Abstract
The present invention relates to a prorous building block containing fibrous gypsum, which has the technical indexes that density is from 350 to 450 kg/m<3>, pressure resistant intensity is from 0.5 to 10MPa, void ratio is from 25 to 40%, softening coefficient is more than or equal to 0.65, and sound insulation is more than or equal to 40 db. The present invention has the technical formula: 90 to 100kg of beta type calcined gypsum, 30 to 40kg of pozzolan cement, 15 to 20kg of expanded perlite, 15 to 20kg of macaloids, 3 to 7kg of fiber magnesium cement, right amount of setting retarder and 110 to 130kg of water. The present invention has the advantages of high softening coefficient, good water-resistant performance, light wall weight of unit area and good sound insulation performance. The product can be sawn, planned and nailed, the processability is good, and the intensity of the product is high. The present invention is suitable for interior work for regulating the indoor climate.
Description
The present invention relates to a kind of constructional materials, particularly a kind of Prorous building block containing fibrous gypsum.
Non-bearing wall body the earliest, material use loam brick always, and not only weight is big, and heat-insulating property is poor, and coefficient of thermal conductivity height, soundproof effect are also bad.
The purpose of this invention is to provide a kind of lightweight, low heat conductivity, the good Prorous building block containing fibrous gypsum of sound insulation value.
The present invention realizes by following scheme:
Prorous building block containing fibrous gypsum, its technical indicator is: density 350-450kg/m
3, compressive strength 0.5-10.0MPa, hollow rate 25-40%, coefficient of softening 〉=0.65, sound insulation 〉=40db, its technical formula is: β type plaster of Paris 90-100 kilogram, trass cement 30-40 kilogram, expanded perlite 15-20 kilogram, retarding agent: an amount of, water 110-130 kilogram.
The production technology of above-mentioned Prorous building block containing fibrous gypsum comprises following activities:
A. by technical formula various materials are added in the mixer and make slurry;
B. above-mentioned slurry is poured in the forming machine that has in the vibration, make it moulding;
C. moulded products is sent into the drying that heats up in the 150-170 ℃ of dry kiln;
D. treat moisture content≤6% o'clock kiln discharge, warehouse-in.
The present invention can be widely used in the interior infilled wall of framework engineering and the internal partition wall of esidential building, compared with prior art has the following advantages:
1. coefficient of softening height, water repelling property is good;
2. the wall weight of unit area is light, and sound insulation property is good;
3. product can be sawed, can dig, can follow closely, and processability is good;
4. the product strength height is used for indoor engineering and can regulates kryptoclimate.
Embodiment: technical formula: β type plaster of Paris: 95kg, trass cement: 35kg, expanded perlite: 18kg, kieselguhr: 16kg, nemalite: 4kg, retarding agent: 3kg, water: 120kg, each composition adds in the concrete mixer in will filling a prescription, and stirs 30 minutes, evenly, pour in the forming machine, treat to send in the dry kiln after its moulding, be warming up to 160 ℃, survey moisture content after about 60 minutes, be lower than at 6% o'clock, kiln discharge, warehouse-in.
