Abstract
The invention discloses an enhanced grinding admixture of cement and the application. It solves the problem of environmental pollution generated by discarding the industrial waste such as ethyl cyanoacetate and methyl cyanoacetate and the problem of waste of the available components for a secondary use. It has the advantages that the formula is simple, the processing is brief, and it can make thebest of the useful components. The composition is that (wt.%): leftovers of the ethyl cyanoacetate or methyl cyanoacetate is 30-70, glauber's salt is 0-30, alunite is 0-20, lime is 0-10 and filling material is 20-60, weighing and blending uniformly.
Description
Technical field
The present invention relates to a kind of cement grinding aid, relate in particular to a kind of concrete reinforced abrasion-aided additive.
Background technology
Admixture in order to the cement enhancement is of a great variety, and inorganic and organic and inorganic and organic compound admixture are arranged.As the villaumite of some alkalies and alkaline earths, vitriol etc.; Organically as alcamines etc.In recent years, in order to strengthen its action effect, some composite admixtures had appearred again.The raw material of these admixtures mostly is salt industry and salt chemical engineering byproduct, because the source is complicated, kind is many, its difficult quality control often causes the admixture quality instability of being produced.
In ethyl cyanoacetate and methyl cyanoacetate process of producing product,, wherein contain ethanol 8% because its tankage are soluble substances, sulfuric acid 0.4%, nitrogen 0.3%, sodium 83%, cyanogen root GTM 76/1000000ths, the accumulation deposit serious environment pollution is especially to soil and contaminated water source.Mostly past is to carry out landfill, and not only pollution problem is really solved, and the composition that wherein has a utility value is wasted.
Summary of the invention
Purpose of the present invention is exactly to pollute the ring mirror in order to solve the ethyl cyanoacetate and the methyl cyanoacetate industrial waste that abandon at present, the problem that its beneficiating ingredient that can utilize once more is wasted, provide a kind of and have prescription simply, production process is easy, can make full use of the concrete reinforced abrasion-aided additive and the application thereof of the advantages such as useful component of this kind industrial waste.
For achieving the above object, the present invention adopts following technical scheme:
A kind of concrete reinforced abrasion-aided additive, its moiety is counted by weight, contain ethanol 8%, sulfuric acid 0.4%, nitrogen 0.3%, sodium 83%, 30～70 parts of the tankage of cyanogen root GTM 76/1000000ths, 0～30 part in saltcake, 0～20 part of alunite, 0～10 part in lime and flyash or other natural or 20～60 parts in artificial powder shape Mineral feedstock weighting material, their weighings, mix are evenly got final product.
Described weighting material be flyash or other natural or artificial powder shape Mineral feedstock, i.e. rubble powder, crushed slag, granulated blast-furnace slag.
A kind of application of concrete reinforced abrasion-aided additive is when mixing the system concrete, by weight: 60～100 parts of cement, 0～20 part of slag powders, 0～20 part in flyash, 0.6～1 part of admixture said ratio admixture.
A kind of application of concrete reinforced abrasion-aided additive whenever grinds 100 parts by weight of cement, admixture said ratio admixture 0.6～1 weight part.
The present invention is that concrete reinforced abrasion-aided additive and preparation production method thereof are produced in the main raw material preparation with the tankage in ethyl cyanoacetate and the methyl cyanoacetate production.Wherein, admixture mainly comprises tankage 30%～70%, saltcake 0%～30%, alunite 0%～20%, lime 0%～10% and the multiple weighting material such as the flyash etc. 20%～60% of ethyl cyanoacetate and methyl cyanoacetate.With tankage, saltcake, alunite, lime and the weighting material of institute's certainty ratio (as being crushed to for bulk less than 3mm or specific surface area greater than 300m
2/ kg) wait weighing, mix even, promptly obtain admixture of the present invention.
Admixture of the present invention is carried out the cement intensifier experiment, and its data are as follows:
The cyanogen root that is contained among the present invention with prescription in after each composition combined reaction, its content GTM is by original 76/1000000ths, be reduced to 8/1000000ths, simultaneously when grinding cement, because grinding machine surpasses 80 degree, reached 80 degree boiling points of cyanogen root, thereby the cyanogen radical content is further reduced, the finished product will be non-toxic substances.
Admixture of the present invention has mainly been used:
1) be used to mix system cement concrete or mortar:
Mixing 0.6～1 part of this admixture for per hundred parts can reduce by 10～25 parts cement consumption and substitute with mineral admixture;
2) be used for Cement Production:
(1) improve the cement quality grade and do not change the manufacture of cement proportioning, mix 0.6～1 part of this admixture for per hundred parts, the cement 3d that is produced, 28d intensity can increase a grade (former 32.5 grades of proportionings can be produced 42.5 class g cements);
(2) reduce the manufacture of cement cost and mix 0.6～1 part of this admixture for per hundred parts, can increase by 6～15 parts of blended material addition contents, the cement of production is identical with former proportioning or close;
(3) improve per hundred parts of soundness of cement and mix 0.6～1 part of this admixture, can improve and mill soundness qualification rate;
(4) shorten cement setting time and mix 0.6～1 part of this admixture for per hundred parts, cement setting time can shorten 0.5～1.5 hour.Help rapid construction and shorten demould time;
(5) improve cement mill output and mix this admixture for per hundred parts and grind cement for 0.6～1 part, mill output can improve 5%～10%.
The invention has the beneficial effects as follows: adopt admixture of the present invention, can improve cement performance, increase blended material addition content in the cement, reduce the manufacture of cement cost; This admixture has higher economic benefit and environmental benefit with useless (tankage in ethyl cyanoacetate and the methyl cyanoacetate production) sharp useless (flyash, slag, slag etc.); Admixture is turned waste into wealth, and has solved the pollution problem of ethyl cyanoacetate and the methyl cyanoacetate tankage in producing to environment, and has created benefit for factory; Admixture of the present invention utilizes the beneficiating ingredient in the tankage, belongs to inorganic organic compound additive; The main raw material stable components of admixture of the present invention, can guarantee join the quality of admixture.
