Carbon-silicon reinforced concrete tubular pile and production method thereof

Abstract

The present invention discloses a carbon-silicon reinforced concrete tubular pile; since ethoxylated rubber fiber is doped, inner pore structure of concrete can be effectively improved and mass closed pores can be formed so as to prevent capillary pores from forming a continuous through meshed structural system, an 'anti-carbonization belt' is formed, inhibition on carbon dioxide invasion is further enhanced, and it is also additionally possible to reduce harmful pores and defects in the concrete structure, reduce alkality of hydrates and promote the conversion of low-strength hydrates to high-strength hydrates.

Description

technical field [0001] The invention relates to a carbon-silicon-reinforced concrete pipe pile, in particular to a carbon-silicon-reinforced concrete pipe pile and a preparation method thereof. Background technique [0002] Concrete structure is one of the most widely used structures. About 70% of the house construction and 50% of bridge structures in China use concrete structures. With the increase of the service time of these engineering structures, the durability damage of concrete materials and structures is becoming more and more serious. The more attention is paid, many engineering structures often cause functional degradation or even structural damage due to durability, which brings unnecessary losses to society. Concrete carbonation is one of the important durability indicators of concrete. Due to carbon dioxide in the atmosphere and concrete The reaction of alkaline substances in the concrete makes the concrete appear neutral, which is called the carbonization of co...

[0002] Concrete structure is one of the most widely used structures. About 70% of the housing construction and 50% of bridge structures in China use concrete structures. With the increase of the service time of these engineering structures, the durability damage of concrete materials and structures is becoming more and more serious. The more attention is paid, many engineering structures often cause functional degradation or even structural damage due to durability, which brings unnecessary losses to society. Concrete carbonation is one of the important durability indicators of concrete. Due to carbon dioxide in the atmosphere and concrete The reaction of the alkaline substances in the concrete makes the concrete appear neutral, which is called the carbonization of the concrete. Carbonization makes the steel bars in the concrete structure lose the protection of the passivation film, which easily makes the steel bars rust, and then destroys the structure. With the continuous advancement of the industrialization process, the emission of carbon dioxide has increased greatly, which has a negative impact on the durability of concrete structures while producing the greenhouse effect;
