Abstract
A kind of improved colored cement and manufacture method thereof, the present invention makes colored finish cement with cement clinker through the grinding that is mixed with the industrial sulphur slag that abandons in a large number, waste slag etc., thereby greatly reduces the cost of colored cement.The sharp useless amount of this cement is big, anti-aging, colourity is even, can be widely used in to construct floor, inside and outside Room finishing, historical relic ancient temple and common building.
Description
A kind of improved, particularly utilize waste residue etc. to make the colored cement and the manufacture method thereof of additive, belong to the cement material technical field.
At present, in construction industry,, often utilize colored cement to make finishing material for the needs of decorating.But common color cement is to be base-material with the white cement, adds pigment or is with the look mineral formulated.Mix iron oxide red pigment with white cement and be made into as red cement commonly used.Chinese patent the 5th volume discloses a kind of " colour cement produced by vertical kiln " (number of patent application is 87105484,1) No. 12, it adopts shaft kiln directly to calcine, make colored grog, in raw material, add the metal oxide and the corresponding industrial residue thereof of an amount of chromium, manganese or cobalt more respectively and make tinting material, adopt to add CaF
2With BaSO
4As composite mineralizer, mix setting accelerator NaCl, CaCl
2Making admixture with stearic acid or hide glue water makes.Above-mentioned colored cement, it constitutes cement base-material and a spot of colour developing (or dyeing) the thing two portions be divided into pectisation significantly, and cost is higher, and is not with look because of the cement body, passing that can be in time and wearing out, or make its color fade because of exposing to the weather.
On the other hand, along with the manufacturing development of sulfuric acid, increasing sulphur slag is thrown into nature.As 100 tons of small-sized vitriol workss of vitriolic of a daily output, a day waste discharge quantity of slag reaches 400 tons, they in big industrial production because of coal-fired waste slag of dishing out, serious pollution the environment of human survival.How to handle these waste residues, be the problem that people explore always.
The objective of the invention is to develop a kind of new, the cement of mass pigmentation, it, had both risen and had developed the color or dyeing as one of base-material that constitutes cement with band look waste residue etc., was again the indispensable part of cement.Simultaneously, also require this colored cement with intensity height, the big advantage of low, the sharp useless amount of cost.
The objective of the invention is on the basis of portland cement clinker, add raw materials such as sulphur slag, slag (band look) or painted shale and be mixed and form.Because these three kinds of raw materials that add all take on a red color or are coffee-like, so, when they add fashionablely as the part of cement, just make cement present corresponding color naturally; The sulphur slag is the waste material that abandons in the sulphuric acid process, and slag (redness) is (power plant) coal-fired gurry, and painted shale distributes wide and is easy to get, so, be that the colored cement nature cost that raw material is produced wants much cheap with them.
Above-mentioned three kinds of colouring materials can be separately and the portland cement clinker blending, also can be composite, and each component content is by weight:
1, cement clinker 40-80%;
Gypsum 1-5%;
Sulphur slag 15-55%;
2 cement clinker 45-80%;
Gypsum 1-5%;
Slag (redness) 15-50%;
3 cement clinker 70-90%;
Gypsum 1-5%;
Shale 5-30%;
4 cement clinker 40-70%;
Sulphur slag 20-50%;
Slag (redness) 0-30%;
Shale 5-10%;
Gypsum 1-5%;
When producing colored cement by above-mentioned prescription, roughly carry out in two steps, the first step is at first calcined out cement clinker by the traditional technology standard, second step, the colouring material of grog and the adding of above-mentioned desire is given homogenizing, then put into ball mill and carry out the grinding batching, can make colored cement.
Cement fineness: remove sieve with 0.08 millimeter square hole sieve, screen over-size is controlled at below the 4-12%.
It is fixed that the add-on of colouring material will be come according to required color, when requiring color dark, the amount that can add more greatly, otherwise, can add less amount.The ability that painted shale is adjusted color is bigger than other two kinds.
Several embodiments of the present invention below are provided:
(I) adds the scoriaceous facing cement of sulphur
Cement sulphur ore cream folding strength MPa/cm
2Ultimate compression strength MPa/cm

According to the facing cement that prescription provided by the invention makes, its compression strength reaches 33MPa(28 days) above rupture strength reaches 6MPa(28 days) more than. The setting time of cement, security performance etc. all reach the ordinary cement required standard. In addition, it also has following features:
1, by regulating the cement raw material ratio, can obtain desirable red or coffee-like cement.
2, sharp useless amount is big, can reach the 40-55% of cement output, thereby reduce the pollution of waste residue to environment, alleviates the cement raw material nervous situation that supply falls short of demand, has bigger social effect.
3, cost is low. Than other coloured cement, cost reduces by one times approximately, has bigger economic benefit.
4, ageing resistace is good, because the colouring material content among the present invention is big, colourity is even, and value of chromatism is little, and year in and year out, it is aging to be difficult for fading.
5, applied range not only can be done terrazzo, inside and outside Room decoration, historical relic ancient temple building, also can work as general cement and use.
6, sulphur slag etc. except playing coloration, because it has certain activity, can absorb the FCaO in the clinker in cement, improves the stable qualification rate of cement, improves intensity, improves cement performance.
