【摘要】：檢測(cè)了鉻鐵渣粉的化學(xué)成分、氯離子含量、放射性、需水量比、活性指數(shù);對(duì)比了不同摻量下,鉻鐵渣粉和Ⅰ級(jí)粉煤灰對(duì)混凝土物理力學(xué)性能的影響。檢測(cè)結(jié)果發(fā)現(xiàn),鉻鐵渣粉的氯離子含量和放射性符合國(guó)家標(biāo)準(zhǔn)規(guī)定。與粉煤灰的對(duì)比實(shí)驗(yàn)發(fā)現(xiàn),鉻鐵渣粉的活性指數(shù)高于Ⅰ級(jí)粉煤灰;在混凝土中適量摻入鉻鐵渣粉有利于提高混凝土的力學(xué)性能。
[Abstract]:The chemical composition, chloride ion content, radioactivity ratio, water demand ratio and activity index of ferrochrome slag powder were tested, and the effects of ferrochrome slag powder and grade I fly ash on the physical and mechanical properties of concrete were compared. The chlorine ion content and radioactivity of ferrochrome slag powder are in accordance with the national standard. Compared with fly ash, the activity index of ferrochrome slag powder is higher than that of grade 鈪，
