (6) Carry out steam curing to the block embryo body to obtain an aerated concrete block; wherein,

[0024] Relative to 100 parts by weight of the cement, the amount of the lime used is 50-200 parts by weight, the amount of the fly ash is 300-800 parts by weight, the amount of the water is 80-500 parts by weight, the The amount of the aluminum powder is 0.1-5 parts by weight, t...

Embodiment 1

[0039] Mix 80g of lime, 0.5g of aluminum powder and 150g of water to obtain mixture M1; add 2g of sodium chloride to mixture M1 to obtain mixture M2; add 5g of gypsum, 100g of cement, and 400g of fly ash to mixture M2 and 50g of foam stabilizer to obtain the mixture M3; pour the mixture M3 into the mold and place it in an environment with a temperature of 40°C for 1 hour of initial curing; after the initial curing is completed, demould and split at a cutting speed of 70mm / s , to obtain the block embryo body; vacuumize the block embryo body to a pressure of 0.07MPa, and keep it for 0.5h; then increase the pressure at a constant speed for 1.5h to a pressure of 1.2MPa, and keep the constant pressure for 6h; then reduce the pressure for 1.5h to 0.1 MPa, the compression-resistant and shock-proof aerated concrete block A1 was prepared.

Embodiment 2

[0041] Mix 150g of lime, 2g of aluminum powder and 300g of water to obtain mixture M1; add 5g of sodium chloride to mixture M1 to obtain mixture M2; add 50g of gypsum, 100g of cement, 700g of fly ash and 150g of foam stabilizer to obtain the mixture M3; pour the mixture M3 into the mold and place it in an environment with a temperature of 65°C for 3.5 hours of initial curing; after the initial curing is completed, demould and split at a splitting speed of 100mm / s , to obtain the block embryo body; after vacuumizing the block embryo body to a pressure of 0.07MPa, keep it for 1h; then increase the pressure at a constant speed for 2h to a pressure of 1.2MPa, then keep the constant pressure for 10h; then reduce the pressure for 2h to 0.1MPa, and make The compression-resistant and shock-proof aerated concrete block A2 is obtained.

Abstract

The invention discloses an anti-compression shockproof aerated concrete building block and a preparation method thereof, the preparation method is as follows: mixing lime, aluminum powder and water to obtain a mixture M1; adding an early strength agent into the mixture M1 to obtain a mixture M2; adding cement, fly ash and a foam stabilizing agent into the mixture M2 to obtain a mixture M3; pouring the mixture M3 into a mold for initial maintenance; after the initial maintenance, demoulding and segmenting to obtain a building block embryo; and curing the building block embryo with steam to obtain the aerated concrete building block. The aerated concrete building block comprises 100 in parts by weight of the cement, 50-200 in parts by weight of the lime, 300-800 in parts by weight of the fly ash, 80-500 in parts by weight of water, 0.1-5 in parts by weight of the aluminum powder, 20-200 in parts by weight of the foam stabilizing agent and 1-10 in parts by weight of the early strength agent, and can achieve the anti-compression shockproof effect.

Description

technical field [0001] The invention relates to the field of preparation of aerated concrete blocks, in particular to a compression-resistant and shock-proof aerated concrete block and a preparation method thereof. Background technique [0002] Aerated concrete blocks are widely used in daily production and life, and as a building material commonly used in daily life, its application in construction is extremely common. In life, with the continuous development of life, human factors other than natural factors such as earthquakes are also likely to cause vibrations on the ground, so the quality of building materials will also greatly affect the quality of buildings in real life. If the building materials are not good, the quality of the built buildings will also be greatly reduced. For example, if the building materials are not effective in shockproof, the buildings will be easily collapsed by the earthquake, which will cause huge losses. [0003] Therefore, it is an urgent ...
