Abstract

The invention discloses a method for processing cement pipe piles by utilizing carbon fiber and recycled concrete. Firstly, recycled concrete is prepared, waste concrete is crushed, and the crushed waste concrete is passed through a 38 μm sieve to obtain waste concrete powder; zeolite powder is Mix it with waste concrete powder, and put it into a ball mill for ball milling to obtain the first mixed powder. The ball milling time is 2 hours; then add the first mixed powder into the sodium hydroxide solution, and heat it under the condition of 30°C for 1 day, filtered with a 200-mesh sieve to obtain the second mixed powder; the sodium hydroxide solution had a concentration of 1mol / L. The present invention provides a method for processing cement pipe piles using carbon fiber and recycled concrete, controlling the reasonable proportion of components, so that the mechanical properties of the prepared cement pipe piles are better, and at the same time using waste concrete as the base material for preparation, saving The cost has a high economic effect.

Description

technical field [0001] The invention relates to the field of pipe pile manufacturing, in particular to a method for processing cement pipe piles by using carbon fiber and recycled concrete. Background technique [0002] Pipe piles are divided into post-tensioned prestressed pipe piles and pretensioned prestressed pipe piles, prestressed concrete pipe piles (PC pipe piles), prestressed concrete thin-walled pipe piles (PTC pipe piles) and high-strength prestressed pipe piles Stressed concrete pipe piles (PHC pipe piles) are mostly used in the market today to prepare concrete and manufacture pipe piles. [0003] Cement is used to prepare concrete and concrete for a wide variety of applications including, but not limited to, roads, parking lots, bridges, walkways, and support structures. With the acceleration of urbanization in our country, the advancement of science and technology, the construction industry has entered a stage of rapid development, and the accompanying constru...
