Abstract
The invention discloses a novel cement grinding aid. The novel cement grinding aid comprises the following components in parts by weight: 3-6 parts of polyol amine, 8-12 parts of anhydrous sodium sulfate, 4-7 parts of tri-isopropanolamine, 6-8 parts of water, 12-18 parts of organic ammonium salt, 3-5 parts of sodium tripolyphosphate, 4-6 parts of aluminum sulfate, 5-7 parts of sodium chloride, and 8-9 parts of potassium chloride. The cement grinding aid is in favor of increasing the sealing performance and permeability of a cement mortar, the mortar fluidity is good, caking property is strong, and the cement grinding aid is difficultly contracted and difficultly generates cracks.
Description
Technical field
The invention belongs to cement field, specifically a kind of novel concrete grinding aid.
Background technology
The primary raw material that existing cement grinding aid generally uses is by: triethanolamine (grinding aid), Nacl (causing chloride ion to exceed standard), Natrii Sulfas, Matrii Sulfas Exsiccatus (easily crystallization), it is uniformly mixed using flyash as carrier and produces, current a lot of grinding aid used by cement production enterprise acts primarily as production-increasing function, but the increase along with cement industry mixing material usage amount, and after national general-purpose cement new standard reversal normal silicate 32.5 cement that will perform, some cement plant production cost will rise.Therefore require to have a kind of mill output that can improve can improve again mixing material content and the grinding aid of strength of cement is badly in need of its product for cement manufacturers and is more become specification very much in the case of not changing existing process conditions, performance is more superior, mix control convenient, reliable, cost price is more rational, by improving cement quality to mixing suitable quantity of water cement grinding aids in grinding process, the novel concrete grinding aid of energy efficient.
Summary of the invention
In place of it is an object of the invention to for Shortcomings in above-mentioned technology, the present invention provides a kind of novel concrete grinding aid, can improve the density of cement slurry, permeability, make mortar good fluidity, and caking property is strong, be difficult to contraction, be not likely to produce crack.
The technical scheme realizing the object of the invention is as follows:
A kind of novel concrete grinding aid, it is characterised in that include that following components and each component are respectively as follows: polyhydric alcohol amine according to weight portion
3-6 part, anhydrous sodium sulfate 8-12 part, triisopropanolamine 4-7 part, water 6-8 part, organic ammonium salt 12-18 part, sodium tripolyphosphate 3-5 part, aluminum sulfate 4-6 part, sodium chloride 5-7 part, potassium chloride 8-9 part.
A kind of novel concrete grinding aid of the present invention, former grinding aid adds the excited species of trace make cement in hydration process with the Na+ in grinding aid, OH-, SO4-2 etc. excites modified material, under the strengthening modification of mechanization educational level, powder surface can form certain surface activity point, in hydration process these active sites preferentially participate in aquation send out should, the chemi-excitation material that the enhancing function of composite cement grinding aid is mainly in grinding aid and grog and the calcium mixing in material, silicon, aluminum etc. carry out chemical reaction, define and contribute to the chemical product that cement strengthens, cause the lattice defect of oxide in cement simultaneously, improve to rise and answer activity.Simultaneously to ordinary cement there are about 20%-40% do not give full play to hydration granule surface activity effect strengthen, activated particle in cement is made to increase on thus, cement early metaphase hydrated product increases, it is more beneficial for improving the density of cement slurry, permeability, making mortar good fluidity, caking property is strong, be difficult to contraction, be not likely to produce crack.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
A kind of novel concrete grinding aid, it is respectively as follows: polyhydric alcohol amine 3-6 part according to weight portion including following components and each component, anhydrous sodium sulfate 8-12 part, triisopropanolamine 4-7 part, water 6-8 part, organic ammonium salt 12-18 part, sodium tripolyphosphate 3-5 part, aluminum sulfate 4-6 part, sodium chloride 5-7 part, potassium chloride 8-9 part.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to the design of the present invention without creative work.All technical staff in the art, all should be in the protection domain being defined in the patent claims the most on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
