"The water is initially magnetized with the help of 0.5 horse power motor having a 1 and 3Tesla magnets at its inlet pipe. Concrete samples are then prepared and cured with magnetic water and normal water in four main different cases. About 36 concrete and mortar cubes are casted and tested for 7, 14 and 28 days." Results show that the compressive strength of concrete samples mixed with magnetic water is higher than those prepared with normal water. The compressive strength of concrete samples mixed with magnetic water at a magnetic strength of 1T increases by 10-20% more than that of normal water". Also, the consistency of fresh concrete is improved in case of magnetic water than that of normal water.

Different mixes were made with various amounts of NB at rates 10%,15%,20%,25% and 30%,by weight, as a partial mass replacement for cement. First group of samples were subjected to normal curing and tested after 7, 28, 90 and 180 days, while the second group of samples were subjected sulfuric acid of a concentration of 0.2 N and tested after the same ages. The hydration process and durability of samples were monitored using scanning microscope (SEM). The results of this study indicated that using NB as 15% partial replacement of cement improved durability and microstructure of concrete mixture against aggressive curing condition.
