Concrete formula of lightweight thin-wall telegraph pole

Abstract

The invention relates to the technical field of concrete, and in particular discloses a concrete formula for a portable thin-walled utility pole. The concrete formula for a portable thin-walled utility pole is made of the following raw materials in parts by weight: rapid hardening sulfoaluminate cement 500 ~600 parts, 30~40 parts of gravel, 100~110 parts of mineral powder, 15~20 parts of sodium silicate glass, 40~50 parts of reinforcing agent, 400~430 parts of phosphorus slag powder, 40~50 parts of white mud fiber, activator 20-30 parts, 20-30 parts of water reducing agent, 300-320 parts of water. The present invention overcomes the deficiencies of the prior art, and rationally mixes fast-hardening sulfoaluminate cement, gravel, mineral powder, sodium silicate, reinforcing agent, phosphorus slag powder, white mud fiber, activator, water reducer and water Compared with the high-strength concrete formula, it lays the foundation for the manufacture of thin-walled utility poles, thereby achieving the purpose of reducing the weight of utility poles, and has a wide range of applications.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a portable concrete formula for thin-walled utility poles. Background technique [0002] Telephone poles, as the name suggests, are poles for wires. Appearing in various villages-fields-roads-streets, it was one of the important infrastructures in early China. All kinds of electric poles in the early days started from wooden poles, even including high-voltage electric poles whose voltage level was not too high. Later, due to the development of steel and reinforced concrete, and technical requirements, these two materials replaced most of the wooden poles, and the applicable wood was gradually scarce, and it was basically difficult to see wooden poles in the city. However, in some less developed places, wooden poles are still used to erect telephone lines, because wooden poles are light in weight and easy to erect, and the load-bearing and tensile force of telephone lines are s...

Problems solved by technology

[0003] Among them, the wall of the existing steel bar and concrete is thick and heavy, which brings many difficulties to construction, transportation, operation and maintenance. Therefore, it is necessary to develop a high-strength concrete to reduce the thickness of the wall of the utility pole.
