Embodiment 1

[0031] An autoclaved air-entrained concrete anti-seepage block, including ground quartz sand, cement, lime, and gypsum as the main base material, and aluminum powder as the foaming agent, and also includes a hydrophobic anti-seepage agent. The percentages are as follows, 50% of finely ground quartz sand, 16% of circulating mortar, 20% of cement, 11% of lime, 3% of gypsum, 0.08% of aluminum powder paste and 0.03% of hydrophobic anti-seepage agent can also be added. By using the internal anti-seepage agent to add hydrophobic groups to the product itself and the bubble wall, adding an internal waterproof agent to form a layer of bubble film on the contact surface between the bubble wall and water of the product, reducing the water seepage of the pores wall voids and capillaries, Improve the hydrophobicity of the air-entrained concrete pore wall, thereby improving its impermeability.

Embodiment 2

[0033] An autoclaved air-entrained concrete anti-seepage block, including ground quartz sand, cement, lime, and gypsum as the main base material, and aluminum powder as the foaming agent, and also includes a hydrophobic anti-seepage agent. The percentages are as follows, 50% of ground quartz sand, 16% of circulating mortar, 20% of cement, 11% of lime, 3% of gypsum, 0.08% of aluminum powder paste and 0.04% of hydrophobic anti-seepage agent can also be added. By using the internal anti-seepage agent to add hydrophobic groups to the product itself and the bubble wall, adding an internal waterproof agent to form a layer of bubble film on the contact surface between the bubble wall and water of the product, reducing the water seepage of the pores wall voids and capillaries, Improve the hydrophobicity of the air-entrained concrete pore wall, thereby improving its impermeability.

Embodiment 3

[0035] An autoclaved air-entrained concrete anti-seepage block, including ground quartz sand, cement, lime, and gypsum as the main base material, and aluminum powder as the foaming agent, and also includes a hydrophobic anti-seepage agent. The percentages are as follows, 50% of ground quartz sand, 16% of circulating mortar, 20% of cement, 11% of lime, 3% of gypsum, 0.08% of aluminum powder paste and 0.05% of hydrophobic anti-seepage agent can also be added. By using the internal anti-seepage agent to add hydrophobic groups to the product itself and the bubble wall, adding an internal waterproof agent to form a layer of bubble film on the contact surface between the bubble wall and water of the product, reducing the water seepage of the pores wall voids and capillaries, Improve the hydrophobicity of the air-entrained concrete pore wall, thereby improving its impermeability.

Abstract

The invention discloses an autoclaved aerated concrete anti-seepage building block and a preparation method thereof, the autoclaved aerated concrete anti-seepage building block takes finely ground quartz sand, cement, lime and gypsum as main base materials and aluminum powder as a foaming agent, and the autoclaved aerated concrete anti-seepage building block is characterized by comprising a hydrophobic anti-seepage agent, and the addition amount of the hydrophobic anti-seepage agent is 0.03-0.05% of the total amount by weight. The method comprises the following steps: mixing the components, stirring, standing, cutting, and curing for 10-12 hours at the high temperature of 180-200 DEG C and the high pressure of 10-12 standard atmospheric pressure to prepare the autoclaved aerated concrete anti-seepage building block. The invention relates to a sand aerated impervious concrete wall which has an impervious function and can not meet the waterproof and impervious requirements of a building in the existing sand aerated concrete wall.

Description

technical field [0001] The invention relates to an autoclaved aerated concrete anti-seepage block, in particular to an autoclaved aerated concrete anti-seepage block, which is mainly applied to the periphery of concrete structures, steel structures, and wooden structural components in self-insulation and energy-saving buildings The retaining wall can also be used for walls in wet parts such as bathrooms and kitchens in general interior walls. Background technique [0002] At present, there are many kinds of autoclaved aerated concrete blocks (boards) in the construction market, but so far there is no autoclaved aerated concrete blocks (boards) or other wall materials that can achieve Waterproof and anti-seepage requirements. Autoclaved aerated concrete blocks (boards) or other wall materials themselves are not waterproof and impermeable after the wall is formed, and the waterproof and impermeable requirements of the building are mainly met by painting waterproof materials. ...
