Example Embodiment

[0053] Example 1

[0054] Dry the river sludge with a moisture content of about 70% to a moisture content of 40%, take 50 parts, and mix it with 10 parts of construction waste (about 30% moisture content) with an average particle size of about 3mm, 80 mesh fly ash (water content) After mixing 10 parts of 80 mesh stone powder (about 25% moisture content), the moisture content of the mixture is controlled to about 40% through humidification and drying treatment, and then granulated by a granulator. Small particles, small particles are directly fed from the top of the ceramsite rotary kiln, the small particles fall into the ceramsite rotary kiln from the high-speed rotor, and the small particles fall through the 1200℃ high temperature zone in the kiln, immediately forming boiling and evaporating water. After expansion, the puffed particles are rotated out of the ceramsite rotary kiln body, forming a brown sludge ceramsite with a shape close to a sphere (shape like figure 1 Shown). ...

[0074] Example 2

[0075] Dry the industrial wastewater sludge with a moisture content of about 50% to 40%, take 40 parts, and then 80 mesh fly ash (about 30% moisture content) 15 parts, 80 mesh stone powder (about 25% moisture content) After 15 parts are mixed, through humidification and drying treatment, the moisture content of the mixture is controlled to about 35%, and the granulator is granulated to make small particles. The small particles are directly fed from the top of the ceramsite rotary kiln. The high-speed rotor instantly falls into the ceramsite rotary kiln. The small particles fall through the high temperature zone of 1150℃ in the kiln, and immediately form boiling and evaporating water, which expands. The expanded particles are rotated out of the ceramsite rotary kiln to form The sludge ceramsite is brown, and the shape is close to the spherical shape. Characterization of the prepared sludge ceramsite sample: the density is 300.2kg / m 3 , The cylinder compressive ...

Example Embodiment

[0076] Example 3

[0077] The slurry with a moisture content of about 60% is dried to a moisture content of 40%, 50 parts are taken, and then mixed with 20 parts of 80 mesh fly ash (about 30% moisture content), and then humidified and dried to control the mixture The moisture content of the material is controlled to about 40%. The pellets are granulated by the granulator to produce small particles. The small particles are directly fed from the top of the ceramsite rotary kiln. The small particles fall into the ceramsite rotary kiln instantly from the high-speed rotor. Falling through the 1250°C high temperature zone in the kiln, boiling and evaporating water will immediately form and expand. The puffed particles are rotated out of the ceramsite rotary kiln body, forming brown sludge ceramsites with a shape close to a spherical shape. Characterization of the prepared river sludge ceramsite sample: the density is 289.7kg / m 3 , The cylinder compressive strength is 0.32MPa, the parti...

Abstract

The invention discloses a sludge ceramsite and ceramsite enhanced foam concrete self-insulation building block and a preparation method of the building block. Sludge ceramsite is obtained through puffing under high temperature after at least one of building rubbish, coal ash and mountain flour is mixed with sludge for granulating, the obtained sludge ceramsite has the characteristics of low density, high strength, low heat conductivity coefficient and high corrosion resistance, the ceramsite enhanced foam concrete self-insulation building block with low density, high strength, good heat insulation performance, low shrinking percentage, low water absorption rate, high impervious performance, good freezing resistance, good waterproof performance and durability, good sound insulation effect and good shock resistance and damping performance can be prepared by the obtained sludge ceramsite taken as an aggregate as well as sludge ceramsite, low calcium secondary coal ash, ordinary portland cement, detrital saltpetre, microcrystal inorganic materials, water, auxiliaries and the like through a physical foaming method; the preparation method is simple and low in cost, and meets industrial production.

Description

technical field [0001] The invention relates to a sludge ceramsite and a ceramsite-reinforced foam concrete self-insulating block and a method for preparing the block, belonging to the technical field of green building material preparation. Background technique [0002] The task of environmental protection in our country is extremely arduous, among which the treatment of thermal power generation, industrial waste from mining, river and lake sludge, urban domestic sludge, and construction waste is extremely difficult. On the other hand, the demand for housing construction is rapidly expanding due to economic development, the acceleration of urbanization and the improvement of people's living standards. In the construction industry, brick-concrete structures and frame-shear frame structures are still the main building systems, with clay solid bricks and other lightweight materials. It is still in the dominant position among wall materials. This kind of building masonry materi...
