Abstract
The invention discloses a production method for a light porous ceramsite concrete acoustic board. The method comprises the steps of: (1) soaking ceramsite in water; (2) stirring raw materials uniformly to obtain concrete, with the raw materials including cement, ceramsite, a water reducing agent, fiber and water; and (3) putting the ceramsite concrete well stirred in step (2) into a mold, carrying out poking vibrating, compaction, pressure, atmospheric steam curing, demolding, and steam high pressure curing, thus obtaining the light porous ceramsite concrete acoustic board. According to the light porous ceramsite concrete acoustic board and its production method provided by the invention, the concrete volume weight can be effectively reduced, the load of a track sound absorption bridge deck is reduced, and the sound absorption effect is improved.
Description
Technical field
The present invention relates to noise abatement technical field, particularly relate to a kind of light porous haydite concrete acoustic board.
Background technology
Domestic communication noise abatement is generally by arranging sound barrier to realize, and acoustic current barrier kind is a lot, can be divided into organic and inorganic and metallic ring barrier three major types according to material.Inorganic sound barrier Typical Representative is glass fiber reinforced plastic sound barrier, and his weak point is that fast light, ageing-resistant performance and quality should not control, and cost is very high; Metallic ring barrier typical products is aluminium alloy sound barrier, and his such as attractive in appearance, the antiseptic property that has many good qualities is strong, is convenient to transport and installs; But cost is the highest, vibrational frequency is close with Vehicular vibration frequency, and deflection is large, and later stage safety coefficient is low, can not put things right once and for all, and later maintenance costly, uses so be not easy to spread.For above two kinds of materials, inorganic materials sound barrier has that cost is low, later maintenance expense is low, electrical insulation capability good, structural safety advantages of higher, but general inorganic materials is generally heavier, transport and difficulty of construction large, aesthetic measure is on the low side, therefore in use and extension process, is subject to some restrictions.
Summary of the invention
For overcoming the deficiencies in the prior art, the object of the present invention is to provide a kind of production method of light porous haydite concrete acoustic board, effectively can reduce concrete density, reduce the load of track sound-absorbing bridge floor, improve sound-absorbing effect.
In order to achieve the above object, the technical solution adopted in the present invention is: a kind of production method of light porous haydite concrete acoustic board, comprises the following steps:
(1) be soaked in water haydite 1-3 hour;
(2) obtain concrete by even for raw material stirring, described raw material comprises cement, haydite, water reducer, fiber, water;
(3) haydite concrete be stirred in step (2) being put into mould, through plugging and pounding, compacting, atmospheric steam curing, described light porous haydite concrete acoustic board can be obtained after form removal and vapor injection maintenance.
Described haydite is light high-strength haydite, and particle diameter is the continuous grading of 5-12mm, and unit weight is 400-800kg/m
3; Water reducer is N-type high efficiency water reducing agent; Fiber is trevira.
The proportioning of described raw material is by every cubic meter of concrete: cement 200-300kg, haydite 0.8-1.2m
3, water reducer 0.1-10kg, fiber 0.5-1.5kg, water 30-100kg.
In described step (2), concrete adopts forced mixer to stir, and churning time is 120-180s.
In step (3), atmospheric steam curing for carry out maintenance 2-3h at 50-90 DEG C; Vapor injection maintenance temperature 140-180 DEG C, carry out maintenance 5-7h under pressure 0.85-1.1Mpa.
In described step (3) before mould put into by the haydite concrete be stirred, smearing release agent in mould.
Beneficial effect: compared with prior art, the invention has the advantages that:
1) this product utilizes haydite resource as light skeletal, and high strength rating cement, as gelling material, is aided with the light porous haydite concrete acoustic board that the admixture such as trevira and water reducer carries out composite molding.Because the vesicular structure of haydite inside, the cellular concrete that itself and the composition of concrete admixture such as high-strength cement, high efficiency water reducing agent are formed on sound-absorbing effect comparatively common porous concrete acoustic panel have greatly improved; Again because haydite unit weight is at 400-800kg/m
3, as light skeletal, significantly reduce concrete unit weight, thus reduce the load of track sound-absorbing bridge floor, eventually reduce construction cost.The light porous haydite concrete acoustic board produced, the cubes concrete sample 28d ultimate compression strength of its 100*100*100mm reaches 8.0-10.0MPa, and folding strength reaches 3.0-4.0MPa;
2) owing to shaping in a mold, can be mass-produced and meet the product of user's requirement, and the component of some special constructions can be processed, the concavo-convex joint construction realizing being connected between plate body with plate body is provided with at the two ends of plate body, plate body has the recess corresponding with track, plate body upper surface is provided with groove.This acoustic panel is laid on ballast bed of track surface, easy for installation, and noise reduction is obvious, largely solves a difficult problem for non-fragment orbit noise reduction;
3) owing to have employed vapor cure, shorten the production cycle, site operation and wet trade greatly reduce, concrete spills the reduction that to disturb residents with noise, improve the intensity of acoustic board, accelerate mould turnover, thus reduce production cost.
