Abstract
The invention relates to sound absorption building concrete comprising cement, wherein 10-15kg of magnesium silicate particles, 5-10kg of ceramsites and 10-15kg of calcium sulfate particles are mixed in every 100kg of cement. A sound absorption board made of the sound absorption building concrete is formed by the steps of mixing the cement, the magnesium silicate particles, the ceramsites, the calcium sulfate particles and water to prepare mortar, and then, solidifying and hardening, wherein the weight ratio of the cement to the magnesium silicate particles to the ceramsites to the calcium sulfate particles in the sound absorption board is 100: (10-15): (5-10): (10-15). The sound absorption building concrete provided by the invention has favorable sound absorption property and the sound absorption coefficient of 0.80-0.90 after being made into the sound absorption board; the sound absorption building concrete is easy to manufacture, convenient for construction, free of environment pollution problem and lower in cost.
Description
Technical field
The present invention relates to building material technical field, especially a kind of absorbing sound type building concrete and acoustic board and production method.
Background technology
Material of construction is the basic substance of construction work, and buildings needs to use various materials in constructing from the agent structure to decorations.Noise has become a kind of main environmental pollution, and the acoustic environment problem of buildings more and more is subjected to people's attention and attention.Selecting for use suitable material that buildings is absorbed sound and insulates against sound and handling is one of the most basic the most frequently used technical measures in the buildings noise control engineering.It is different with special emphasis that the target that solves with the sound insulation processing is handled in sound absorption, and absorbing sound and handling the target that solves is to weaken sound at indoor interreflection, also namely weakens indoor reverberant sound, and be the reverberation time perdurability that shortens reverberant sound; Under the situation of continuous noise, thisly weaken the reduction that shows as the room noise level, this point is for sound source and the sound-absorbing material space that exists together.And adjacent room is passed the sound of coming, sound-absorbing material also plays sorption, thereby is equivalent to improve the oise insulation factor of building enclosure.
Need adopt the absorbing sound type material to reduce sound interreflection inside in comparatively noisy rooms such as KTV, kino, meeting-place, adjust the reverberation time in conjunction with build, reach the requirement of different subjective sensations such as audition is clear, plentiful.At common local-style dwelling houses, also need the processing of insulating against sound, absorb sound, reduce outside noise to influencing in the room, build more comfortable human settlement.Present sound-absorbing material such as asbestos commonly used in building field, glass wool, rock mineral wool etc., though this class material has certain sound absorbing capabilities but sound insulation property is relatively poor, and above-mentioned materials is harmful, and is especially when constructing operation, bigger to the harm of human body and surrounding environment.Though the material of import has good sound absorption, sound insulation property, cost is too high.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the technical problem of sound-absorbing material of the prior art, a kind of absorbing sound type building concrete is provided, be easy to make, and can not produce pollution problem, cost is lower, has good sound absorbing capabilities.
The technical solution adopted for the present invention to solve the technical problems is: a kind of absorbing sound type building concrete, comprise cement, and be mixed with 10-15 kilogram magnesium silicate granule, 5-10 kilogram haydite and 10-15 kilogram calcium sulfate particle in per 100 kilograms of cement.
Further, for improving acoustically effective, the particle diameter of the magnesium silicate granule in the described acoustic board is 3 ~ 5 millimeters, and the particle diameter of the haydite in the described acoustic board is 5 ~ 10 millimeters.
A kind of acoustic board of being made by above-mentioned absorbing sound type building concrete, be mixed and made into the sclerosis of mortar after coagulation by cement, magnesium silicate granule, haydite and calcium sulfate particle and water and form, the weight ratio of cement, magnesium silicate granule, haydite and calcium sulfate particle is 100:10-15:5-10:10-15 in the described acoustic board.
Further, the thickness of described sheet material is 3 ~ 5 centimetres.
A kind of method of producing above-mentioned absorbing sound type building concrete has following steps: earlier 100 kilograms of cement are dropped in the whipping appts; Open and stir device; In whipping appts, drop into 10-15 kilogram magnesium silicate granule, 5-10 kilogram haydite and 10-15 kilogram calcium sulfate particle then in batches or simultaneously; Add suitable quantity of water while stirring, until stirring into the mortar shape, import and wait for sclerosis in the mould.
The invention has the beneficial effects as follows that absorbing sound type building concrete of the present invention has good sound absorbing capabilities after being made into acoustic board, sound absorption coefficient reaches 0.80-0.90, and is easy to make, easy construction, and the non-environmental-pollution problem, cost is lower.
Embodiment
Absorbing sound type building concrete of the present invention comprises cement, is mixed with 10-15 kilogram magnesium silicate granule, 5-10 kilogram haydite and 10-15 kilogram calcium sulfate particle in per 100 kilograms of cement.The particle diameter of the magnesium silicate granule in the described acoustic board is 3 ~ 5 millimeters, and the particle diameter of the haydite in the described acoustic board is 5 ~ 10 millimeters.
A kind of acoustic board of being made by above-mentioned absorbing sound type building concrete, be mixed and made into the sclerosis of mortar after coagulation by cement, magnesium silicate granule, haydite and calcium sulfate particle and water and form, the weight ratio of cement, magnesium silicate granule, haydite and calcium sulfate particle is 100:10-15:5-10:10-15 in the described acoustic board.The thickness of described sheet material is 3 ~ 5 centimetres.
A kind of method of producing above-mentioned absorbing sound type building concrete has following steps: earlier 100 kilograms of cement are dropped in the whipping appts; Open and stir device; In whipping appts, drop into 10-15 kilogram magnesium silicate granule, 5-10 kilogram haydite and 10-15 kilogram calcium sulfate particle then in batches or simultaneously; Add suitable quantity of water while stirring, until stirring into the mortar shape, import and wait for sclerosis in the mould.
Batching is introduced:
One, cement: powdery hydraulicity inorganic coagulation material, add water and stir the back and become slurry, can in air, harden or in water, better harden, and can gluing is together securely materials such as sand, stones.
Two, magnesium silicate granule: Magnesium Silicate q-agent is a kind of light mineral raw material, the employing dry process is made, product has good heat insulation, fire prevention, compressive property, it is desirable energy-saving building materials, be blended in back absorption moisture expansion in the cement, along with the sclerosis of cement, volumetric shrinkage after the dehydration, form hole, have good sound absorbing capabilities.
