Sintered brick: brick made of clay, shale, coal gangue or fly ash, made by molding and roasting at high temperature. Bricks used for masonry, loadbearing and non load bearing walls are collectively called sintered to the raw materials, they are divided into sintered clay brick, sintered fly ash brick, sintered coal brick and so sintered brick with a solid or void ratio
#0183;#32;The coal gangue was crushed, homogenized, milled and then pressed into green compacts. The dried compacts were sintered at different temperatures for 2 h. The obtained brick samples were characterized with Xray diffraction, scanning electron microscopy, and physicomechanical properties.
#0183;#32;The brick using coal gangue as the sole raw material sintered at 1200 #176;C possesses the optimal water absorption and compressive strength values (Xu et al., 2016). Although the fly ash brick has light weight and good thermal insulation performance, it cannot be used in building foundation works and walls in wet environments. Coal gangue brick
The chemical compositions of the Yellow River silt, coal gangue, airfloat algae slag and the effect in pavement brick making were analyzed. The main factors which effect the compressive strength of the pavement brick was researched. The best pavement brick factor level combination by orthogonal experimental design was determined. The effects of airfloat algae cement addition and sintering
As a new building material, sintered coal gangue selfinsulation block can not only make of coal gangue hollow brick from the Angle and tungstencobalt hard alloys after sintering.
Fired Bricks (including clay bricks, fly ash bricks, shale bricks, and coal gangue bricks) Made by sintering the clay materials: Compressive strength: 1030MPa; apparent density: kg/m 3; thermal conductivity: /(m*K); and frost resistance: 15 times: Walls, bases, columns, brick arches, etc.. Fired Porous Bricks
#0183;#32;When its the golden time for iron and steel industry, Mr. Xiong built a shaft furnace with about 200,000 red bricks to make pellet (crushing and sintering coal gangue into a ball).
As a new building material, sintered coal gangue selfinsulation block can not only make of coal gangue hollow brick from the Angle and tungstencobalt hard alloys after sintering.
#0183;#32;The brick using coal gangue as the sole raw material sintered at 1200 #176;C possesses the optimal water absorption and compressive strength values (Xu et al., 2016). Although the fly ash brick has light weight and good thermal insulation performance, it cannot be used in building foundation works and walls in wet environments. Coal gangue brick formed by internal combustion has strong strength and
#0183;#32;We found that the qualified composite sintered bricks with g/cm 3 of bulk density (BD), % of sintering shrinkage (SS), % of water absorption (WA) and MPa of compressive strength (CS) could be obtained by the optimal conditions: 54:30:10:6 mass ratio of iron ore tailings: coal gangue powder: shale: sewage sludge, 20 MPa of molding pressure, 1100 #176;C of sintering temperature
The sintered coal gangue cellular brick is an energy saving building materials extended on a big scale in our country at the market supply is not adequate to the demand,a few factories produce a unqualified brick and result in a large area of burst and crisp brick occurred in engineering and damage directly the engineering safety.
Many kinds of brick, according to the raw materials used for clay brick, shale, coal gangue brick, fly ash brick, lime sand bricks and slag brick; according to the production process can be divided into sintered brick and non sintered brick, which can be divided into non sintered brick brick, autoclaved bricks and autoclaved brick etc.; according to whether the holes can be divided into
The present invention discloses one kind of stone powder sludge sintering brick and its production process. The stone powder sludge sintering brick is produced with stone powder sludge from stone material producing process as main material, sludge from river, lake or sea, building waste clay or clay as adhesive, slag, coal slack, fly ash or coal as inner material, and through crushing
rate of using coal gangue, coal gangue to clay ratio, mineralizers, and process of forming and sintering. Using coal gangue of 75% and coal gangue to clay ratio of 3/1 made the mechanical properties optimal. The sintering temperature of 1370 #176;C was found to be optimal because
coking coal gangue emissions of 2,000 tons per wash 100 million tons of thermal coal, emissions of 15 million tons of waste rock volume [4]. The gangue comprehensive utilization of only 70%. China mainly for power generation, coal gangue brick, coal reclamation farmland, roads, underground filling, construction materials, chemicals and fertilizers.
