Description
Technical field
The present invention relates to a kind of solid waste composite inorganic facing mortar and preparation method thereof, belong to construction wall decorative materials technology.
Background technology
Facing mortar is a kind of novel construction wall finishing material rising gradually in recent years, and its colour-change scope is wide, and moulding is abundant.This material and production technology thereof are studied and are started late at home, and domestic well-known facing mortar enterprise is all that introduction of foreign technology or joint form are produced at present.Facing mortar product is mainly comprised of cement, graded sand, filler, pigment and other admixtures, can be widely used in various construction walls surface and ceiling decoration.
Compare with tile decorative surface with existing coating ornamental surface, compare with finish coat prepared by the organic materialss such as coating, facing mortar has better matching and consistency.Compare with tile decorative surface, facing mortar layer thickness is only 1～3mm, and quality is light, during as Highrise buildings finish coat, can not occur falling brick phenomenon because of problems such as negative blast.Therefore, that facing mortar product not only has is weather-proof, stain resistant, intensity advantages of higher, and compares ceramic tile, glass curtain wall etc. and have the advantages such as light weight, with low cost, easy construction.In country, greatly develop under housing industrialization, the encouragement of low-carbon (LC) material of construction policy, facing mortar is more and more subject to society's favor.
But, also there is the easy accumulation of salt in the surface soil, be prone to aberration, connect some problems such as stubble and automatically cleaning ability in facing mortar in applying.Wherein, the material accumulation of salt in the surface soil refers to that facing mortar material is applied to behind construction wall surface, through after a period of time, metope there will be the phenomenon of crystal like salt efflorescence, can cause things such as making the coating originally decorated or paint by jack-up, no longer stick metope, peeling just occur, come off.
Material accumulation of salt in the surface soil problem is paid close attention in building decoration mortar field always.Cause the reason of the accumulation of salt in the surface soil: the main component of Portland cement is Calucium Silicate powder (CaSiO
3), in meeting water process, C
3s(3CaOSiO
2), C
2s(2CaOSiO
2) aquation is when generating C-S-H gel, can produce a large amount of Ca (OH)
2, due to Ca (OH)
2can be dissolved in water and form Free Ca
2+, the in the situation that of a large amount of existence of water, water just becomes flowing carrier, carries a large amount of Ca
2+pore by decoration mortar self is penetrated into mortar surface, arrives surperficial Ca
2+with airborne CO
2caCO is produced in reaction
3and be deposited in surface and form the accumulation of salt in the surface soil.
Therefore, finding and eliminating facing mortar accumulation of salt in the surface soil problem is key one step that advances facing mortar progress, can realize facing mortar technological revolution sexual development.
Slag and mineral hot furnace slag be as electrodes with slags after steel smelting (also claiming metallurgical slag), is the association solid waste that steel-making produces, and due to its poor stability, complicated component, is difficult to disposal and utilization, stacks in a large number and serious environment pollution, take valuable soil, city.How to solve this technical problem, " turning waste into wealth ", has been the focus of this area, is also that national Ministry of Industry and Information requires the main project breaking through " Industrial Solid Waste efficiently utilizes " during " 12 ".
Summary of the invention
