This study is about the estimation of the mechanical properties of cement grout material using a magnetic field treated water instead of tap water. The water that passed through a magnetic system is called MFTW. Similar research indicates that 5% of cement dosage can be saved by decreasing bleeding of concrete and improving resistance to freezing. The reason why MFTW can improve characteristics of concrete can be explained by molecular structure of water. Magnetic force makes water clusters into single molecule or small ones. Hence, the activity of water is improved by the magnetic force. While hydration of cement particles is on progress, the MFTW can penetrate the core region of cement particles more easily. Therefore, the hydration can be carried out more efficiently and the compression strength of concrete is highly improved. The sample of the sodium silicate cement grout's homogel using the MFTW results in highly compressive strength increases in compressive strength approximately from 20% to 50%.
