【摘要】 采用钢筋锈蚀快速试验方法(新拌砂浆法),检验了纯水泥砂浆以及分别掺加减水剂、阻锈剂、粉煤灰、矿渣粉、复合矿物质掺合料(粉煤灰+矿渣粉)、复合矿物质掺合料和阻锈剂、复合矿物质掺合料+NaC1+阻锈剂等不同胶凝材料砂浆中钢筋的电极电位随时间变化的关系曲线,由此得出,纯水泥砂浆、掺减水剂砂浆、掺阻锈剂砂浆以及掺复合矿物掺合料和阻锈剂砂浆对钢筋无害并有保护作用,其他砂浆中的钢筋会有锈蚀倾向。更多还原

【Abstract】 Applying a quick test for steel bar rusting has determined electrode potential curve with time diagrams of steel bars in mortar such as cement and those adding water-reducer,inhibitor of steel,fly-ash,slag powder,composite mineral blending materials(fly-ash+slag powder),and composite mineral blending materials +NaC1+inhibitor of steel etc.respectively.So we have reached the mortar such as cement mortar,and those adding water-reducer,inhibitor of steel,composite mineral blending materials and inhibitor of steel etc.respectively are unharmful,and have protection to steel bar.The steel bars in the other mortars have tendentiousness being rusted.更多还原
