Description

Composite blending material for concrete and preparation method thereof
Technical field
The present invention relates to a kind of is the composite blending material for concrete of main raw material with fly ash from burning city domestic garbage, flyash, slag micropowder, natural ore powder, belongs to material of construction fabricating technology field.
Background technology
Along with the quickening of urban construction, also increasing to concrete demand and consumption, concrete has become one of manufactured construction materials of contemporary consumption maximum.And in concrete several starting material, cement is again an indispensable part.Utilizing industrial residue and solid waste to prepare composite blending material for concrete, in order to replace a part of cement in the concrete, is the needs of useless admittedly resource utilization and recycling economy, also is the needs of concrete material scientific development.
Fly ash from burning city domestic garbage and cement are more approaching on main chemical compositions, and its main chemical compositions is: SiO 2, CaO, Al 2O 3, Fe 2O 3Deng.The flying ash fine particles, specific surface area is big, is alkalescence, has gelation activity, can be used as the feedstock production composite blending material for concrete, substitutes a part of cement.Simultaneously, China's burning city domestic garbage facture is obtaining application more and more widely, with regard to Shanghai, Pudong drives and handles the domestic refuse ability bridge garbage burning factory day about 1000 tons, handle the domestic refuse ability Xijiang River, Pu bridge rubbish factory's day about 1500 tons, the ignorant bridge garbage burning factory of planning to build and the day output of north suburb garbage burning factory are all about 500 tons.If have 2%～4% flying dust to generate by burning 1 ton of domestic refuse, then four factories operate simultaneously then that flying dust output has 100～180 tons every day, and year output reaches 4～60,000 tons.It is strong to burn a large amount of flying dust contaminatives that produce, and must deal carefully with.Flying dust mainly shows Organic pollutants such as heavy metal contamination, dissolved salt pollution and dioxin to the harm of environment.Harmless treatment requirement to flying dust, through carrying out landfill after the curing/stabilizing, yet arrange the processing costs of landfill very high, the disposing capacity of landfill yard is also limited, and the processing power of existing flying dust security landfill has been difficult to adapt to the quick growth of incineration of refuse flyash.Therefore,, seek the approach of suitable incineration of refuse flyash resource utilization, become the task of top priority that solves flying dust according to the theory of recycling economy.Is incineration of refuse flyash flying dust resource utilization approach preferably as one of raw material preparation composite blending material for concrete, can minimizing, resource utilization, harmless treatment flying dust, from environment, technology, economic dispatch angle flying dust is carried out stabilization treatment and recycling.
Another big source of pollution---industrial residue (flyash, slag) after treatment as active admixture, not only helps the concrete hydrating effect, strengthen degree of compactness and workability, lower porosity, improve concrete pore structure, and bigger effect is all arranged improving concrete durability.
Therefore, it is main raw material with fly ash from burning city domestic garbage, flyash, slag micropowder, natural ore powder etc. that the researchist invents a kind of, and the preparation composite blending material for concrete is produced concrete in order to a part of cement in the replacement concrete.
Summary of the invention
The purpose of this invention is to provide a kind of is main raw material with domestic waste, flying ash, flyash, slag micropowder, natural ore powder etc., be mixed with the composite blend that a kind of concrete is used, in order to the part cement in the replacement concrete, and make high performance concrete.
