Influence of Magnetic Water on Self-compacting Concrete Using Sulphate Resisting Cement

Abstract

This paper aims to design a green and high-performance magnetic water concrete from normal materials used for manufacutring concrete. First, magnetic water was prepared by placing magnets into a beaker containing water of 985 Gauss magnetic field. Then, self-compacting concretes (SCCs) were produced with the optimal mix ratio of sulphate resisting cement (SRC), metakaolin, fine aggregate, coarse aggregate, micro steel fibers, super plasticizer and water. Next, a contrastive experiment was carried out between the SCC added with magnetic water, and that added with general water. The results show that the SCC prepared with magnetic water achieved a moderately better workability, 10% higher compressive strength, 5% higher tensile strength, and 6.74% lower price than the SCC prepared with general water. The research provides an innovative technique to build structures using high-performance material with low environment impact at a moderate price.
