Abstract
The invention discloses a PHC pile cement as well as a manufacturing method thereof, comprising: clinker: 35 to 90 wt.%, mineral powder: 0 to 60 wt.%, fly ash: 0 to 20 wt.%, and functional blended materials: 5 to 20 wt.%. The PHC pile cement produced by the cement and the manufacturing method of the invention has a high compressive strength of over 60MPa by a standard maintenance period of 28 days; and the steam curing strength of concrete is high due to the exemption of high-pressure steam curing under laboratory conditions, and the strength can reach above C80 three days after the steam curing demolding, and the cement is applied to the PHC pile production.
Description
Technical field
The present invention relates to a kind of tubular pile cement and manufacture method thereof, more particularly relate to a kind of PHC tubular pile cement and manufacture method thereof that does not need high-pressure steaming and cultivating.
Background technology
It is PTC that pile tube is divided into prestressed concrete pipe pile (code name PC), prestressed high-strength concrete pile (code name PHC) and thin-wall pipe pile code name by strength grade of concrete and wall thickness.The concrete strength of PC stake must not be lower than C50, and PTC stake strength grade must not be lower than C60, and the strength grade of concrete of PHC stake must not be lower than C80.Atmospheric steam curing is generally adopted in PC stake and PTC stake, generally will be through the injection of 28 days ability.And the PHC stake, it is steam-cured to enter autoclave after the demoulding, the steam press maintenance through about 10 normal atmosphere, 180 degree, and strength grade of concrete reaches C80, only needs three, four days from shortest time of being molded into use.Prestressed high-strength concrete pile, prestressed concrete pipe pile are applicable to the embedded footing on piles, low capped pile foundation plinth of industry and covil construction.The basic design of engineerings such as railway, highway and bridge, harbour, water conservancy, municipal administration, structures also can be with reference to use.Will obtain the PHC pile tube at present must be through common steam-cured and high-pressure steaming and cultivating twice technology, energy consumption height not only, and the cost height, danger is also high, and production capacity is low, PHC pile tube that more can't production overlength super large.
Summary of the invention
One of purpose of the present invention provides a kind of PHC tubular pile cement and manufacture method thereof that does not need high-pressure steaming and cultivating.
This and other purpose of the present invention will and be described by following detailed description and further launch and set forth.
PHC tubular pile cement of the present invention, form by following:
Grog 35～90 weight %, breeze 0～60 weight %,
Flyash 0～20 weight %, functional admixture 5～20 weight %.
Further, PHC tubular pile cement of the present invention, form by following:
Grog 37～90 weight %, breeze 10～45 weight %,
Flyash 1～10 weight %, functional admixture 10～20 weight %.
PHC tubular pile cement of the present invention does not in use need high-pressure steaming and cultivating.
In PHC tubular pile cement of the present invention, 15～18% of described finished cement grain composition＜3um, 82～88% of＜32um, cement normal consistency water consumption≤27.6%, presetting period≤150min, final setting time≤200min, three days ultimate compression strength 〉=28MPa, 28 sky ultimate compression strength 〉=59MPa, the steam-cured intensity 〉=60MPa of cement mortar.
In PHC tubular pile cement of the present invention, described grog is a Portland clinker, the specific surface area 400～600m of described breeze
2/ kg, (concrete breeze rank 〉=S95).Meet more than the S95 rank of GB/T18046 regulation.Flyash meets the technical requirements of the cement active mixed material of GB/T1596 regulation with flyash.Described functional admixture is the mixture of anhydrite and industrial residue micro mist, has performances such as early strong, microdilatancy, and the weight ratio of the two is 1～100: 100～1, and what can select is 10～90: 90～10, be preferably 25～80: 75～20.Described industrial residue micro mist is iron-tion slag, aluminium manufacturer's red mud or cement flue Dust, and activated silica content is 8～50%.In the manufacture method of PHC tubular pile cement of the present invention, adopt cement and breeze respective grinding process.28 days ultimate compression strength height during the PHC tubular pile cement normal curing of producing with cement of the present invention and manufacture method can reach more than the 60MPa; Under testing laboratory's condition, remove high-pressure steaming and cultivating from, concrete steam-cured intensity height, 3 days intensity reaches more than the C80 after the steam-cured demoulding, is suitable for the production of PHC pile tube.As gelling material,, directly cancel high-pressure steaming and cultivating technology by single variety cement by the optimization of aggregate and steam curing system, and still can satisfy the production of PHC pile tube, and both saved the energy, increased production capacity again, reduce or eliminate potential safety hazard, and can production overlength ultra-large type pile tube; Concerning newly-built enterprise, can reduce facility investment, reduce floor space, can be described as the revolution of pile tube industry.
In the present invention, admixture functional admixture, make to exempt to press and steam the PHC tubular pile cement and have these excellent performances.Functional admixture has improved the adaptability of cement, and application property improves concrete degree of compactness, improved intensity, had a synergistic effect, improved the conventional intensity and the steam-cured intensity of cement with slag powders is compound, certain microdilatancy performance has improved the corrosion-resistant property of cement.
In the present invention, adopt grain composition method control cement performance, help improving the rheological of cement and the density of cement stone submicroscopic(al) structure, in exempting to press the experimental study of steaming the PHC tubular pile cement, tentatively set up the relation of performances such as cement granules distribution and strength of cement, bleeding, hydration heat, improved the production quality control level.
The all raw material of Shi Yonging etc. all is conventional uses in the present invention, can buy from market.In the present invention, refer in particular to as non-, all amount, per-cents are weight unit.
Below in conjunction with embodiment the present invention is carried out concrete description.As known by the technical knowledge, the present invention can realize by other the embodiment that does not break away from its spirit or essential feature.Therefore, following embodiment with regard to each side, all just illustrates, and is not only.All within the scope of the present invention or the change that is equal in the scope of the present invention all be included in the invention.
