Abstract

The invention discloses an admixture special for high-performance conductive concrete and a preparation method for the admixture. The admixture is prepared from the following raw materials, by mass, 100-165 parts of fly ash, 50-100 parts of mineral powder, 10-30 parts of copper fibers, 1-15 parts of polyphenylacetylene and 1-15 parts of polyvinylpyrrolidone. The admixture special for the high-performance conductive concrete is prepared by mixing the raw materials and is used for the cement concrete; and the admixture can exert the multi-component composition effect, the frost resistance, the permeability resistance and the electrical conductivity of the concrete can be improved, the hydration heat of the concrete can be reduced, and a high-quality concrete raw material can be provided forurban buildings and structures.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a special admixture for high-performance conductive concrete and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy and the continuous acceleration of construction projects, the application of various functional concrete is becoming more and more extensive. As a functional concrete, conductive concrete has a wide range of applications in roads, bridges and buildings. Prospects are mainly manifested in the following three aspects: [0003] (1) Electromagnetic shielding: Due to the rapid development of the electronics industry and communication infrastructure, electronic products such as mobile phones and computers are very common in daily production activities. Electronic products will release electromagnetic waves during use, which will cause certain harm to the human body. At the same time, electr...
