Problems solved by technology

Since this kind of pole and tower structure is a metal structure, it is prone to corrosion, so the service life is short and the maintenance workload is heavy.
However, the mechanical strength of traditional ordinary concrete poles is not high, so it is difficult to apply to high-voltage power transmission lines, unless the cross-section is made relatively large, but this not only increases the self-weight, but also makes the construction very difficult. More importantly, it also increases cost

Description

[0001] technical field [0002] The invention belongs to the technical field of concrete, and more specifically relates to a concrete used for preparing electric poles. [0003] Background technique [0004] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. Concrete refers to a mixture made of cement (organic, inorganic or organic-inorganic composite), granular aggregates, water, chemical admixtures and mineral admixtures that need to be added in appropriate proportions, or After hardening, it forms a composite material with an accumulation structure (usually cementitious material, water, ...
