Abstract

The invention discloses a material used for lifting a ballastless track bed. The material comprises the following ingredients in parts by mass: 300 to 500 parts of cement, 300 to 700 parts of quartz sand, 50 to 100 parts of ore slag micro powder, 50 to 100 parts of cenospheres, 20 to 40 parts of expansion agents, 3 to 12 parts of water reducing agents and 0.5 to 12 parts of defoaming agents. The material used for lifting the ballastless track bed has the advantages that newly mixed mortar is in a high flow regime (the fluidity is 20 to 30s); the sedimentation and the water excretion cannot occur even when the water quantity is great; in addition, the composite expansion agents are introduced; the early stage contraction can be well compensated; the shrinkage generated after the mortar hardening can be well compensated; the environment-friendly effect is achieved.

Description

A kind of non-fragment orbit bed lifting material therefor
Technical field
The invention belongs to engineering material technical field, it is related to a kind of non-fragment orbit bed lifting material therefor.
Background technology
Like product fresh paste poor fluidity, construction open hour are short；Intensity is not enough, no early-age plastic expansion etc. is asked Topic.
Content of the invention
In order to solve problems of the prior art, the invention provides a kind of non-fragment orbit bed lifting material therefor.
The purpose of the present invention is achieved through the following technical solutions: a kind of non-fragment orbit bed lifting material therefor, its component And mass fraction is as follows:
Preferably, described quartz sand for modulus of fineness isQuartziferous Machine-made Sand, described slag micropowder be s95 Or more level graining blast-furnace cinder micro-powder, described floating bead be the spherical flyash of i level.
Preferably, 330 parts of described cement, 650 parts of quartz sand, 75 parts of slag micropowder, 75 parts of floating bead, 25 parts of extender, subtract 1.2 parts of water preparation, 2.0 parts of defoamer.
Preferably, 350 parts of described cement, 650 parts of quartz sand, 65 parts of slag micropowder, 65 parts of floating bead, 27 parts of extender, subtract 1.3 parts of water preparation, 2.0 parts of defoamer.
Preferably, 310 parts of cement, 650 parts of quartz sand, 85 parts of slag micropowder, 85 parts of floating bead, 23 parts of extender, water reducer 1.2 parts, 2.0 parts of defoamer.
Preferably, 330 parts of cement, 650 parts of quartz sand, 0 part of slag micropowder, 150 parts of floating bead, 25 parts of extender, water reducer 1.5 parts, 2.0 parts of defoamer.
The medicine have the advantages that this non-fragment orbit bed lifting proprietary material fresh paste is in upper flow regime (fluidity)；I.e. Water usage is bigger than normal there is not sedimentation and bleeding yet, and introduces composite expanding agent, both can be well Compensate early-age shrinkage it is also possible to compensate well for the contraction of generation after slurry hardening, environmental friendliness.
Specific embodiment
The present invention is described further in conjunction with the embodiments.
A kind of non-fragment orbit bed lifting material therefor, its component and mass fraction are as follows:
Described cement is 42.5 grades of ordinary cements, and described quartz sand for modulus of fineness isQuartziferous mechanism Sand, described slag micropowder is s95 or more level graining blast-furnace cinder micro-powder, and described floating bead is the spherical flyash of i level, described expansion Agent is compounding extender, and described water reducer is polycarboxylic acid salt's water reducer, and defoamer is German import organic silicon defoamer p803. By material during use: water=100: (20 ± 3) are added into water and uniformly stirred use.
Wherein, 1, polycarboxylic acid salt's water reducer and cement-based material have good adaptability it is ensured that fresh paste upper flow regime, And have longer operable time.
2nd, the interpolation of organic silicon defoamer can effectively eliminate the deleterious bubbles introducing during slurry stirring.
3rd, the extender compounding both can compensate well for early-age shrinkage, the receipts producing after again can making up slurry hardening well Contracting.Compounding extender introduces alunite [aluminum potassium sulfate kal (so in this non-fragment orbit lifting proprietary material4)2], sulphuric acid sub- Ferrum feso4, ferric chloride (fecl3) etc. composition, with hydrolysis product of cement react formation entringite (c3a·3caso4·32h2O, Fluorine lithium chromic salts [c3a·caso4·14h2O], nitrous acid calcium aluminate [c3a·ca(no2)2·11h2O], calcium chloroaluminate [c3a· cacl2·10h2O], chlorine calcium silicates [3cao sio2·cacl2·12h2O], oxychlorination calcium [cacl2·3ca(oh)2· 12h2O], [cacl2·ca(oh)2·h2O], and Tuo Bomolai stone [3ca0 2sio2·4h2O] etc. crystal.Plasticity slurry is subject to Crystallographic expansion stress, on the one hand compensate for contraction and eliminates crackle making Behavior of Hardened Cement Paste more they tend to densification again.
4th, the quartz sand optimizing particle size range makes slurry can obtain preferable mobility, can obtain higher-strength again.
5th, slag micropowder and floating bead itself have preferable volcanic ash row, and the interpolation of their appropriate interpolation was both participated in Active reaction, improves hydration and hardening microenvironment and pore size distribution$, the long-term strength to placing body and the durability of placing body again There is huge improvement.
