Description

Use green mud and Irish touchstone to make the composite Portland cement of mixing material
Technical field
The invention belongs to building field, relate to a kind of material of construction, specifically is a kind of composite Portland cement that uses green mud and Irish touchstone to make mixing material.
Background technology
Composite Portland cement (code name PC) is by the levigate hydraulic cementing materials of processing of mixing material, the proper amount of gypsum of Portland clinker, two or more regulation (composite Portland cement [abbreviation complex cement]); The total addition content of mixing material should be no more than 50% greater than 20% by mass percentage in the cement.The used blended material of composite Portland cement is to meet the granulated blast-furnace slag of GB203-2008 regulation at present; The pozzolana mixed material and the flyash that meets the GB1596-2005 regulation that meet the GB2847-1996 regulation; And the active addition of newly opening up according to the GB175-2007 appendix A; Do not meet cement additive and Wingdale, the sandstone of latent hydraulicity or the volcanical ash property of standard-required like iron-tion slag, refining ferrochrome slag isoreactivity mixing material and activity index; And the nonactive mixing material of newly opening up according to GB 175-2007 appendix A, like titanium slag etc.
Green mud is meant that caustic room alkali in the paper technology reclaims the waste that the back produces, if arbitrarily topple over, stacking or landfill, can cause great harm to environment: 1, take a large amount of soils; 2, polluted air; 3, pollute water system etc.Through retrieval, mix green mud and also do not see relevant report as the composite Portland cement mixing material.
Summary of the invention
The objective of the invention is to the deficiency of prior art and a kind of composite Portland cement is provided; With trade wastes such as the discarded corner building stones of measuring the flyash that is easy to get greatly, furnace bottom slag, basalt stone field and green muds is main mixing material; Cost is low, and production technique is simple, and the composite Portland cement of gained can satisfy composite Portland cement requirement in the GB 175-2007 general purpose portland cement standard; Can handle industrial residue in a large number; Help environment protection and energy-saving and emission-reduction, can improve the composite Portland cement early strength simultaneously, improve the workability of composite Portland cement.
The technical scheme that the present invention adopted:
A kind of composite Portland cement that uses green mud and Irish touchstone to make mixing material; Be earlier green mud to be dehydrated water ratio less than 1%; The Irish touchstone mine tailing is broken into particle diameter less than 50 millimeters rubble, and send into milling equipment then to carry out grinding to specific surface area be 330m with basaltic broken stone, green mud, gypsum, acvator and after cement clinker mixes 2/ kg~350m 2/ kg; Carry out drying treatment in the grinding process and use abrasive dust material water ratio less than 0.5%; Go out mill and obtain composite Portland cement; Wherein in butt, each component percentage ratio meter by weight is respectively: basaltic broken stone 5%~35%, cement clinker 50%~75%, green mud 3%~15%, gypsum 3%~8%, acvator 0.5%~5%, various component weight percentage summations are one of percentage hundred.
Said acvator is the mixture of organic cpds and mineral compound; Wherein organic cpds comprises a kind of in trolamine, tri-isopropanolamine, sodium formiate, calcium formiate, lime acetate, sodium acetate or the potassium acetate or more than two kinds, and mineral compound comprises a kind of in water glass, potassium silicate, Calucium Silicate powder, sodium sulfate, vitriolate of tartar, ferric sulfate, ammonium sulfate, yellow soda ash, salt of wormwood, volatile salt or quicklime, the active silica or more than two kinds.
