Abstract
The invention relates to steel slag concrete comprising the following components: cement, water, barite sand, stones, sintered pellets, a naphthalene high-efficiency water reducing agent, an expanding agent, and fly ash. The steel slag concrete has the advantages that the steel slag concrete is prepared by mixing the cement, water, the barite sand, the stones, the sintered pellets, the naphthalene high-efficiency water reducing agent, the expanding agent and the fly ash; the sintered pellets and the barite sand enable the density of the concrete to be effectively improved; with the use of the barite sand, the sintered pellets can be prevented from sinking, the separation resistance of the concrete is improved, and the amount of the cement is reduced; the fly ash effectively reduces the hydration heat of the concrete; with adulteration of the naphthalene high-efficiency water reducing agent, the work degree of the concrete is improved, the setting time of the concrete is delayed, the construction difficulty is effectively reduced, and the construction period is greatly shortened; and with reasonable utilization of the industrial waste residue sintered pellets, the energy is effectively saved, the environment is effectively protected, and the production cost is reduced.
Description
technical field [0001] The present invention relates to steel slag concrete. Background technique [0002] Most of the concrete used in the existing construction field is processed with sand, stones, water and cement according to the traditional process. Due to the difference in raw materials, the density of the concrete after production is high, and the anti-segregation performance of concrete is poor. The disadvantages of large amount of concrete and short setting time of concrete lead to difficult construction, long construction period, high cost investment, poor practical performance, low reliability and poor construction quality. Contents of the invention [0003] The technical problem to be solved by the present invention is that the post-pressure construction of the existing concrete leads to difficult construction, long construction period, high cost investment, poor practical performance, low reliability and poor construction quality, so as to provide steel slag c...
