Description
Technical field
The present invention relates to construction of railways technical field, specifically one kind kind have high fluidity, clearance through and
The template self-compacting concretes of CRTS III of education resistance.
Background technology
The plate-type non-fragment orbits of CRTS III are that, by a kind of new-type non-fragment orbit of China's independent research, it is different from CRTS I
Type and the type non-fragment orbits of CRTS II, it is not necessary to using cement emulsified asphalt mortar as packed layer, but use have it is good and
Yi Xing, mechanics insensitive to environment temperature and excellent and the self-compacting concrete of durability.It is used for packed layer at this stage
Self-compacting concrete have that following some is not enough：1st, the workability of concrete mix is poor, bleeding, bleeding etc. easily occurs existing
As.The mobility and J rings of reinforcement mixture simply have ignored the stability of whole concrete mix bubble layer by property,
Cause mixture out of order, the defect phenomenons such as bubble layer, laitance occurs in packed layer after filling plate.2nd, loss of slump and divergence
Loss is larger, is unfavorable for site operation.3rd, there is shrinkage phenomenon in the self-compacting concrete after being molded, causes packed layer and track plates
Between there is gap phenomenon.
The content of the invention
In order to avoid the weak point that prior art is present, the present invention provides a kind of with high fluidity, clearance through
With the template self-compacting concretes of CRTS III of education resistance.
The present invention solves technical problem and adopts the following technical scheme that：
A kind of template self-compacting concretes of CRTS III with high fluidity, clearance through and education resistance, it is characterised in that
The concrete includes Binder Materials, sand, rubble, water, the concrete gel material consumption≤580kg/m3；The concrete
Water consumption≤180kg/m3；The concrete sand ratio is 52%-54%.
Further, by weight, the concrete gel material component is as follows：
Cement 285-295 parts,
Flyash 170-175 parts,
Swelling agent 45-52 parts,
It is viscous to change material 22-30 parts,
Water 150-195 parts,
Water reducer 4-8 parts.
Further, by weight, the concrete gel material component is as follows：
292 parts of cement,
173 parts of flyash,
48 parts of swelling agent,
It is viscous to change 27 parts of material,
178 parts of water,
6 parts of water reducer.
Further, the rubble is mixed using two kinds of grades of 5-10mm and 10-16mm and matched somebody with somebody；Grade 5-10mm rubbles account for 40%, grain
Level 10-16mm rubbles account for 60%.
Compared with the prior art, the present invention has the beneficial effect that：
Due to being furnished with bar-mat reinforcement under packed layer narrow space, and plate under the templates of CRTS III, irrigated using other self-compacting concretes
It is difficult to fill closely knit.Therefore packed layer self-compacting concrete must have good service behaviour, physical property and endurance quality.
Self-compacting concrete of the present invention selects suitable sand coarse aggregate ratio, grading of aggregates and Binder Materials, allows coarse aggregate to be suspended in viscous enough
In the mortar of degree and deformability, under self gravitation effect, mortar wraps up coarse aggregate flow forward together, by between reinforcing bar
Gap, forms uniform compact structure.High performance expansion admixture is selected simultaneously, the expansion rate of concrete is ensured, makes it tight with track plates
It is closely connected to be combined.
Specific embodiment
Explanation is further explained to technical solution of the present invention below by way of specific embodiment.
