一种长江隧桥专用掺合料及其生产方法
摘要：
一种长江隧桥专用掺合料，由矿渣、辅助材料和粉煤灰组成，其含量按重量百分比为矿渣65－74％，辅助材料1－10％，其余为粉煤灰。本发明的长江隧桥专用掺合料的生产工艺是：矿渣微粉的粉磨；粉煤灰的粉磨；矿渣微粉和粉煤灰的混合搅拌；散装发运出厂。本发明能提高了混凝土在水工工程特别是江海结合部工程混凝土的防渗抗裂、抗冲刷等耐久性能，保证混凝土结构在江海结合部环境下的耐久性；能有效提高了钢铁企业的固体废弃物处理水平，具有深远的环境意义；生产过程能耗低，且不消耗煤、石油等能源，对环境污染小；成本较低，可以有效降低混凝土成本，社会效益明显。
摘要（英）：

The admixture for Changjiang tunnel and bridge consists of mineral slag 65-74 wt%, auxiliary material 1-10 wt% and flyash for the rest. Its production process includes pulverizing mineral slag, pulverizing flyash, mixing mineral slag powder and flyash powder, and packing. The admixture can raise the antiseepage, anticracking, antiscouring and other lasting performance of concrete in hydrotechnic engineering, especially in the water contacting part. In addition, the present invention treats solid waste from iron and steel enterprise, and is environment friendly.
