Description
Technical field
The invention belongs to building materials technology field, relate to a kind of concrete and preparation method thereof, be specifically related to a kind of green mud and white clay of using as normal concrete of adulterant and preparation method thereof.
Background technology
Concrete refers to gather materials with gelling material (such as cement), sand, masonry, cooperates by a certain percentage with water (adding or do not add water reducer and adulterant), and through stirring, moulding, maintenance and get, be one of contemporary topmost civil engineering material.For workability or the rear concrete performance of sclerosis of improving the normal concrete mixture, when concrete-agitating, mix levigate mineral material---adulterant, with replacing partial cement, reduce cement consumption.The character of adulterant and quantity affect concrete intensity, distortion, hydration heat, impermeability and color etc.The normal concrete adulterant is mainly used natural mineral raw and industrial residue (second class powered coal ash, GBFS, slag micro powder) etc. at present.
Melt after the black liquid burning is dissolved in warm water or the rare white liquid, forms green liquor.Causticization is reacted green liquor and lime exactly, the yellow soda ash that boiling is not played active function is transformed into sodium hydroxide, sending of the strong white liquor slurry workshop that produces after the reaction is as cooking liquor, rare white liquid send furnace room, sediment---the white clay that reaction generates, through filtering clarification, remove behind the residual alkali with causticization generate residue---green mud together is transported to solid waste disposal factory.
The pollutant discharge amount of paper industry occupies the whole nation the second, is only second to chemical industry.Green mud and white clay are as the by product in causticization stage, and growing amount is very large, can reach 4,500 ten thousand tons every year.The present mode of processing green mud and white clay remains stacking or landfill is main, and environment is exerted heavy pressures on.Utilize the research work of green mud to have been reported: to be mainly used in cement additive, chemical fertilizer etc.The problems such as but these utilizations to the paper pulp waste residue exist utilization ratio low, and technology is immature are so be difficult to consume in a large number this type of waste residue.Because a large amount of green mud and white claies is underutilized, and takies for a long time a large amount of soils, cause the soil alkalization, underground water is polluted, and harm humans is healthy, therefore how better to fully utilize the paper pulp waste residue, improving the added value of green mud and white clay, is the technical problem that needs to be resolved hurrily.
Through retrieval, use green mud and white clay to yet there are no relevant report as normal concrete of adulterant and preparation method thereof.
Summary of the invention
