Description
Technical field
The invention belongs to building decoration engineering technology fields, and in particular to a kind of building decoration engineering environment-friendly type is compound to mix
Close material and preparation method thereof.
Technical background
The rapid development of China's steel and iron industry produces in production process while significantly improving people's living standard
Raw a lot of steel slag and slag also brings very big puzzlement to people's lives, and 300,000,000 tons of China's slag year yield or more at present, steel
100,000,000 tons of slag or more, their stockpiling is not only occupied valuable soil, is polluted to ambient enviroment, while being also a kind of huge
The wasting of resources.Contain in steel slag and slag largely with gelling mineral or glass state material as clinker constituent class, grinds
There is preferable gelation activity under suitable condition after fining-off.It is all that industrial residue provides in cement-based material all the time
The main object of source research on utilization.In recent years, the production scale of Chinese high performance mineral ground-slag and equipment have been in international
Forefront, the production of slag powders become completely new green building material industry also independently of traditional cement industry.And steel slag due to
It is difficult to grinding, the low reason of activity, utilization rate is very low, and a lot of steel slag is caused to accumulate, and pollutes environment, influences iron and steel enterprise's economy effect
Benefit.As country increasingly payes attention to ecological protection and circular economy, to the processing of steel slag using extremely urgent, using steel slag and
Slag synergistic effect, by the modification of additive, develops high value-added product, is a good approach.
Summary of the invention
The present invention is in view of the above-mentioned problems, provide a kind of using steel slag, slag as the building decoration engineering ring of main component
Guarantor's type composite blend and preparation method thereof, the admixture industrial solid castoff utilization rate is high and hydration reaction activity is high, both
Industrial solid castoff, which can be efficiently used, again can save the consumption of natural resources, environmentally protective.In order to achieve the above objectives, of the invention
Using following technical scheme.
A kind of building decoration engineering environment-friendly type composite blend, by the material composition of following weight percent:
Steel slag: 20wt%-30wt%
Hydrotalcite: 1wt%-5wt%
Bed of material stable material: 0.05wt%-0.3wt%
Magnesium fluosilicate: 0.1wt%-0.2wt%
Enhancing material: 0.1wt%-1wt%
Fiber: 0.1wt%-0.5wt%
Nano aluminium oxide: 1wt%-5wt%
Slag: surplus
The bed of material stable material refers to one of calcium saccharate, polyacrylamide, polyvinyl alcohol and polyglycereol or one
Kind or more.
Preferably, the bed of material stable material is made of polyvinyl alcohol and polyglycereol.
It is furthermore preferred that the polyglycereol is one or both of five polyglycereol and ten polyglycereol.
The enhancing material is one of sodium nitrate, iminodiacetic acid, aluminum sulfate or more.
Preferably, the enhancing material is iminodiacetic acid.
The fiber is one of coconut fibre, sisal fiber, ramee, basalt fibre or more.
Preferably, the fiber is made of coconut fibre and basalt fibre according to the weight ratio of 1-2:1.
Preferably, the fibre length is 1mm-3mm.
Building decoration engineering of the present invention is suitable for Vertical Mill production technology with environment-friendly type composite blend, comprising the following steps:
1) raw material is weighed by above-mentioned weight percent, grain diameter < 5mm is crushed to by crusher；2) raw material in step 1) is mixed
Vertical mill grinding is sent into after even to specific surface area in 420m2/kg-450m2/ kg, both the building decoration engineering environment-friendly type is compound
Admixture.
Building decoration engineering of the present invention is suitble to prepare using Vertical Mill technique grinding with environment-friendly type composite blend, material therein
Layer stabilizer plays adhesive action in the environment of grinding disc of vertical mill superheated vapor, stablizes the bed of material, makes rolling more sufficiently for grinding roller,
Raising rolls efficiency, with the reduction of temperature and subtracting for moisture of the good building decoration engineering environment-friendly type composite blend of grinding
It is few, peptizaiton is gradually played, the mobility of building decoration engineering environment-friendly type composite blend is increased, is conducive to powder concentrator work
Make, therefore improve the whole efficiency of vertical mill grinding building decoration engineering environment-friendly type composite blend, in building decoration engineering
When being applied in concrete with environment-friendly type composite blend, the bed of material therein, which stablizes component, can increase the cohesiveness of concrete,
Increase the ability of slurry cladding aggregate；Under Vertical Mill plus water soaking condition, magnesium fluosilicate has corruption to the vitreum in steel slag, slag
Dissolution is lost, more defects can be formed on steel slag, slag particle surface, increase reactivity；Hydrotalcite is a kind of with just
The metal oxide of charge, interlayer by the hydrogen bond of hydroxyl and electrostatic force association can with the trace metal ion in steel slag, such as
Calcium, magnesium, iron etc. generate complex reaction, make steel slag surface active and form network chelation structure, it is anti-to significantly improve steel slag aquation
Active is answered, in addition, hydrotalcite has certain alkalinity, to the building decoration engineering hydration reaction of environment-friendly type composite blend
There is certain facilitation；The main hydration products calcium silicates of cementitious material is nano-scale in concrete, nano aluminium oxide
It is added, on the one hand can play nucleus effect and be bonded more hydrated calcium silicates, on the one hand can fill small slit improves Behavior of Hardened Cement Paste
Pore structure, improve the mechanical property and durability of concrete；Enhancing material can promote building decoration engineering environment-friendly type multiple
The hydration reaction of admixture and cement is closed, early strength is improved.
Beneficial effects of the present invention:
(1) be conducive to iron and steel enterprise's Recycling Economy Construction.Helping iron and steel enterprise's building, " resource-product-waste-is again
The reaction type cyclic process in production-goods source " can more effectively be utilized resource, protection environment, be consumed with the smallest resource and environment
Cost obtains economic benefit and social benefit as big as possible, promotes iron and steel enterprise's solid waste comprehensive utilization of resources level and industry
The competitiveness of chain extension product.
(2) using effect is good, can improve concrete properties comprehensively.
(3) effects of energy conservation and environmental protection is good, can reduce cement consumption, and then reduce because of manufacture of cement bring resource, the energy
Consumption and pollutant discharge.
(4) significant economic benefit, iron and steel enterprise reduce waste residue land occupation expense, charges for disposing pollutants and become " useless " as " treasured " generation
Income；Cement is substituted in commerical ready-mixed concrete uses reduced production cost.
