Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of preparation method and using method of administering the foaming epoxy resin base grouting material of concrete floor empty drum.
Background technology
The factory building of large amount of building, workshop, garage, storage center all adopt concrete as ground, but concrete floor is poor owing to surface layer combines with basic unit, quality problems such as hollowing often occur.Traditional method is to cut after the hollowing position is cut with cutting machine, carries out surface construction again.Such treatment process has caused very big delay on the duration, not only take a lot of work, time-consuming but also owing to be difficult to guarantee new surface layer and basic unit can not occur hollowing once more so success ratio is not high, effect is also undesirable.Therefore, develop a kind of material and using method that is used to administer concrete floor empty drum, accomplish advanced technology, easy and simple to handle, raw material is easy to get, avoid doing over again, and is significant.Up to now, not domestic not seeing as yet about adopting foaming epoxy resin base grouting material to carry out the correlative study report that concrete floor empty drum is administered.
Summary of the invention
The objective of the invention is to solve the prior art defective, a kind of preparation method who administers the foaming epoxy resin base grouting material of concrete floor empty drum is provided, avoid the contraction of epoxy grouting material by foaming and intumescing, to guarantee that it can fully pour into the fill concrete floor empty drum, and satisfy the requirement of cohesive strength and other physical and mechanical propertiess, make concrete floor surface layer, injection material layer, the three of basic unit be bonded as one well, recover supporting capacity and functions of use, prevent that the ground surface layer is cracked, destruction comes off because of hollowing causes.
Another object of the present invention provides the using method of described foaming epoxy resin base grouting material.
Technical scheme of the present invention is as follows:
A kind of foaming epoxy resin base grouting material preparation method who administers concrete floor empty drum comprises the steps:
Take by weighing Resins, epoxy 100, thinner (5-100), solidifying agent (5-100), whipping agent (0-10), auxiliary agent (0-10) respectively according to mass ratio, under normal temperature, mix and make injection material, described Resins, epoxy is selected from a kind of in the bisphenol A type epoxy resin, described solidifying agent is a kind of in the normal temperature solidified amine curing agent, described whipping agent be can be in the whipping agent of foaming at normal temp a kind of.
The invention also discloses a kind of using method of foaming epoxy resin base grouting material of described improvement concrete floor empty drum, step is as follows:
Step 1 is holed at floor empty drum and location of cracks with boring bar tools such as electric hammers, in boring good hole grout nipple is installed, and the crack is sealed in order to avoid spillage when pouring into.
Step 2 is poured the foaming epoxy resin base grouting material for preparing the material-storage jar of pressure grouting equipment into, and the applying pressure grouting equipment pours into this injection material by grout nipple in concrete floor empty drum and crack.Perfusion is in proper order for to be begun by an end, and single hole carries out one by one continuously.After adjacent holes begins pulp, keep-uped pressure 3-5 minute, can stop this hole grouting, change and annotate adjacent grout hole.
Above-mentioned materials is filling and the certain expansion of foaming generation after being filled into the concrete floor empty drum position, makes the hollowing position closely knit.To reach the purpose of repairing hollowing.
The invention has the advantages that:
1. at concrete floor empty drum problems such as a large amount of factory buildings, garages, the present invention has developed a kind of foaming epoxy resin base grouting material of administering concrete floor empty drum.This material feedstock is easy to get, and easy construction does not destroy the concrete floor of original building.The foaming epoxy resin base grouting material for preparing is a kind of colourless substantially to brown transparent liquid, and physicals test results such as the density of surveying, viscosity see Table 1.The set time and the mechanical property of the variety control material by regulating solidifying agent are convenient to execute-in-place.The present invention has found a practicable method for administering concrete floor empty drum.
Table 1 is administered the foaming epoxy resin base grouting material physicals test result of concrete floor empty drum:
| Test event | Hybrid density (g/cm 3) | Mixing viscosity (25 ℃, mPas) | Working life (25 ℃, min) | Set time (25 ℃, h) |
| Performance | 0.9-1.2 | 10-5000 | ≥30 | ≥48 |
2. the injection material steady quality of the present invention's preparation is reliable, hollowing, problems of crack no longer occur through reaching full concrete floor after the perfusion, and the mechanical strength height, and cohesiveness is good, good endurance.The performance index of surveying see Table 2.
Table 2 is administered the foaming epoxy resin base grouting material The performance test results of concrete floor empty drum:
| Numbering | Test event | Unit | Test result |
| 1 | Ultimate compression strength | MPa | 5.2-50.8 |
| 2 | Tensile strength | MPa | 3.5-29.8 |
| 3 | Steel-steel tensile shear strength | MPa | 2.5-12.3 |
| 4 | Cubical expansivity | ％ | 0.1-100 |
3. the present invention provides a simple novel method for administering concrete floor empty drum, and with traditional cutting, reworking processing method such as cut and compare, the present invention is more time saving and energy saving, and easy handling is saved the duration.Resins, epoxy foaming back volume increases, and has saved pouring material when reaching good perfusion effect, has saved construction cost.
Hollowing is the common common faults in building concrete ground such as a large amount of industrial premises, garage, concrete base layer separates with surface layer after hollowing occurring, if untimely reparation, in the later stage use, because vehicle rolls, reasons such as weight accumulation, after the hollowing position of concrete floor is stressed gradually the cracking, warpage, the concrete at the serious position of pressurized also can be pulverized and come off.After adopting the epoxide resin based foam material injection hollowing of above-mentioned prescription, concrete base layer and the filling of surperficial screed-coat intermediary space is full, and be combined as a whole, and pouring material tool certain mechanical strength.Therefore, through the full concrete floor of perfusion hollowing, problems of crack appear no longer.
