Description
Technical field
The present invention relates to a kind of composite blending material for concrete and preparation method thereof being primary raw material with nickel slag, manganese slag, burnedc lay, limestone, black stone, ardealite etc., belong to construction material fabricating technology field.
Background technology
Growth requirement along with green concrete, breeze in current concrete gel material, fly ash be in short supply and price rising all the way, causing concrete manufacturing cost to be stepped up, composite blend Substitute For Partial Binder Materials is an important research direction of modern concrete.
Mostly the application of current common admixture is to utilize one or both intergrindings such as house refuse bottom ash, quick lime, limestone, slag, slag micropowder, phosphorus slag and additive (mainly inorganic salts), and specific surface area is typically in 400～600m2Between/kg, replace the flyash etc. in Binder Materials, play effect of energy the economic benefit brought to mixing plant to a certain extent.
Existing scheme is in concrete use, can only the application of little scope, be not suitable for standardized commercial production, and it is applied in concrete, cause the slump-loss of fresh concrete relatively big and later strength reduces substantially, need the extra one-tenth increasing additive originally to meet concrete construction requirement, be so not easy in concrete substantial amounts of application.
Summary of the invention
It is an object of the invention to provide a kind of nickel slag manganese dreg concrete composite blend and preparation method thereof, the material by 6 kinds with not same-action obtains according to after certain material collocation grinding, for in concrete, under the premise ensureing concrete work performance, improve concrete intensity, and, the admixture of the present invention is less costly, breeze, cement etc. in concrete can be substituted, greatly reduce concrete cost, improve economic benefit.
The technical scheme is that
A kind of nickel slag manganese dreg concrete composite blend, is characterized in that: be made up of the raw material of following percentage by weight:
Nickel slag 3～10%, manganese slag 19～45%, burnedc lay 10～30%, limestone 30～60%, black stone 5～15%, ardealite 3～10%, the percentage by weight sum of above each component is 100%.
The selection of material and blend proportion in composite blend；Difficulty according to material, the feature of easy grinding carry out choosing material；And the contribution according to raw-material price and to concrete strength carries out the collocation of material ratio.
Preferably, it is made up of the raw material of following percentage by weight: nickel slag 5%, manganese slag 25%, burnedc lay 10%, limestone 50%, black stone 5%, ardealite 5%.

The preparation method that present invention also offers a kind of concrete composite blending material, is characterized in that, comprises the following steps:
1. weigh raw material by above-mentioned percentage by weight, control water into the mill less than 2%, enter the front material particles < 5mm of mill, if more than 5mm, it is necessary to broken；
2. by step 1. in put into ball mill after the raw material mix homogeneously that weighs, use 45 μm of square hole screens, control to tail over 15 ± 2%, namely obtain composite blending material for concrete.
Less than this fineness, the specific surface area of admixture is excessive, and water requirement is bigger than normal, and concrete loss is very big；More than this fineness admixture activation plays not out, concrete low strength.
Preferably, the described step 1. middle water into the mill mode less than 2% that controls is for inserting drying machine drying.
The invention has the beneficial effects as follows:
1. the compound composite blend of the present invention is by 6 kinds of inexpensive raw material intergrindings, controls rational granular size, utilizes limestone to improve early strength, reduces the absorption to additive and then reduce concrete loss；Manganese slag, nickel slag, burnedc lay is utilized to improve concrete later strength；Utilize ardealite to excite the raw-material activity of each component and deferred action, it is ensured that concrete service behaviour simultaneously.And need not additionally increase the consumption of additive when using in concrete, in equivalent replacement concrete under the premise of the Binder Materials of 20-50%, it is possible to meeting service behaviour, intensity improves more than 5MPa simultaneously.
2. the present invention make full use of various waste residue, with low cost, the indexs such as concrete service behaviour, mechanical property, durability and volume stability can be improved, it is possible to steady production, it is ensured that supply, energy-saving and cost-reducing and protection environment are significant.
3. remarkable in economical benefits (often side's concrete can bring the benefit of 15.2 yuan/side, and existing common admixture brings the benefit of 3.6 yuan/side) after using the composite blend of the present invention.
