Characteristics of Sustainable Concrete Containing Metakaolin and Magnetized Water

In this study, fourteen sustainable concrete mixes containing metakaolin (MK) as supplementary cement material (SCM) and magnetized water (MW) mixing were designed, prepared, tested, analyzed, compared. The MK was used a partial replacement of weight by 5%, 10%, 20%, an additive to 20% weight. MW fully replace tap (TW) in prepared using two different magnetic fields 1.4 tesla (T) 1.6 T. This experimental research aimed assess the characteristics manufactured with MW. mechanical durability fresh hardened measured for assessment. Microstructural chemical analyses carried out on selected materials mixes. workability compressive strength at 7, 28, 365 days measured, addition splitting tensile 28 flexural days. conducted 18 °C 100 study effect applied variables elevated temperatures. microstructural scanning electron microscope (SEM), energy dispersive X-ray (EDX), Fourier transform infrared (FTIR) spectroscopy. results showed that 10% best ratio which enhanced all when TW or used. Using instead increased properties about 32–35%. supported increase showing indications more C-S-H gel production less CH concrete. addition, fewer micro-cracks pores, relatively denser concrete, detected additive.
