The invention discloses dedicated colloidal crystals for non-shrink super flow state cement mortar, which comprise the components as follows: lithium carbonate accounts for 1 to 4 parts by weight, poly carboxylic acid water reducing agents account for 3 to 10 parts by weight, boric acid accounts for 4 to 14 parts by weight, tartaric acid accounts for 0.5 to 1 part by weight, calcium sulfoaluminate powders account for 6 to 11 parts by weight, and coal ashes account for 67 to 80 parts by weight. A preparation method comprises the steps as follows: stirring (in step a), packing (in step b) and storage (in step c). The dedicated colloidal crystals adopt unique proportion, so that the early strength of the cement mortar is improved rapidly, time ranges from 1 to 3 hours, special environment such as ferrum, chromium and the like can be adapted, the compactability is improved, the number of gas pores is reduced, the fluidity is good, the slump is lower, microdilatancy and no shrink can be achieved, the final compression strength is improved from original C40 to more than C55, the low-temperature construction performance is improved, and the normal construction can be carried out under the temperature ranging from minus 10 to 15 DEG C.
Description
Technical field
The present invention relates to cement specialist additive technical field, especially relate to a kind of nothing and shrink big fluidised form sand-cement slurry special adhesive crystalline substance and sand-cement slurry.
Background technology
In the prior art; Cement adds water and stirs back one-tenth slurry; Can materials such as sand, stone securely gluing be maximum a kind of material of construction and the engineering materials of usage quantity in the ceramic together, be widely used in building, water conservancy, road, oil, chemical industry and the military engineering.
But, sand-cement slurry under than the high viscosity state, be difficult to keep fluidised form preferably, appear at easily in the site operation and add the on the high side or improper various construction quality problems that cause of maintenance of water because of custom.And, the sand-cement slurry of existing admixture additive, its final ultimate compression strength is C40, also can only in subzero 5 ℃ environment, construct.
Summary of the invention
The present invention is intended to solve the weak point of above-mentioned prior art, and then a kind of early strength that significantly improves sand-cement slurry is provided, and avoids the nothing of construction quality problem to shrink big fluidised form sand-cement slurry special adhesive crystalline substance and sand-cement slurry.
The objective of the invention is to realize through following technical scheme.
It is brilliant that a kind of nothing is shunk big fluidised form sand-cement slurry special adhesive, comprises the Quilonum Retard of 1-4 weight part, the polycarboxylate water-reducer of 3-10 weight part, the boric acid of 4-14 weight part, the tartrate of 0.5-1 weight part, the calcium sulphoaluminate powder of 6-11 weight part and the flyash of 67-80 weight part.
Further; It is brilliant that a kind of nothing is shunk big fluidised form sand-cement slurry special adhesive, is to be mixed and made into by the Quilonum Retard of 1-3.33 weight part, the polycarboxylate water-reducer of 3-10 weight part, the boric acid of 4-13.33 weight part, the tartrate of 0.83-1 weight part, the calcium sulphoaluminate powder of 5.83-11 weight part and the flyash of 66.67-80 weight part.
A kind of admixture does not have the sand-cement slurry of shrinking big fluidised form sand-cement slurry special adhesive crystalline substance, comprises 0# glue crystalline substance, cement and sandstone, and the brilliant addition content of said 0# glue is the 8-10% of cement weight.
A kind of admixture does not have the sand-cement slurry of shrinking big fluidised form sand-cement slurry special adhesive crystalline substance, comprises 0# glue crystalline substance, cement and sandstone, and the brilliant addition content of said 0# glue is the 3-5% of cement weight.
A kind of preparation method who does not have the big fluidised form sand-cement slurry special adhesive crystalline substance of contraction may further comprise the steps:
A. stir: put into mixing and blending machine to flyash and calcium sulphoaluminate powder by proportioning, put into Quilonum Retard, polycarboxylate water-reducer, boric acid and tartrate again, stir, it is mixed fully;
B. pack: the kraft paper plastic film bag that uses the moistureproof plastic film of liner is packing through step a mixture after being mixed;
C. store: the finished product bag after will packing is put into dry ventilation, avoids Exposure to Sunlight, guards against damp, waterproof.
Further, in said step a, the time of stirring is 5-8 minute.
Compared with prior art, beneficial effect of the present invention is: because the present invention has adopted unique proportioning, cause sand-cement slurry early strength fast lifting of the present invention, the time is 1-3 hour; Can adapt to special environment, like iron, chromium etc., improve compactness, pore reduces; Good fluidity, the slump is less, and microdilatancy does not have and shrinks; Final ultimate compression strength improves to be brought up to more than the C55 by original C 40, and the low-temperature construction performance improves, can be in subzero 10-15 ℃ environment normal construction.
The present invention has good education resistance; Under than the high viscosity state, still can keep fluidised form preferably; Effectively suppress and avoided adding the on the high side or improper various construction quality problems that cause of maintenance of water because of custom in the site operation; Simultaneously, can significantly improve early strength, final strength, flowability, micro-expansibility, education resistance ability and the low-temperature construction performance of sand-cement slurry, satisfy construction requirement.
During concrete the application, can be used for producing the sand-cement slurry of repairing material, ultra early-strength grouting material, bearing mortar, dry powder anchoring agent, railway spike anchoring agent and the requirement of fire-resistant temperature etc.
