Description
Technical field
The present invention relates to industrial solid castoffs and assembled architecture field, more particularly to nickel slag sand for building and nickel slag
Powder uses strength cement-based grouting material and preparation method thereof with.
Background technique
Since late 1970s, although China's productivity dynamics are rapid, urbanization degree is gradually goed deep into, with
The reduction of demographic dividend, human cost is higher and higher, and China's building field encounters many difficulties.Therefore, assembled architecture because
The advantages that its construction speed is fast, short construction period, production cost are low, energy-saving and environment friendly, becomes following China or even the world
The inexorable trend of architectural development.
Strength cement-based grouting material is a kind of special representing form of concrete, using cement as major gelled material, is subject to high-strength
Degree fine aggregate and different function additive are formulated, and are had many advantages, such as that high fluidity, early strong fast, durability is good, are become existing
The indispensable component part of modern building field.China has gradually moved to maturity to the research of strength cement-based grouting material at present.Patent
CN107805019A discloses a kind of carbon nanotube enhancing superfine cement composite grout and preparation method thereof, utilizes carbon nanotube
Enhance the fracture toughness and pressure-proof and snap-resistent intensity of cementitious composite grouting material, grouting material obtained has micro-expansibility, Gao Liudong
The advantages that spending can adapt to all kinds of adverse weather conditions.Patent CN106495581A discloses the grouting material reinforced for road
And preparation method thereof, it uses discarded concrete, steel slag and iron tailings slag for primary raw material, substitutes a large amount of cement, reduce filling
The cost of slurry, while improving the workability of grouting material, have many advantages, such as upper flow regime, high-strength, crack resistance.Patent
CN105198295A disclose it is a kind of using quartz sand and steel slag as the cement grout material of aggregate, the invention has used a lot of steel slag,
Achieve the purpose that turn waste into wealth, energy-saving and emission-reduction.
During nickel slag is nickel metal smelt, molten state nickel slag is extremely cold through natural air cooled or water-sprinkling and the granulated blast-furnace that is formed
Waste residue has SiO on element composition2, the features such as content of MgO is high, and itself has certain micro-expansibility.Compared to adopting
The nickel slag obtained with air cooling way, water quenching nickel slag have a large amount of vitreum, have certain gelation activity after multiple stage crushing.
Nickel solid impurity particle porous surface pattern can be combined preferably with other powders simultaneously, reduced filling cost, improved filling quality,
With good Social benefit and economic benefit.At this stage, mainly there is cement mixture in China to the resource utilization of nickel slag, mixes
Solidifying soil admixture, building block and steaming pressing product, valuable metal extraction, devitrified glass etc., achieve better hair
Exhibition, currently, nickel slag be applied to strength cement-based grouting material research and production application practice it is less, by nickel slag sand be put into ball mill carry out
Available nickel ground-slag after ball milling, nickel ground-slag can substitute cementitious material after guaranteeing certain fineness and use, even if having at present
Using nickel slag also to lead in strength cement-based grouting material, nickel slag sand to be used is temporarily unmanned to use nickel ground-slag as cementitious material, by the two
It is used in mixed way, does not have more, therefore, develop a kind of nickel slag cement base grouting material, have to the development of industrial society very important
Effect.
