Investigation of fresh & hardened properties of concrete manufactured with magnetically treated water

Abstract

The most crucial objective for civil engineers is to enhance the properties of concrete. The cement concrete industry has started using magnetic water technology, a new innovation, in recent years. By passing water through a magnetic field, this technology alters a number of its physical characteristics. As a result, the water cluster's molecular density drops from 13 to 5 or 6, lowering surface tension. This work examines the durability, workability, compressive, tensile, and flexural concrete strength that was combined with water treated with magnetic field- (MFTW). By putting normal water in a field of magnetism, MFTW was produced. One of the test factors was magnetic strength. Water’s magnetic pull & the water-to-binding agent ratio (W/B) were factors for testing. According to the results, concrete created using magnetic water had compressive strengths that were 10–23 percent higher, tensile strengths that were 7 to 27 percent higher and flexural strengths that were 10–14 percent greater than those of concrete manufactured with normal water. The finest boost in concrete's strength of compression is specifically seen between 0.8 and 1.2 T of water's magnetic strength. For replacements of magnetic water ranging from 30% to 90%, the specimen's durability yielded positive findings. Additionally, it has been observed that magnetic water improves the slump, fluidity and degree of hydration of concrete.
