Improvement of hydration products for self-compacting concrete by using magnetized water

نویسندگان

چکیده

Magnetized water (MW) is one of the most effective and economical ways to improve properties self-compacting concrete (SCC). Therefore, aim this study fresh, mechanical, microstructural SCC using MW. For purpose, a total 12 mixes were produced with silica fume (SF) content (5% 10% by weight cement), mixing passed through permanent magnetic field (with strength 1.4 T) for 50, 100, 150 cycles. Tests performed fresh (Slump flow, T50cm, V-funnel, L-box), mechanical (compressive, flexural, tensile strength), microstructure (SEM, EDX, TGA/DTG). The optimum result in compressive was achieved mix M8 5% cycles properties, M4 without SF had workability enhanced 11% compared control mix, SEM EDX tests indicated that prepared MW more C-S-H, less CH, denser. In addition, TGA/DTG analysis showed rate hydration reached 61% at 28 days.

Self-Compacting Concrete - Procedure for Mix Design

Self-compacting concrete is a fluid mixture suitable for placing in structures with congested reinforcement without vibration. Self-compacting concrete development must ensure a good balance between deformability and stability. Also, compactibility is affected by the characteristics of materials and the mix proportions; it becomes necessary to evolve a procedure for mix design of SCC. The paper...

Properties of Self-compacting Concrete – an Overview

Self-compacting concrete can be defined as the concrete which requires no vibrations and can flow around obstructions, encloses the reinforcement and fills up the formwork completely under its self weight. Over the last ten years, significant amount of work has been carried out on self-compacting concrete all over the world. In countries like Japan, Sweden, Thailand, UK etc., the knowledge of S...

Experimental Investigation on Self Compacting Concrete Using Quarry Dust

This study presents an experimental investigation on self-compacting concrete (SCC) with fine aggregate (sand) replacement of a Quarry Dust (QD) (0%, 25%, 50%, 75%, 100%) and addition of mineral admixtures like Fly Ash (FA) and Silica Fume (SF) & chemical admixtures like super plasticizers (SP). After each mix preparation, 45 cubes specimens and 45 cylinders specimens are cast and cured. The sp...
