Description
Technical field
The present invention relates to a kind of anti-carbonated concrete pile tube, particularly relate to a kind of anti-carbonated concrete pile tube and preparation method thereof.
Background technology
Concrete structure is one of structure be most widely used, the have an appointment building construction of 70% and the bridge structure of 50% of China have employed concrete structure. along with the growth of these engineering structures duration of service, the durability damage of concrete material and structure more and more comes into one's own, many engineering structures are often because the reason of weather resistance causes using function to degenerate even structure deteriorate, unnecessary loss is brought to society. concrete carbonization is one of important durability index of concrete, due to the carbonic acid gas in air and the alkali substance reaction in concrete, namely the process making concrete present neutralisation is called concrete carbonization, carbonization makes the reinforcing bar in concrete structure lose the protection of passive film, reinforcing bar is very easily made to get rusty, and then structure is destroyed. along with the continuous propelling of process of industrialization, the quantity discharged of carbonic acid gas increases, while generation Greenhouse effect, also disadvantageous effect is created to the weather resistance of concrete structure,
The present invention wants to adopt waste and old rubber powder as modified filler, reduce concrete carbonization, but first rubber particle surface is nonpolar, cement matrix is polarity, both consistencies are poor, under surface tension effects, cement slurry is subject to the tension force deviating from rubber particle surface, rubber and grout bonding surface is made to produce crack, this crack makes concrete density reduce, and provides passage more easily also to the intrusion of carbonic acid gas simultaneously, enhances carbonization effect on the contrary, therefore to reduce carbonization, first will carry out modification to rubber surface.
