Embodiment 1～3

[0032] Embodiments 1-3 Preparation of special admixture for high-performance conductive concrete based on ironmaking dust removal ash

[0033] Get the fly ash and blast furnace slag powder of a certain power plant, carry out drying treatment to fly ash and blast furnace slag powder according to the technical index in table 1 and table 2, control its moisture content within 1%; Dry the fly ash Dry mix with blast furnace slag powder and ironmaking dust removal ash according to the ratio, and the mixing time is 10 minutes. Among them, ironmaking dust removal dust is calculated by mass percentage, including: carbon content of 5% to 65%, iron content 10% to 60%, and the balance is impurities; then add 10 parts, 20 parts, and 30 parts of copper fiber, 10 parts of polyphenylene vinylene, and 5 parts of polyvinylpyrrolidone for dry mixing for 15 minutes. The mass ratio is as shown in Table 3 Show.

Abstract

The invention discloses an admixture for high-performance conductive concrete based on ironmaking dedusting ash and a preparation method thereof. The admixture is prepared from, in parts by mass, 100-150 parts of fly ash, 45-80 parts of blast furnace slag powder, 10-25 parts of the ironmaking dedusting ash, 10-30 parts of copper fiber, 1-15 parts of polyphenylacetylene and 1-15 parts of polyvinylpyrrolidone. The special admixture for high-performance conductive concrete based on ironmaking dedusting ash can be used for cement concrete, the multi-composition effect of the admixture is played, the anti-penetrability performance, the anti-freezing performance and the conduction performance of the concrete are improved, hydration heat of the concrete is reduced, high-quality concrete raw materials are provided for urban buildings and structures, and the preparation method is simple and facilitates large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an admixture for high-performance conductive concrete based on ironmaking dust removal ash and a preparation method. 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...
