Concrete pipe pile and preparation method thereof
The invention discloses a concrete pipe pile which is prepared from the following raw materials in parts by weight: 500-640 parts of common silicate cement, 300-400 parts of yellow sand, 200-300 parts of gravels, 14-20 parts of aluminum phosphate, 7-15 parts of a poly carboxylic acid water reducing agent, 16-20 parts of polyethylene wax, 0.1-0.2 part of dibenzoyl peroxide, 5-6 parts of maleic anhydride, 2-3 parts of methoxy polyethylene glycol, 4-7 parts of ethyecellulose, 0.7-2 parts of sp-80, 50-70 parts of waste rubber powder and 0.1-0.2 part of triethylamine. According to the concrete pipe pile disclosed by the invention, by doping the ethoxylated rubber fiber, the inner pore structure of the concrete can be effectively improved to form a lot of closed pores to prevent pores from forming a continuous penetrating netty structure system so as to play a role of further enhancing inhibition of invasion of carbon dioxide. In addition, the content of harmful pores and defects in the concrete structure can be further reduced, the alkalinity of hydration products is reduced, and the low-strength hydration products are promoted to be converted into high-strength hydration products.
