摘 要:納米微珠是從燃煤電站排放的煙霧中收集的超細微粒, 平均粒徑≦1.0μm, 表面為玻璃體, 呈球狀。納米微珠代替部分水泥摻入混凝土中, 可降低用水量, 增大流動性, 提高混凝土的強度和耐久性,是混凝土低碳技術的新組分。同時介紹了納米微珠在高性能混凝土及超高性能混凝土中的應用。
Abstract: 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 application of N-MB is introduced in the high performance concrete and ultra- high performance concrete.
