Abstract
The utility model relates to a repair structure of quick hardening cement, the quick restoration of the various damaged concrete of mainly used indicates a repair structure of quick hardening cement especially, the structure mainly including the hole groove of need repairing or filling with fill the quick hardening cement layer in the groove of hole, the quick hardening cement layer do not solidify for incompact powdered before the sclerosis, solidify the sclerosis back for cubic, the shape with need the hole groove phase -match repairing or fill, this repair structure of quick hardening cement has microdilatancy, low temperature condition intensity and brings into normal play, condenses that the sclerosis is fast, hour intensity is high and long -term intensity stability advantage such as normal.
Description
Technical field
The utility model relates to a kind of patching material structure being mainly used in the concrete quick reparation of various breakage, espespecially a kind of preparing structure of quick hardening cement.
Background technology
Quick hardening cement, also known as quick setting and rapid hardening dry-mixed mortar, is mainly used in rush repair engineering, underground construction, construction of tunnel, bolt-spary supports engineering, intercepts water the engineering such as leak stopping and road repairing.
Summary of the invention
For the requirement needing road surface rapid solidification stiff, the utility model is intended to openly a kind of patching material structure being mainly used in the concrete quick reparation of various breakage, espespecially a kind of preparing structure of quick hardening cement.
For achieving the above object, the technical solution adopted in the utility model is: a kind of preparing structure of quick hardening cement, described structure mainly comprises the hole groove that needs are repaired or filled and the quick hardening cement layer be filled in the groove of hole, be loose Powdered before the described non-setting and hardening of quick hardening cement layer, be block after setting and hardening, shape matches with needing the hole groove repaired or fill.
The rear powder mixture formed fully is mixed in proportion by bonding material layer, river sand layer, fortifying fibre layer and coagulant layer before described quick hardening cement does not solidify.
Described setting accelerator is tartaric acid, citric acid or boric acid.
After described quick hardening cement mixes with quartz sand in proportion, to add water stirring by metering, be filled into the block structure becoming after setting and hardening in the groove of hole and match with hole groove shape.
The beneficial effects of the utility model are embodied in: the preparing structure of this quick hardening cement has microdilatancy, cryogenic conditions intensity is brought into normal play, fast solidifying, hour intensity are high and longterm strength stablizes the advantages such as normal.
Accompanying drawing explanation
Fig. 1 is hole of the present utility model slot cross-section structural representation.
Fig. 2 is the cross section structure schematic diagram that the utility model repairs when filling hole groove.
Accompanying drawing mark illustrates: 1-cheats groove, 2-quick hardening cement layer.
Detailed description of the invention
Detailed description of the invention of the present utility model is described in detail below in conjunction with accompanying drawing:
As shown in the figure, a kind of preparing structure of quick hardening cement, described structure mainly comprises needs repairing or the hole groove (1) of filling and is filled in the inner quick hardening cement layer (2) in hole groove (1), be loose Powdered before described quick hardening cement layer (2) non-setting and hardening, be block after setting and hardening, shape matches with needing the hole groove (1) repaired or fill.
The rear powder mixture formed fully is mixed in proportion by bonding material layer, river sand layer, fortifying fibre layer and coagulant layer before described quick hardening cement does not solidify.
Described setting accelerator is tartaric acid, citric acid or boric acid.
After described quick hardening cement mixes with quartz sand in proportion, to add water stirring by metering, become after being filled into hole groove (1) inner setting and hardening and the block structure of hole groove (1) mating shapes.
Before construction, first clean needing to repair the hole groove (1) of filling, quartz sand or the whole heap of rubble are placed in pulverous quick hardening cement, to add water stirring by metering, be stirred in the hole groove (1) or crack that to be filled into after mixture has good mobility and caking property and to need to repair, after concordant of tooling revisions, within about 15 minutes, can be frozen into and the block structure of cheating groove (1) shape size and matching.
The utility model has that time of setting is fast, cementability good, intensity is high, the good and durability high with ordinary concrete matching, i.e. solidifiable in about 15 minutes, within 1 hour, can come into operation and (add stone on request and be made into concrete, under suitable construction temperature, within 1 hour, intensity reaches C30, and within 7 days, intensity reaches more than C50); Rupture strength is greater than C30 ordinary concrete (test method: detect rupture strength again after the supplementary irrigation that fractures in the middle of mortar) simultaneously, matching is good, volume stability is high, contract with dry rate is almost nil, coefficient of thermal expansion and ordinary concrete are almost consistent, and product is comprehensive, serviceability temperature scope is wide, can ensure that-5 DEG C to 45 DEG C can be constructed by normal temperature, durability is high, has good resistance to freezing and thawing and chemical resistance.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, the technician of the industry, under the inspiration of the technical program, some distortion and amendment can be made, every above embodiment is done according to technical spirit of the present utility model any amendment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
Claims (4)
