Abstract

An acidic mixture contains granite and sulfuric acid sludge and can be used to prepare cement by adding it to silicate clinker. Said cement has features of high strength and performance and low cost.

Description

A kind of mixed material
The present invention relates in manufacture of cement, replace original alkaline blended material, join in the portland cement clinker, be used to prepare various cement with a kind of novel acidic mixed material.
The objective of the invention is to provide a kind of better mixing material, improve strength of cement according to this, improve performance, reduce cost, alleviate the alkali harm of gathering materials, improve concrete weather resistance.
This novel blended material with formations such as grouan, sulfate slags from the hard physical property of grouan, good Chemical Composition, is the very strong blended material of a kind of fine weather resistance.
Grouan, sulfate slag, scoriaceous chemical ingredients see Table 1
Table 1
From chemical ingredients, CaO content is less than 1% in the grouan, and CaO content reaches more than 40% in the slag, and slag belongs to alkalescence, and it is acid that grouan belongs to.CaO content adds acidic substance more than 60% in the alkaline water hard material in portland cement clinker, is effective to improving erosion resistance.Natural granite silicic acid metallic substance, itself seldom or do not have gelling and be worth, but its fine powder can be under normal temperature condition when having water to participate in and the slaked lime reaction, generates the compound with gelling.Warp and slag comparison seizure test, the result shows to have the same or better effect of slag.
Acidic mixed material used in the present invention, because of condition differences such as the places of production, chemical ingredients and performance are different, and material involved in the present invention must satisfy following standard-required: grouan, Loss<1.5%, SiO 2>60%, MgO<2%, alkali content<0.5%, the grouan of flesh pink is forbidden to be used among the present invention because of radioelement is arranged; Sulfate slag, Loss<5%, FeO>25%, Fe 2O 3<50%, MgO<7%, alkali content<0.5%.The working conditions of other blended materials is carried out by the countries concerned's standard and regulation.
The acidic mixed material is a kind of alternative high-quality blended materials to developing various novel silicate cements.Its intensity, weather resistance, acidproof, alkaline resistance properties is all good than alkaline blended materials such as slag, zeolites.
The detrimental impurity in this novel blended material such as the content of magnesium oxide, loss on ignition and alkali are very low, meet the requirement of high-quality blended material, are that a kind of sial content is up to the mineral more than 70~80%.This mineral are very wide in distributed in nature, exploitation easily, and steady quality, impurity seldom, cost is low again, is a kind of untapped high-quality blended material.
Mixed material of the present invention is by following component and/or form:
A, grouan 1~99%
B, sulfate slag 1~99%
C, fine coal dust 2~50%
D, slag 5~90%
E, Wingdale 5~20%
With the portland cement clinker proportioning of this blended material and different ratios, can be used for preparing the cement of different varieties.
The maximum doping quantity that this mixed material mixes in the portland cement clinker is to determine according to the maximum doping quantity that allows in each kind cement standard of country, under the prerequisite that does not change cement type character, improves cement quality.
According to national standard, the blended material maximum doping quantity is no more than 5% of cement quality in the II type silicate cement; The blended material maximum doping quantity is no more than 15% of cement quality in the ordinary Portland cement; The blended material maximum doping quantity is no more than 70% in the Portland blast, allows to replace slag with the material that is no more than 8%.The blended material maximum doping quantity is no more than 50% in the Portland pozzolana cement; The blended material maximum doping quantity is no more than 40% in the Portland fly ash cement; The blended material maximum doping quantity is no more than 50% in the composite Portland cement.The volume of blended material also is to add according to the maximum doping quantity that national standard is determined in the special cement.The blended material maximum doping quantity is no more than 15% when producing moderate-heat portland cement; The blended material maximum doping quantity is no more than 60% in the low heat portland blast-furnace-slag cement, allows to replace slag with the material that is no more than 30%.Road silicate cement blended material maximum doping quantity is no more than 10%.
Introduce grouan, sulfate slag etc. and make the novel acid blended material in cement, utilize existing processing unit basic condition, changing technical recipe can implement, and can improve cement quality, improves performance, can reduce cost again, and historical facts or anecdotes is executed easily, and is effective.
Specified below in conjunction with embodiment.But the present invention is not limited to this.
Embodiment 1
In portland cement clinker, add grouan, sulfate slag, Wingdale etc. and prepare ordinary Portland cement with proper amount of gypsum, its quality testing result such as table 2.
Table 2
Last table data show: in grog, mix grouan 5%~7%, and sulfate slag 3%~4%, Wingdale 3%~4% is pressed the GB175-1999 national standard, and it is feasible producing 42.5 ordinary Portland cements.
Embodiment 2
In portland cement clinker, add grouan, sulfate slag, Wingdale, slag etc. and prepare Portland blast with proper amount of gypsum, its quality testing result such as table 3.
Table 3
According to Portland blast GB1344-1999 standard code, the maximum of mixed material grouan replaces volume to surpass 8%, replaces the scoriaceous volume in back must not be less than 20%.Last table quality testing data show, mix 8% grouan and be better than slag under the equal conditions in grog.Therefore, it is effective to replace alkaline slag to make blended material with acid grouan.
Embodiment 3
In portland cement clinker, add grouan, sulfate slag, Wingdale, flyash etc. and prepare Portland pozzolana cement with proper amount of gypsum, its quality testing result such as table 4.
Table 4
As seen from the above table, make the Portland pozzolana cement blended material with grouan acidic mixed material, more effective than flyash, coal gangue, press GB1344-1999 standard production 42.5 Portland pozzolana cements and Portland fly ash cement, be a good method of guaranteeing the quality.
Embodiment 4
In portland cement clinker, add grouan, sulfate slag, Wingdale, coal gangue etc. and prepare composite Portland cement with proper amount of gypsum, its quality testing result such as table 5.
Table 5
Find out that from last table grouan is better than coal gangue, show that grouan is a kind of ideal acidic mixed material.
