Abstract
The invention provides a sound-insulation building block, and belongs to the field of building materials. One cubic meter of the sound-insulation building block is composed of 280-300 Kg of cement, 80-120 Kg of mineral powder, 80-100 Kg of tailing sand, 185 Kg of water, 17-18 Kg of a foaming agent aqueous solution with the concentration of 10%, and 0.9 Kg of a foam-stabilizing agent aqueous solution with the concentration of 10%. The finished product is prepared by performing stirring, foaming, forming and cutting, and finally performing air-drying and coagulation. Foams generated by the sound-insulation building block added with a foam-stabilizing agent are not easy to rupture and are uniformly distributed in the formed building block. Fly ash has a honeycomb structure and is capable of obtaining relatively good sound-insulation waterproof effect.
Description
Technical field
The present invention relates to a kind of material of construction, be specifically related to a kind of sound insulation building block.
Background technology
At present, the acoustic brick on market is mainly earth and fires and form hollow and fire the burn-free cement brick that adobe or formula material are mainly cement, sand, limestone particle are made.Wall brick or the centre of this kind of hollow 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 object of this invention is to provide that a kind of formula is simple, environmental protection, with low cost and impermeable sound insulation building block.
Sound insulation building block of the present invention, is made up of following Raw material processing: cement 350 ~ 370kg; Flyash 80 ~ 100kg; River sand 100 ~ 120kg; Water 210kg; Concentration is the foaming agent water solution 17 ~ 18kg of 10%; Concentration is the suds-stabilizing agent aqueous solution 0.9kg of 10%.Wherein, described river sand selects mean particle size to be the fine sand of 0.2 ~ 0.4mm; The described suds-stabilizing agent aqueous solution is formulated by calcium stearate, alum, early strength water-reducing agent, accelerating chemicals and water; Described is processed as: stirring, foaming, shaping, cutting, last air-dry condensation obtains finished product.
The invention has the beneficial effects as follows, sound insulation building block of the present invention is raw materials used simple and easy to get, with low cost, produces environment friendly and pollution-free.Because sound insulation building block of the present invention adds suds-stabilizing agent, its bubble produced not easily breaks, and is evenly distributed in the middle of shaping building block, and bubble does not go here and there hole, while obtaining soundproof effect, can ensure water resistance again; Flyash has polynuclear plane, can obtain better soundproof effect.
