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
The present invention relates to building trade, be specifically related to a kind of formula of sound insulation building block.
Background technology
At present, the acoustic brick formula on market is mainly clay, and is fired into hollow adobe, or formula material is mainly cement, sand, limestone particle, and is made into unburned hollow cement brick.Wall brick or the centre of the hollow that this kind of raw material is made are through hole, are applied to the situation very easily occurring wall leakage in building; Or six face seals, middle portion is empty, then, when hammering into wall nail and hanging weight, still unavoidably there will be loosening situation.Obviously, the Hollow brick be made up of traditional raw material is when meeting sound insulation, and water resistance, hanging force but greatly reduce.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of formula is simple, environmental protection, with low cost, meet the formula of water resistance and the strong sound insulation building block of hanging force simultaneously.
Sound insulation building block formula of the present invention comprises following raw material: cement, flyash, river sand, water, whipping agent, suds-stabilizing agent.Raw material consists of by mass percentage: cement 44% ~ 47%; Flyash 10% ~ 13%; River sand 13% ~ 15%; Water 27%; Concentration is the foaming agent water solution 2.15% ~ 2.3% of 10%; Concentration is the suds-stabilizing agent aqueous solution 0.12% of 10%.Wherein, described river sand selects mean particle size to be the fine sand of 0.2 ~ 0.4mm, and the described suds-stabilizing agent aqueous solution is formulated by calcium stearate, alum, early strength water-reducing agent, accelerating chemicals and water.
Because formula adopts above raw material, the invention has the beneficial effects as follows:
Major ingredient only comprises three kinds of materials: cement, flyash and river sand, and its formula is simple, and raw material environmental protection is easy to get.Owing to present invention adds suds-stabilizing agent, its bubble produced not easily breaks, and is evenly distributed in the middle of shaping building block; Flyash has polynuclear plane, can obtain better soundproof effect.
