Abstract
The present invention discloses a method of replacing traditional engineering fine aggregate with fluidized-bed coal-gangue fluidized furnace slag (ash), which comprises application of natural sand and artificial sand in preparing building mortar in building engineering. The proportion of the fluidized-bed coal-gangue fluidized furnace slag (ash) used as an admixture for replacing the traditional engineering fine aggregate is from 20% to 100%. 2.5 to 13 portions by weight of fluidized furnace slag (ash), 1 portion by weight of cement and 0.2 to 1.1 portions by weight of lime paste are mixed together. The present invention solves the problem of the environmental pollution caused by the fluidized-bed coal-gangue fluidized furnace slag (ash), which exists for a long time. The present invention has the advantages of stable quality and low cost. On the premise that the requirements for the engineering discipline are satisfied, the present invention breaks people's traditional concept and opens up a new way for the comprehensive utilization of industrial waste slag.
Description
Affiliated technical field
The present invention relates to material of construction, particularly a kind of fluidized bed coal spoil boiling furnace slag (ash) that utilizes replaces traditional engineering fine aggregate, comprises natural sand and artificial sand, the application of preparation building mortar aggregate in construction work.
Background technology
Slag is the products of combustion of Industrial Boiler (as coal electrician industry), and boiling furnace slag then is the products of combustion of fluidizing furnace.Fluidizing furnace claims the bubbling bed again, belongs to first-generation fluid-bed combustion furnace.Boiling Combustion is a kind of combustion technology between the grate firing of solid combustion and pulverized coal friring, its combustion principle is: next is just so-called by air draught " fluidisation " by the curtain air effect that is blown under the stove hedge for burning crushing and classification particle, rolling up and down in the space of certain altitude above the stove hedge is similar to the motion of liquid boiling, and the burning graded particie carries out perfect combustion just under a kind of so violent, rambling " boiling " state.Therefore, fluidizing furnace can use difficult to burn materials inferior such as high ash, Gao Shui, low heat value, low-volatile just like coal gangue, and the thorax ash that boils is exactly a boiling furnace slag.The resulting boiling furnace slag of the coal gangue particle of boiling furnace combustion crushing and classification has low temperature (850 ℃-1000 ℃) and grills thoroughly innate advantage, thereby has certain activity and corrosion resistance preferably.
At present, the discharging of fluidized bed coal spoil boiling furnace slag (ash) has taken a large amount of soils, and environment there is serious pollution, simultaneously, masonry mortar be in the masonry project one of many uses, the material of construction that consumption is big, in all kinds of masonry structures, the building mortar role is exactly with the monolithic brick, stone or building block gluing constitute masonry integral body altogether, need a large amount of mortar and river sand etc. of using, soil erosion influence for river course etc. is serious, destroyed the eubiosis, and cost is also high, and fluidized bed coal spoil boiling furnace slag (ash) is to have certain intensity and construction workability, can guarantee that the intensity of whole masonry satisfies design, service requirements.
Summary of the invention
The invention provides a kind of fluidized bed coal spoil boiling furnace slag (ash) that utilizes and replace traditional engineering fine aggregate, comprise natural sand and artificial sand, the technology of preparation building mortar in construction work, this technology has solved for a long time, the pollution problem that fluidized bed coal spoil boiling furnace slag (ash) brings to environment, and steady quality, cost is low, under the condition that satisfies the engineering discipline requirement, broken the forbidden zone of people's traditional concepts, for a new road has been opened up in the comprehensive utilization of industrial residue.
Concrete technical scheme of the present invention is as follows:
The invention is characterized in: it is 20%-100% that fluidized bed coal spoil boiling furnace slag (ash) replaces the ratio of fine aggregate preparation building mortar.
The accumulation unit weight of fluid coal spoil boiling furnace slag of the present invention (ash) is 800-1400 kilogram/cubic meter.
The mean particle size range of fluidized bed coal spoil boiling furnace slag of the present invention (ash) is the 0.045-8 millimeter.
Fluidized bed coal spoil boiling furnace slag of the present invention (ash) with the weight proportion of cement, lime putty is: 2.5-13: 1: 0.2-1.1
The degree of sinking to of lime putty of the present invention (denseness) is 8-14 centimetre.
Cement of the present invention is ordinary Portland cement or silicate cement, comprise from label be 325 to label be 525.
Fluidized bed coal spoil boiling furnace slag of the present invention (ash) adds water and forces to stir with after cement, lime putty mix, and makes mortar, comprises masonry mortar, plastering mortar, waterproof mortar, jointing mortar, veneer mortar.
Fluidized bed coal spoil boiling furnace slag of the present invention (ash) can be selected the furnace bottom slag ash of climbing coal gangue power plant of coal (group) company 30,000 KW fluidizing furnaces for use.
The invention solves slag emission and environmental issue, waste residue fully utilized, have following innovation point:
(1) boiling furnace slag is batch, the typing " product " of coal gangue power plant burning classification coal gangue particle, source and physicochemical property are stable than traditional fine aggregates such as river sand, mountain sand, river sand, mountain sand etc. be can solve because of changed by many unfavorable factor such as the place of production, season, granular size and grating, silt content and organic impurity to cause the building mortar quality state unsettled technical barrier that fluctuates, thereby building mortar quality and construction quality guaranteed.
(2) boiling furnace slag has low temperature and grills thoroughly character, and slag granules has SiO
2, Al
2O
3Surface reaction can take place and improve granular boundary intensity in the isoreactivity composition, and performances such as mortar strength are had long-term favourable influence, improves the masonry project weather resistance.
(3) the boiling furnace slag masonry mortar has lower Young's modulus, favourablely under the bigger condition of the temperature difference alleviates and limits masonry crack development, helps improving the building aseismicity performance simultaneously, and this point is particularly useful for Panxi Diqu.
(4) having alleviated working-yard examination allotment of labor does and the quality control difficulty.Because physicochemical property, steady sources have reduced the working-yard examination and joined workload, can reduce working-yard engineering quality control difficulty, boiling furnace slag is easier to be accepted by vast construction management personnel and user for the sand technology.Under the condition that satisfies the engineering discipline requirement, broken the forbidden zone of people's traditional concepts, for a new road has been opened up in the comprehensive utilization of industrial residue.
