چکیده
The present experimental research aims to evaluate the effect of applying directly magnetic flux densities of 0.5, 0.8 and 1 Tesla (T) to fresh concrete specimens containing 5 and 10% silica fume (SF). Regarding this, compressive and flexural strengths tests were used to assess the mechanical properties of the concrete. Furthermore, durability, of concrete specimens exposed to magnetic fileds (MFs) was investigated using the electrical resistance and chloride ion penetration tests. In order to analyze the microstructure of concrete, scanning electron microscopy (SEM) images were taken from concrete specimens subjected to MFs. Finally, a method has been introduced to determine the flexural strength of concrete under the influence of MF, relying on its cylinder compressive strength. According to this study observations, optimal results were achieved through MF of 1 T and 10% SF replacement. Hence, applying MF of 1 T to concrete specimens incorporating 10% SF enhanced their compressive, flexural and electrical strengths by 24, 15 and 18%, respectively. Following this, depth of chloride ions penetration was decreased by 15%. The SEM analysis revealed that the microstructure of concrete exposed to MF becomes denser and less porous, supporting the mechanical and durability findings.

تازه های تحقیق
  • Applying the MFs to concrete specimens incorporating SF increased their durability in a NaCl environment.
  • A power equation has been proposed to determine the flexural strength of concrete with SF, which was subjected to the MF.
  • A large amount of C-S-H gel generated through MF in concrete significantly contributed to its improved mechanical strength and durability.
