Abstract

The invention discloses a kind of red mud sills for roadbed steady layer of water, by following components component according to parts by weight than constituting: red mud 25-30, white lime 7-8, flyash 7-8, slag 8-10, metasilicate pentahydrate sodium 5-6, cement 1-2, graded broken stone 70-80.The present invention can efficiently use red mud, and actually detected after construction, and anti-seismic performance, antistrip performance and intensity are slightly above existing level, but its cement consumption is relatively low, each component purchase cost is also relatively low, therefore overall cost is relatively low, can satisfy existing construction reference.

Description

A kind of red mud sill for roadbed steady layer of water
Technical field
The present invention relates to a kind of construction materials, more particularly to a kind of red mud sill for roadbed steady layer of water.
Background technique
Roadbed is the basis on track or road surface, is the earthen structure by excavating or filling and formed.The master of roadbed Act on be for track or road surfacing and train or driving operation necessary condition is provided, and bear track and rolling stock or The dead load and dynamic load of person road surface and traffic loading, while load being transmitted and being spread to ground depths.On vertical section, road Base must assure that the elevation that route needs;In the plane, roadbed connect the route that composition completely penetrates through with bridge, tunnel.
Steady layer of water is the abbreviation of cement stabilized macadam layer, i.e., consolidates graded broken stone using cement, by compacting, has been conserved At.
And the steady layer of water of roadbed not only wants stabilization gravel layer, it is also necessary to bear, transmit dead load and dynamic load, therefore its for Anti-flaking energy, toughness, intensity etc. have higher requirements.Mainly stablized at present using high-performance cement as adhesive production water Layer, while adding different additives and being adjusted, although it has preferable effect really, cost is also higher.
Mud is that aluminium industry extracts the pollution waste residue being discharged when aluminium oxide, and average 1 ton of aluminium oxide of every production is subsidiary Generate 1.0~2.0 tons of red muds.China is used as big alumina producing state of the world the 4th, and the red mud discharged every year is up to millions of tons, This can cause environment greatly to destroy.
Therefore, a kind of red mud sill for roadbed steady layer of water of applicant, performance are not less than currently used high property Energy cement, but its cost is relatively low, additionally it is possible to solve the problems, such as current red mud pollution.
Summary of the invention
In view of the above drawbacks of the prior art, technical problem to be solved by the invention is to provide one kind to be used for subgrade drainage The red mud sill of steady layer.
To achieve the above object, the present invention provides a kind of red mud sills for roadbed steady layer of water, by following components Component is according to parts by weight than constituting: red mud 25-30, white lime 7-8, flyash 7-8, slag 8-10, metasilicate pentahydrate sodium 5- 6, cement 1-2, graded broken stone 70-80.
The red mud is combination method red mud;
The slag is the slag generated after making steel;
The cement is road silicate cement;
Graded broken stone is grouped as by the group of following weight fraction ratio: 20mm~30mm rubble 10-15,10mm~20mm rubble 30- 40,5mm~10mm rubble 50-60,0~5mm aggregate chips 10-15;
The red mud, white lime, flyash, slag, are dry powder, and fineness requirement is as follows: D50 >=0.1 ㎜, D75 >= The ㎜ of 0.07 ㎜, D25 >=0.15.
In use, first taking out each component according to corresponding proportion, be then placed into blender, be subsequently poured into always Body weight (weight of entire solid) than be 1-1.3 water is stirred uniformly, then poured, natural coagulation, maintenance i.e. It can.
The beneficial effects of the present invention are: the present invention can efficiently use red mud, and actually detected, the antidetonation after construction Performance, antistrip performance and intensity are slightly above existing level, but its cement consumption is relatively low, and each component purchase cost is also inclined It is low, therefore overall cost is relatively low, can satisfy existing construction reference.
