Abstract

The invention discloses a concrete composite tube, and belongs to the field of composite tubes. The concrete composite tube comprises a glass steel tube and a concrete layer with which the glass steeltube is sleeved, wherein the concrete layer is prepared from water, sand, cement and a water reducing agent, and the ratio of the sand to the cement to the water reducing agent is 2380:1040:(27-30).According to the concrete composite tube, the proportion of the ingredients of the concrete layer is reasonable, the peaceability of the concrete layer is enhanced, the adhesion degree of the concretelayer and the glass steel tube is high, and the concrete composite tube is not prone to disengagement.

Description

technical field [0001] The invention relates to the field of composite pipes, in particular to a concrete composite pipe. Background technique [0002] The outer layer of the concrete composite pipe is a concrete layer, and the inner layer is a glass steel pipe; the concrete composite pipe has the advantages of good corrosion resistance and long service life, and has been widely used in many fields such as sewage pipes and river comprehensive treatment. [0003] However, the concrete layer of the existing concrete composite pipe is easy to fall off due to unreasonable formula and weak adhesion with the glass steel pipe. Contents of the invention [0004] In order to solve the above problems, the present invention provides a concrete composite pipe, the composition ratio of the concrete layer is reasonable, the workability of the concrete layer is enhanced, the adhesion between the concrete layer and the glass steel pipe is strong, and it is not easy to fall off. [0005] ...
