Embodiment 1

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

Embodiment 2

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

Embodiment 3

[0077] Dry the mud with a moisture content of about 60% to a moisture content of 40%, take 50 parts, and mix it with 20 parts of 80-mesh fly ash (with a moisture content of about 30%), and then control the mixture by humidifying and drying. The moisture content of the material is controlled at about 40%, and it is granulated by a granulator to make small particles. The small particles are directly fed from the top of the ceramsite rotary kiln, and the small particles instantly fall into the ceramsite rotary kiln from the high-speed rotor. Falling through the 1250°C high temperature zone in the kiln, boiling and evaporating water are formed immediately, and the expanded particles are rotated out of the ceramsite rotary kiln, forming brown sludge ceramsite 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, and the particle size distribution is in the r...

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...
