Problems solved by technology

The strength and water resistance of concrete currently on the market are not very ideal, and the durability is poor, which cannot meet the high requirements of people. When used as the main material for electric pole production, it is easy to cause damage in special environments. Growing demand for high-performance concrete poles resistant to freeze-thaw and chloride ion penetration

Embodiment Construction

[0016] see figure 1 , the present invention provides a technical solution:

[0017] A high-performance concrete pole with anti-freeze-thaw and anti-chloride ion penetration, including cement, fly ash, mineral powder, fine aggregate, coarse aggregate, water, polypropylene mesh fiber and air-entraining water reducer, It is characterized in that: the dosage of the cement is 280Kg / m 3 , the amount of the fly ash is 50Kg / m 3 , the amount of mineral powder is 60Kg / m 3 , can significantly reduce the effect of heat of hydration, improve the stability of the coagulation degree, and use mineral powder and fly ash together, which can effectively reduce the high cost caused by the single mixing of mineral powder. Using mineral powder and powder Coal ash is mixed and used at the same time, which can maintain the strength of the concrete to the maximum effect, improve the performance of the concrete and ensure the production cost of the concrete at the same time. The dosage of the fine a...

Abstract

The invention relates to the technical field of concrete electric poles, and in particular relates to a high-performance concrete electric pole with resistance to freeze thawing and chloride ion penetration. The concrete electric pole includes the following components: 280 kg/m<3> of cement, 50 kg/m<3> of fly ash, 60 kg/m<3> of mineral powder, 632 kg/m<3> of fine aggregate, 1174 kg/m<3> of coarseaggregate, 164 kg/m<3> of water, 1.5 kg/m<3> of polypropylene mesh fibers and an air-entraining water reducing agent. Through optimization of aggregate gradation, control of a sand rate and a water-cement ratio, and addition of the ultrafine-fiber polypropylene mesh fibers, the bonding performance of fine sand and other ingredients is improved, the problems of reduced strength, impermeability, durability, crack resistance and workability when concrete is prepared from superfine sand are effectively solved, and the engineering construction costs are greatly reduced; and at the same time, the air-entraining water-reducing agent is added, so that the impermeability and freeze-thawing resistance of the concrete are improved.

Description

technical field [0001] The invention relates to the technical field of concrete electric poles, in particular to a high-performance concrete electric pole with resistance to freeze-thaw and chloride ion penetration. Background technique [0002] Electric poles are made of concrete as the main raw material and steel bars. Concrete generally refers to cement as the main cementitious material, mixed with water, sand, stones, and chemical admixtures and mineral admixtures if necessary, in an appropriate proportion. The artificial stone is made by uniform mixing, dense molding and curing hardening. As a building material with a large amount and a wide range of use in the world, concrete has been widely developed in various countries and regions for its good mechanical properties, economy and adaptability to the environment. put forward higher requirements. As the most commonly used structural form in the field of civil engineering, concrete structures have extremely complex con...
