The design that concrete is anticorrosion structure at special Working environment because of the destruction subject matter that causes of corrosion can not meet and causes.Such as flue gas at a high speed washes away district, or the bridge spanning the sea engineering of the wave is high wind disease, except requiring anticorrosion also to have resistance to abrasion; Certain deformation that vibration in gas or liquid-flow process, warm sex change and wind-force cause, requires concrete structure to keep preservative property under the prerequisite having in high tenacity; Anticorrosion structure has the requirement of oneself to the intensity of matrix, such as glass flake, if sex change has occurred matrix, glass flake must ftracture so, and this just requires anticorrosion structure will in the situation that being out of shape with matrix, still will keep antiseptic property.
Glass flake: in the form of sheets, energy acid-and base-resisting and saline solution corrosion, have very strong permeability resistance to acid-alkali salt and water vapor, and then greatly strengthen the work-ing life of matrix.
In order to guarantee the high-strength and high-durability of high performance concrete, when configuration high performance concrete, answer one or more active mineral admixtures of admixture, as flyash, slag, silicon ash etc.The Main Function of active mineral admixture in concrete comprises filling effect and active effect.High performance concrete improves concrete density and impermeability by reducing water-cement ratio on the one hand, and fly ash is one of important measures that reduce water consumption, and flyash and ground blast furnace slag have " super folded effect " aspect water-reducing effect; Due to the micro-packing effect of mineral admixture, make the size distribution in concrete more rational on the other hand, concrete is finer and close, and the active effect of mineral admixture makes again concrete intensity be guaranteed.A large amount of research data and engineering practices show, in concrete, mix in a large number appropriate flyash, slag, silicon ash isoreactivity mineral admixture, can greatly improve the performances such as concrete impermeability, frost resistance, alkali resistant aggregate reaction ability and anti-harmful ion infiltration.
Commonly use and refer to as the flyash of concrete adulterant the dust of collecting from the flue of coal-fired station's coal-powder boiler, according to factors such as fineness, water demand ratios, be divided into I level, II level, III level, standard is shown in the flyash > > (GB1596-91) of < < for cement and concrete.The breeze of making cement admixture refers to pulverizes by the slag of blast furnace ironmaking the powder obtaining; there is activity; be divided into S75 level, S95 level, S105 level, standard is shown in the GBFS > > (GB/T 18046-2008) of < < for cement and concrete.The present invention selects I level flyash and S95 level breeze as composite active mineral admixture.
Adopting low water binder ratio is to guarantee concrete intensity, is also the key that improves concrete durability.The present invention's water reducer used is high-efficiency water-reducing agent of poly-carboxylic acid, and its solid content is 22%～24%, and water-reducing rate is 28%～32%.
During higher grade of preparation strength high-strength concrete, should first select non-research work of air entrained type high efficiency water reducing agent.High efficiency water reducing agent can be divided into naphthalene system, polycarboxylic acid series, sulfamate system and melamine series at present.The gelling material such as use of the present invention and cement have the high-efficiency water-reducing agent of poly-carboxylic acid of better consistency, reduce water consumption, have both guaranteed that concrete mix had good workability, improve again concrete strength, reduce shrinkage and creep.The present invention uses polycarboxylic acid series additive, and cohesiveness is little, and in mix, the parcel of slurry and stone is good, and stone is evenly distributed in slurry, not stratified, do not emanate, for liquid.
The consumption S/ (the consumption S+ stone consumption G of sand) × 100% of sand coarse aggregate ratio=sand is mass ratio.The variation of sand coarse aggregate ratio, can make the total surface area of aggregate (playing the granular loose material of skeleton or filling effect in concrete) have remarkable change, thereby the workability of concrete mix is had to considerable influence.The general principle of determining sand coarse aggregate ratio is: guaranteeing under the prerequisite of cohesiveness that concrete mix has and mobility the optimum sand coarse aggregate ratio in the timesaving of grout.
Compared with prior art, the invention has the beneficial effects as follows:
1, add anticorrosion antiwear composition, difficulty of construction is little, with low cost, favorable anti-corrosion effect, wear resisting property are good, external force, internal stress destruction be can effectively prevent and sour acid liquid corrosion or sweep of gases resisted, and use and keep in repair also very convenient, can effectively solve and extend matrix work-ing life, can reduce to a great extent maintenance cost.
2, by adopting ordinary Portland cement+high efficiency water reducing agent+composite active mineral admixture preparation high performance concrete; the starting material of economical rationality have been used; and find breeze and flyash suitable volume and the optimum mix amount in high performance concrete; guarantee concrete economy, simultaneously concrete workability, mechanical property, endurance quality excellence.
