Abstract
The invention provides a slag cement excitation and reinforcement agent, which comprises (by weight percent) diethylene glycol 3-6%, triethanolamine 0.2-0.3%, dispersing agent NNO 0.5-1%, expanded perlite 4-8%, and early-strength admixture 85-92%. The agent can effectively increase the strength for slag cement.
Description
Technical field
The present invention relates to a kind of admixture that plays the grinding aid effect that adds when being used for cement grinding, relate in particular to a kind of toughener that can refinforced cement intensity.
Background technology
When producing cement, in cement clinker, add various blended materials usually respectively, carry out grinding again, obtain required cement.For example slag is exactly a kind of blended material commonly used in cement production, the adding of blended material can effectively reduce cement cost, but, increase along with the blended material consumption, strength of cement progressively descends, how to guarantee the quality of cement when improving the blended material consumption, be the emphasis of industry technician research always.
In the prior art, the multiple admixture that is used for refinforced cement intensity has appearred.Wherein, used salt in the multiple admixture, the interpolation of salt, early strength that can refinforced cement still, through discovering after a while, is added salt and can be produced detrimentally affect to the later strength of cement.It is trolamine that another kind is proved to be effective additives, and at present, for reaching certain cement reinforced effects, the addition of trolamine must be more than 2/10000ths of cement total amount, and the price of trolamine is higher, and this has just caused the raising of cement cost.
Therefore, if can obtain a kind ofly can when improving the blended material consumption, guarantee the admixture of cement intensity, can effectively reduce cement cost.
Summary of the invention
It is lower and can guarantee the cement intensifier of cement performance when improving the slag consumption that the object of the invention provides a kind of cost, to be suitable for preparing the needs of slag cement.
For achieving the above object, the technical solution used in the present invention is: a kind of slag cement excitation reinforcement agent by weight, comprising:
Glycol ether 3-6%;
Trolamine 0.2-0.3%;
Dispersing agent NNO 0.5-1%;
Pearlstone 4-8%;
Powdered hardening accelerator 85-92%.
In the technique scheme, described hardening accelerator is Sodium sulfate anhydrous.min(99).
Perhaps, described hardening accelerator is the mixture of Sodium sulfate anhydrous.min(99) and Tai-Ace S 150, and wherein, in the gross weight of toughener, Sodium sulfate anhydrous.min(99) accounts for 80-85%, and Tai-Ace S 150 accounts for 3-12%
The preparation method of above-mentioned slag cement excitation reinforcement agent is in glycol ether, trolamine, dispersing agent NNO adding pearlstone, to stir; Again the mixture that obtains is joined in the hardening accelerator, stir, promptly obtain required slag cement excitation reinforcement agent.
Wherein, pearlstone is a porous material, can adsorb liquid substances such as glycol ether, trolamine, dispersing agent NNO, also can carry out the grinding of appropriateness in whipping process; Through absorption, can obtain powder raw material, add again in the powdered hardening accelerator, stirring the slag cement excitation reinforcement agent that obtains is powder.In use, only need the cement bistrique mix this agent about 0.5% together grinding get final product.
Because the technique scheme utilization, the present invention compared with prior art has following advantage:
1. adopt slag cement excitation reinforcement agent of the present invention, can effectively improve the intensity of slag cement, after tested, under the constant situation of cement grinding mill processing condition, ultimate compression strength improved 3-4Mpa in 1 day, and ultimate compression strength improved 4-6Mpa in 3 days.
2. toughener of the present invention is a powder, and cost is low, and is easy to use.
Embodiment
Below in conjunction with embodiment the present invention is further described:
Embodiment one: 5 kilograms of glycol ethers, 0.3 kilogram of trolamine, 1 kilogram of dispersing agent NNO are added in 7 kilograms of pearlstones, stir; Again the mixture that obtains is joined in 80 kilograms of Sodium sulfate anhydrous.min(99), stir; Add 6.7 kilo sulfuric acid aluminium at last, stir, promptly obtain slag cement excitation reinforcement agent.The product that obtains is a powder.
In the present embodiment, glycol ether is a technical grade, and content is more than 85%; Trolamine is a technical grade, and content is more than 85%, and dispersing agent NNO is a technical grade, content 100%.
Adopt cement clinker 40-45%, gypsum 5%, slag 50-55%, mix the present embodiment product of 0.5% weight in addition at the cement bistrique, grinding can reach 42.5 class g cements such as grade.
Adopt cement clinker 30-35%, gypsum 5%, slag 60-65%, mix the present embodiment product of 0.5% weight in addition at the cement bistrique, grinding can reach 32.5 class g cements such as grade.
Compare test:
The benchmark group adds cement clinker 45%, gypsum 5%, slag 50%, does not add excitation reinforcement agent, and after tested, its 1 day intensity is 7.6Mpa, and 3 days intensity is 19.0Mpa.
Test group adds cement clinker 45%, gypsum 5%, slag 50%, adds the excitation reinforcement agent of the present embodiment acquisition of gross weight 0.5% in addition, and after tested, its 1 day intensity is 11.0Mpa, and 3 days intensity is 23.2Mpa.
As seen, the product of present embodiment acquisition can significantly strengthen the intensity of slag cement.
Embodiment two: 4 kilograms of glycol ethers, 0.3 kilogram of trolamine, 0.7 kilogram of dispersing agent NNO are added in 4 kilograms of pearlstones, stir; Again the mixture that obtains is joined in 91 kilograms of Sodium sulfate anhydrous.min(99), stir, promptly obtain slag cement excitation reinforcement agent.The product that obtains is a powder.
