Description
Technical field
The present invention relates to a kind of concrete complex mineral miserable with material and preparation method thereof, belong to the concrete works field.
Background technology
Concrete is one of topmost material of construction; Its purposes very extensively; Along with the continuous development of society and the requirement of national energy-conserving and environment-protective policy, the use of commerical ready-mixed concrete has obtained popularizing and has promoted, and its quality and use properties are also being updated, improved; Many new technologies are able to use, and the use of efficient additive and mineral admixture is exactly one of them.
Mineral admixture can instead of part cement in concrete, can play and reduce concrete cost and the effect that improves concrete performance, and cement is the high energy consumption product, needs to consume a large amount of Mineral resources; And mineral admixture is to be processed by industrial solid castoff, meets national resources comprehensive utilization policy, and cost is low, therefore; Under the prerequisite that guarantees concrete quality,, can practice thrift cement consumption with its instead of part cement; Reduce material cost, simultaneously, it can also play the reduction temperature rise in concrete; Improve workability, promote later strength, improve effects such as concrete inner structure, raising weather resistance.
The mineral admixture that provides in the market mainly is by flyash or the slag milling breeze after the certain fineness, no matter is on performance, sees economically that still its addition content all receives restriction to a certain degree when singly mixing.
Summary of the invention
The present invention is equipped with slag, liquid slag again for solid refuse such as the flyash that is equipped with the cogeneration papermaking enterprise, slag; By carrying out grinding after the suitable proportion collocation; Process and reach certain fineness, meet the correlation technique index, possess the more compounded mineral admixture of high surface.
The objective of the invention is to realize like this:
A kind of concrete compounded mineral admixture; It is characterized in that: constitute by flyash, slag, liquid slag, slag; Said each component ratio is by weight percentage: flyash 30-40, slag 30-40, liquid slag 5-15, slag 15-30; Said flyash is the former ash of from flue, collecting in heat power plant's coal-fired process, loss on ignition≤5%, moisture≤1%; Slag is the lime-ash that produces in heat power plant's coal-fired process, loss on ignition≤5%, moisture=0%; Liquid slag is the waste residue that refinery coal for replacing oil project produces, loss on ignition≤1%, moisture≤6%; The waste residue that slag forms for the ironmaking back, loss on ignition≤1%, moisture≤12%.
A kind of preparation method of concrete compounded mineral admixture is: flyash, slag, liquid slag, slag are prepared burden according to the above ratio; Evenly join in the ball mill; Grinding makes it to reach fineness and (uses the standard aperture to represent with percentage ratio as the square hole sieve screen over-size of 0.045mm; %)≤10, getting product appearance is black or grey black meal; Said grinding machine adopts and opens stream technology, and rotating speed is 22.4 rev/mins, divides two bins, and a storehouse grinding element is a steel ball, and two storehouse grinding elemenies are little forging.
Among the present invention, flyash is the former ash of from flue, collecting in heat power plant's coal-fired process, loss on ignition≤5%; Moisture≤1%, staple is SiO2, Al2O3, Fe2O3, CaO etc., is a kind of active pozzolanic materials that has; Slag is the lime-ash that produces in heat power plant's coal-fired process; Loss on ignition≤5%, moisture=0%, staple is SiO2, Al2O3, Fe2O3, CaO etc.; Liquid slag is the waste residue that refinery coal for replacing oil project produces, and forms even-grained black particle thing behind the quenching, loss on ignition≤1%, and moisture≤6%, staple is SiO2, Al2O3, Fe2O3, CaO etc.; The waste residue that slag forms for the ironmaking back, chilling forms after shrend, has higher lateral reactivity, loss on ignition≤1%, moisture≤12%, staple is SiO2, Al2O3, Fe2O3, CaO etc.
Flyash (be the former ash of from flue, collecting in heat power plant's coal-fired process, water ratio＜1% is a kind of active pozzolanic materials that has), slag (are the lime-ash that produces in heat power plant's coal-fired process; PM for particulate matter with certain particle size and low loss on ignition), liquid slag (waste residue for Ba Ling company coal for replacing oil project produces forms even-grained black particle thing behind the quenching), (be the waste residue that the ironmaking back forms, chilling forms slag after shrend; Have higher lateral reactivity) component batching by weight; (grinding machine adopts and opens stream technology, and rotating speed is 22.4 rev/mins, divides two bins evenly to join ball mill; One storehouse grinding element is a steel ball; Two storehouse grinding elemenies are little forging) middle grinding, (the 0.045mm square hole sieve tails over, and %)≤10 both gets to make it to reach fineness.Outward appearance is black or grey black meal.
The present invention combines the effective performance of multi mineral, and cost performance is high, and does not change the consistency of cement and admixture.Have better economic, environmental protection, social benefit, belong to Creative Science and Technology Co. Ltd's invention.
