Abstract
The present invention relates to concrete sticking materials. Spikes are anchored on a concrete sleeper or the whole road bed of concrete, or a concrete structure is repaired to improve the physical property of the sticking materials, save cement, and reduce manufacture cost. The present invention is characterized in that flyash or stone powder is doped in the sulfur and the sand of the known raw materials, a little naphthaline is additionally added, and the concrete sticking materials are made by mixing and decocting the sulfur, the sand, the flyash or the stone powder and the naphthaline. The concrete sticking materials are used for replacing cement and paraffin in the original mixing proportion.
Description
The present invention relates to a kind of material for binding concrete structure, be useful on concrete sleeper or the concrete integral channel bed railway spike anchoring or concrete structure repairing and use, this adhesives is according to the anchoring material development in State Scientific and Technological Commission's approval " concrete sleeper railway spike sulfur cement mortar anchorage " object of invention comes January nineteen eighty-two.
The concrete sleeper railway spike anchoring material of former invention is made up of sulphur, cement, sand, paraffin wax, and wherein the cement of being mixed because of moisture-free in the proportioning, so hydration can not take place, increases mixture intensity, and only plays filling effect.Paraffin wax is mixed by institute, because of proportion only is 0.765, in the process of boiling, often floats on the surface, can not uniform mixing in boiling material, also be difficult to bring into play its due effect.
The present invention's purpose is to develop a kind of new adhesives, and concrete sleeper is connected with railway spike firmly, improves resistance to compression, the tensile strength of anchoring material and reduces cost.
Invention is achieved in that earlier sulphur being broken into fritter puts into pot, under 120～170 ℃ temperature, and the fusing dehydration, the sand that to dry is poured in the pot slowly then, add flyash or stone flour again, and constantly stir, in pot, do not have again till the bubble generation.At this moment temperature is controlled between 135～145 ℃, adds the naphthalene of having smashed to pieces, stir, can water use.The proportioning of various materials is calculated by weight as follows:
1, sulphur: flyash: sand: naphthalene=1: 0.3～0.5: 1.3～1.5: 0.01～0.02
2, sulphur: stone flour: sand: naphthalene=1: 0.4～0.6: 1.3～1.5: 0.01～0.02
Adopt this proportioning, as anchoring material, compare with former invention proportioning materials, it is low to have cost, and anchor spike is solid and reliable, itself resistance to compression, tensile strength height, and save cement.
Adopt this proportioning, during as mending concrete structure body and function material, its intensity surpasses 400 grades of concrete standard figureses, so can be used for the mending concrete structure, when constructing in the winter time, because of its time of coagulation fast, so more faster time of coagulation than normally used epoxy resin mortar, and low cost.
Below further describe for example:
Manufacture test specimen by following proportioning, test its various physical and mechanical properties:
1, sulphur: flyash: sand: naphthalene=1: 0.4: 1.4: 0.015
2, sulphur: stone flour: sand: naphthalene=1: 0.5: 1.4: 0.015
Wherein main relevant material specification is as follows:
Title material place of production unit weight proportion fineness
Flyash Beijing Shijingshan 0.763kg/l 1.147 crosses 0.075mm and tails over 8.9%
Stone flour Xinxiang 1.2kg/l 2.54 crosses 0.15mm and tails over 50%
The physicals of various proportionings is as follows:
4 railway spike withdrawal resistances of proportioning numbering ultimate compression strength tensile strength
The 1(fly ash) 56390kpa 6747kpa＞6t

Fatigue test, lower limit are taked 3 tons, and the upper limit is taked 6 tons, carry out the resistance to plucking test with 4 anchor spikes, and be all above 2,000,000 times, up to specification.The electric insulation test, proportioning of the present invention also can reach the requirement of former invention proportioning.
The economy of three kinds of proportionings is compared as follows:
The proportioning numbering is calculated its anchoring material expense (unit) by every kilometer 1800 sleepers
The 1(fly ash) 1174
2(mixes stone flour) 1190
3(is by former invention proportioning) 1336
General used starting material of epoxy resin mortar and the mixing ratio by weight thereof that uses of mending concrete structure is as follows:
Resins, epoxy: dibutylester: quadrol: cement: medium sand=1: 0.3: 0.1: 1.3: 6.5
