Ultra-high performance concrete prepared from modified volcanic limestone powder
The invention discloses ultra-high performance concrete prepared from modified volcanic limestone powder. The ultra-high performance concrete is prepared from 52.5-grade Portland cement, modified volcanic limestone powder, slag powder, silica fume, metakaolin, quartz sand, a polycarboxylic water reducer, magnesium silicate, graphene oxide, polycarboxylic acid modified nano C-S-H and water. The modified volcanic limestone powder is utilized to enhance the characteristics of of the ultra-high performance concrete including good fluidity, high strength and low preparation cost, so that the popularity and market competitiveness of the ultra-high performance concrete prepared by the invention are favorably improved. Therefore, the ultra-high performance concrete prepared by the invention is concrete with high comprehensive performance.
本发明公开一种利用改性火山灰岩粉制备的超高性能混凝土，包括52.5级硅酸盐水泥、改性火山灰岩粉、矿渣粉、硅灰、偏高岭土、石英砂、聚羧酸系减水剂、硅酸镁、氧化石墨烯、聚羧酸改性纳米C‑S‑H、水。本发明中利用改性火山灰岩粉增强了超高性能混凝土具有流动性好、强度高以及制备成本低等特点，从而有助于提高本发明制备的超高性能混凝土的知名度以及市场的竞争力。因此，采用本发明制备的超高性能混凝土是一款综合性能高的混凝土。
