Abstract
A white masonry cement is prepared from white slag of blast furnace, lime stone and white cement through grinding and proportional mixing. Its advantages are high quality and low cost.
Description
Technical field
The present invention relates to a kind of cement products, more particularly, the present invention relates to a kind of white masonry cement and production method thereof.
Background technology
White masonry cement is mainly used in the construction of wiping one's face of construction work body of wall at present, conventional making method be with white cement clinker, Wingdale (powder), and proper amount of gypsum combined grinding in ball mill form, quality product is general, and energy consumption, cost are higher.Disclose a kind of " a kind of decoration special cement " among the application number 95107864.X, filling a prescription is: white cement clinker 40-55%, calcite or dry powder 40-50%, dihydrate gypsum 2-4%, talcum powder 0-2%.This method exists energy consumption height, defect of high cost too.
Summary of the invention
In view of above-mentioned condition, the object of the present invention is to provide a kind of white masonry cement and production method thereof.
The present invention is the excellent properties of deep processed product-white blast-furnace cinder micro-powder of utilizing existing Steel Plant solid waste, prepare a kind of novel white masonry cement, to satisfy the plastering of construction wall, batch embedding dual-use function, play environmental protection and waste utilization, energy-conservation, the effect that reduces cost simultaneously.
White masonry cement of the present invention is by white blast-furnace cinder micro-powder: 15～40%; Limestone powder: 30～70%; White cement: 10～40% form.
Wherein white blast-furnace cinder micro-powder: be blast furnace slag, the fine-powder that the drying grinding process makes, specific surface area is greater than 400m
2/ kg, whiteness is greater than 80.
Described limestone powder is a calcite, is the above white powders of 200 orders.
Described white cement is that the gypsum of white portland cement clinker adding 3%～6% mixes, is finely ground to 90% by 80 μ m square hole sieves.
The production method of white masonry cement of the present invention is:
Raw material consists of white blast-furnace cinder micro-powder: 15～40%; Limestone powder: 30～70%; White cement: 10～40%.After above-mentioned raw materials difference grinding, mix according to the above ratio.
Described white blast-furnace cinder micro-powder is the blast furnace slag by Steel Plant, the fine powder that the drying grinding process makes, and specific surface area is at 400m
2/ kg, whiteness is greater than 80.The white blast-furnace cinder micro-powder is widely used in the high performance concrete as concrete admixture with its good activity, workability and later strength always.
Described limestone powder can be raw material with the calcite, the white powder more than grinding to 200 order, main component: CaCO
3, in cement aquation, get up early and pretend usefulness.
Described white cement is that white portland cement clinker adds 3%～6% gypsum, the levigate hydraulic cementing materials of making, and 80 μ m square hole sieves tail over less than 10%, 28 day ultimate compression strength and can reach 62.5MPa, have pure white, fine and smooth, high-strength characteristics.
In traditional white masonry cement, limestone powder mixes as unique extra material and white cement, within the specific limits, limestone powder is got up early and is pretended usefulness, the part of excess plays filler effect, along with the increase of limestone powder volume, the intensity of product sharply descends, and is difficult to satisfy more and more higher service requirements.After mixing a certain amount of white blast-furnace cinder micro-powder, its inner Calucium Silicate powder material is at white cement hydrated product Ca (OH)
2Alkaline excitation under, bring into play its hydration activity effect, under the common hydration of white cement, limestone powder, obtained existing certain early strength, again the hydrated product of suitable later strength arranged.
Utilize the technology of the present invention to produce novel white masonry cement, blast-furnace slag, Wingdale, white cement are distinguished grinding, improved mill efficiency greatly, make each constituent materials can reach necessary fineness.Thereby give full play to the hydration of each constituent materials.Combined grinding is then because the grindability difference of each constituent materials, cause in the product this thin do not have levigate, should not be thin too thin, can not give full play to the effect of each constituent materials.Therefore the present invention has reduced the grinding energy consumption, has improved mill efficiency.
In addition, in prescription, increased this component of white blast-furnace cinder micro-powder,, the early stage and later strength of product of the present invention all has been greatly improved because it has good hydration activity.
Embodiment
Example 1
The making method of white masonry cement

2/ kg, whiteness is greater than 80.
Limestone powder is a calcite, is the above white powders of 200 orders.
White cement of the present invention is that white portland cement clinker adds 3%～6% gypsum and mixes, is finely ground to 80 μ m square hole sieves and tails over less than 10%.
2. in high-speed mixer that white blast-furnace cinder micro-powder, limestone powder, white cement is even by following mixed;
Raw material: white blast-furnace cinder micro-powder: 32%; Limestone powder: 32%; White cement: 36%
Than the index of high grade grade, whiteness reached the level of seconds in the white cement national standard during this routine cement was up to state standards fully, can prepare white masonry mortar, was used for the body of wall levelling and wiped one's face, and white helps later application and decorates.
Example 2
The making method of white masonry cement
With embodiment 1
Raw material: white blast-furnace cinder micro-powder: 15%; Limestone powder: 60%; White cement: 25%
This routine cement is up to state standards fully, and whiteness reaches the level of first grade in the white cement national standard, can be used as the material of main part that body of wall is criticized face putty.Higher whiteness helps later application and decorates.
Example 3
The making method of white masonry cement
With embodiment 1
Raw material: white blast-furnace cinder micro-powder: 40%; Limestone powder: 40%; White cement: 20%
This routine cement is up to state standards fully, and whiteness reaches the level of seconds in the white cement national standard, can be used as the material of main part that body of wall is criticized face putty.Higher whiteness helps later application and decorates.
