Mass conductive concrete based on ironmaking dedusting ash

Abstract

The invention discloses mass conductive concrete based on ironmaking dedusting ash. The mass conductive concrete is prepared from components in parts by mass as follows: 100 parts of cement, 1-100 parts of fly ash, 1-80 parts of blast furnace slag powder, 1-25 parts of the ironmaking dedusting ash, 120-240 parts of yellow sand, 10-20 parts of blast furnace slag iron particles, 0-360 parts of gravel with the particle size of 5-25 mm, 4-10 parts of a water reducer, 10-25 parts of copper fiber, 1-15 parts of polyphenylacetylene, 1-15 parts of polyvinylpyrrolidone and 3-100 parts of water. The concrete has good anti-penetrability performance, anti-freezing performance, low hydration heat and conductive performance, the conducting performance of concrete can be sustained under the network conductive effect and the tunneling effect, and the mass conductive concrete has great functions in the aspects of electrical engineering, industrial static electricity prevention, inside diagnosis of hugestructures, snow removal on pavements in winter and the like and has broad application.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to large-volume conductive concrete based on ironmaking dust removal dust. 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, electronic equipment will be ...

[0004] (2) Electrothermal effect: After my country enters winter, there are more rainy and snowy weather and lower temperature, especially in the northern region, where rain and snow are easy to accumulate on the road surface, which brings great inconvenience to the normal life of citizens

[0006] To sum up, conductive concrete has broad application prospects in roads, bridges and other large-scale infrastructure and buildings. At present, there is no coal combustion flue gas from thermal power generation, and waste generated by blast furnace ironmaking, such as ironmaking dust Other raw materials to prepare conductive concrete related research reports
