Nano micro-bead(N-MB) is a superfine glass bead from the smoke discharged by coal station,whose average particle size is ≦1.0μm.The surface of N-MB is vitreous body,which shows spherical.The mixed water for concrete can be reduced and the fluidity of concrete is increased when the N-MB is partly instead of cement and added into concrete.The strength and durability of the concrete will be increased by using the N-MB for concrete.And the N-MB is one new component in concrete low carbon technology.The applica-tion of N-MB is introduced in the high performance concrete and ultra-high performance concrete.
