钢渣复掺胶凝体系力学性能研究
|
摘要
为探究钢渣粉与矿物掺合料复掺组成胶凝体系的搭配比例。采用试饼法及雷氏夹法测试钢渣粉及复掺胶凝体系的体积安定性,通过力学性能表征选出适宜的钢渣研磨时间和钢渣粉复掺胶凝体系的搭配比例,并将复掺胶凝体系强度表征优选组与水泥颗粒粒度分布进行对比。试验结果表明:钢渣研磨时间宜采用30 min,钢渣粉与矿物掺合料复掺时,体积安定性均能满足规范要求。当钢渣粉和矿渣粉复掺比例为1∶1且占胶凝材料40%时、钢渣粉和粉煤灰的复掺比例为2∶1且占胶凝材料30%时、钢渣粉、粉煤灰和矿渣粉复掺比例为2∶1∶1且占胶凝材料40%时,以上3种复掺胶凝体系的力学性能和粒度分布均表现优异。
In order to explore the proportion of the steel slag powder and mineral admixture complex composition,in this experiment,the volume stability of the steel slag powder and the mixed cementitious system was tested by the test cake method and the Lei folder method.The suitable grinding time of steel slag and the proportion of steel slag powder were selected by mechanical property characterization,and the particle size distribution of cemented particles was compared with preferred group of strength characterization of mixed cementitious system.The results showed that the steel slag proper grinding time should be30 min and the volume stability can meet specification requirements when the slag powder and mineral admixture are mixed.When steel slag powder and slag powder mix at the ratio of 1 ∶ 1,accounting for40% of cementitious material,steel slag powder and fly ash mix at the ratio of 2∶ 1,accounting for 30%of the cementitious material and steel slag powder,steel slag powder,fly ash and slag powder mix at the ratio of 2∶ 1∶ 1,accounting for 40% of cementitious material,the mechanical properties and particle size distribution of the above three kinds of mixed cementitious system are excellent.
