In this paper, the effect of incorporation of different nano material to concrete and the mechanical and physical specifications of Boron Carbide nano-particles combined concrete is presents. The B4C nano- particles could be used moderately rather than cement by 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 weighing percentage. The specimens were treating by the water through 7, 14, 21 and 28 days. The obtained results show that the replaced nano-particles within 3% produce composite cementations and specifications improvement under water treatments. The replacement level of specimens has been optimized by water treatment to provide 2.5 weigh percentage.
