Embodiment 1

[0008] Take 44kg of cement; 13kg of fly ash; 14kg of river sand; 27kg of water; 2.15kg of 10% foaming agent aqueous solution; 0.12kg of 10% foam stabilizer aqueous solution. After stirring, foaming, forming and cutting, the sound-insulating block is made. The obtained foam block is detected, and its average sound absorption coefficient is greater than 0.4.

Embodiment 2

[0010] Take 46kg of cement; 10kg of fly ash; 15kg of river sand; 27kg of water; 2.2kg of 10% foaming agent aqueous solution; 0.12kg of 10% foam stabilizer aqueous solution. After stirring, foaming, forming and cutting, the sound-insulating block is made. The obtained foam block is detected, and its average sound absorption coefficient is greater than 0.4.

Embodiment 3

[0012] Take 47kg of cement; 11kg of fly ash; 13kg of river sand; 27kg of water; 2.3kg of 10% foaming agent aqueous solution; 0.12kg of 10% foam stabilizer aqueous solution. After stirring, foaming, forming and cutting, the sound-insulating block is made. The obtained foam block is detected, and its average sound absorption coefficient is greater than 0.4.

Abstract

The invention provides a sound-insulating building block formula, belonging to the field of building materials. The sound-insulating building block formula is prepared from the following raw materials in percentage by weight: 44-47% of cement, 10-13% of coal ash, 13-15% of river sands, 27% of water, 2.15-2.3% of a 10% foaming agent aqueous solution and 0.12% of a 10% foam stabilizer aqueous solution. The sound-insulating building block is prepared by the following steps: stirring, foaming, moulding and cutting; and finally, airing and condensing to prepare a finished product. As the foam stabilizer is added into the sound-insulating building block, bubbles generated are hardly cracked and uniformly distributed in a moulded building block; the coal dust is a honeycomb structure, so that a better sound-insulating and waterproof effect can be obtained.

Description

technical field [0001] The invention relates to the construction industry, in particular to a formula for sound-insulating blocks. Background technique [0002] At present, the formula of soundproof bricks on the market is mainly clay, which is fired into hollow mud bricks, or the raw materials of the formula are mainly cement, sand, and limestone particles, and it is made into non-fired hollow cement bricks. The hollow wall brick made of this kind of material has a through hole in the middle, which is very prone to water seepage in the wall when used in construction; or the six sides are sealed, and the middle part is empty, so when nailing the wall nails to hang heavy objects, It is still inevitable that there will be looseness. Obviously, the waterproof performance and hanging force of the hollow bricks made of traditional raw materials are greatly reduced when the sound insulation is satisfied.
