Compared with prior art, the beneficial effects of the present invention are:
Devised in the present invention it is a kind of using carbon fiber and regeneration concrete processing cement pipe pile method, wherein by pair
Discarded concrete carries out secondary use, regeneration concrete is prepared, then by processing to regeneration concrete, obtain cement
Composition not only increases the mechanical property of cement pipe pile, reduces simultaneously for serving as the base material for preparing cement pipe pile
Cost has high economic benefit, effectively practical；By being processed to carbon fiber and cellulose fibre in the present invention, obtain
To fiber composition, fiber composition is easily separated into fibre single thread under the action of the immersion of water and blender frictional force, from
And effect of prestressed is played, the mechanical property of cement pipe pile can be effectively improved, the freeze-thaw resistance and impermeability of cement pipe pile are enhanced.
When the present invention prepares regeneration concrete, it is added to zeolite powder, the per unit pore volume in material can be effectively reduced, is sticked
Regeneration concrete micro-crack produced during the preparation process is closed or repaired, the bond strength between each component is enhanced, and keeps regeneration mixed
Solidifying Soil Interface plot structure tends to be fine and close, compactness when improving cement pipe pile preparation between each component.
The present invention is calcined twice when preparing regeneration concrete, while being carried out before calcination to the first mixed powder
Hydro-thermal provides alkaline environment by sodium hydroxide solution for subsequent synthetic reaction, can sufficiently activate in this way to flyash,
Improve the aggregate velocity of regeneration concrete.
In the present invention in the secondary use to discarded concrete, by carrying out crushing, stirring to discarded concrete, and add
Enter various auxiliary materials and regeneration concrete is made, wherein the proportion of discarded concrete is reduced with the increase that steel slag matches, regenerates coagulation
The intensity of soil can be presented one and first increase the trend reduced afterwards, and when the mass percent of steel slag is 0.8%, intensity reaches highest
Value continues growing steel slag proportion, and intensity declines instead, so the mass percent of steel slag is selected as 0.8% in the present invention；Addition
Steel slag, can provocative reaction when whole system alkalinity, to make whole system there are a most suitable hydrated products in aquation
The alkalinity ranges of generation improve the generation of hydrated product.
It also added desulfurized gypsum in the present invention, the intensity of regeneration concrete can be improved.Steel slag can excite in the present invention
System alkalinity, slag powders are under the excitation of alkali, and the limestone surfaces in discarded concrete generate a large amount of entringite and C-S-H is solidifying
Discarded concrete particle is closely joined together and is formed spacial framework by glue, what the subsequent continuous aquation of slag powders generated
C-S-H gel and entringite are constantly filled in the hole of network, final to wrap up discarded concrete particle and cause slurry more
It is close, the intensity of regeneration concrete is improved, to improve the intensity of the cement pipe pile prepared using regeneration concrete as raw material.
After preparing regeneration concrete in the present invention, each component is added, cement composition is made again, cement pipe pile can be reduced
Chloride ion permeability, increasing flexural strength and module strength, the addition of sucrose reduces cementing needed for preparation process
The amount of material, reduces costs, while improving the wearability of cement pipe pile, reduces shrinking percentage.
When preparing cement composition in the present invention, it is added to flyash, can not only cooperate with silicon ash and realize " double-doped " effect
Fruit, while flyash can also be cooperated with the zeolite powder in regeneration concrete, between each component for improving cement composition
It is compatible；Aluminium hydroxide is added when being calcined three times, the alkaline environment phase interworking in aluminium hydroxide, flyash and regeneration concrete
It closes, not only increases the whole activation degree of flyash, while zeolite can also be generated when calcining three times, it is further to improve
The compactness of regeneration concrete improves the interfacial structure of regeneration concrete, and when preparing cement composition, it is mixed that regeneration can be improved
Degree of cohering between solidifying soil and other components.
When preparing fiber composition in the present invention, pearl filler excessively will affect the formation of gel, we select to control
The amount of pearl filler accelerates the formation of gel, this is also convenient for cement pipe pile can preferably mix between each component in the preparation
It closes, reduces the amount of colloid, save the cost.
Water-reducing agent selects polycarboxylic acid series high efficiency water reducing agent or naphthalene water reducer, cement composition in the present invention in the present invention
In be added to silicon ash, " double-doped " effect is reached by high-efficiency water-reducing agent of poly-carboxylic acid and silicon ash, while in cement admixture preparation
It is added to flyash, the Pore Solution for fitting through dilution effect, chemical effect, reducing when material mixing of flyash and silicon ash
PH；In the next steps, after material is mixed and semi-finished product tubular pole is prepared, present invention employs normal pressure steamings
Vapour maintenance, with the raising of curing temperature, the quickening of hydrated reaction of cement speed, the speed that the basicity in concrete reduces adds
Fastly；
Simultaneously because the cooperation of high-efficiency water-reducing agent of poly-carboxylic acid and silicon ash, the cooperation of flyash and slag powders, when prepared by tubular pole
Mixed material when being stirred, each component therein quickly dissolves, and quickly improves the basicity in mixed material, simultaneously
The hydration temperature of mixed material is also improved, the speed of hydration reaction is accelerated, increases the generation quantity of hydrated product, is improved
The demoulding strength of cement pipe pile.
The method that directly molding perfusion is used in the present invention, concrete are directly filled into the inner cavity of mold, avoid the occurrence of
The phenomenon that concrete particle is fallen reduces human cost, saves labour；Upper mold, lower mold are tightened when molding simultaneously, is kept away
Exempt from the problem of concrete tubular pile joint close spillage occur, ensure that the quality of concrete tubular pile.
A kind of method using carbon fiber and regeneration concrete processing cement pipe pile is provided in the present invention, control is reasonable
Component is matched, so that the mechanical property of the cement pipe pile of preparation is more preferable, entire cement is reduced by the preparation of cement composition
The chloride permeability rate of tubular pole, while being prepared using discarded concrete as base material, cost is saved, it is with higher
Economic benefits.
