鞍钢钢渣矿渣制备人工鱼礁混凝土复合胶凝材料
Preparation of Composite Cementitious Material for Building Artifical Reefs Concrete from Angang Steel Slag and Granulated High Furnace Slag
摘要
Abstract
81. 5% granulated high furnace slag, 5% steel slag and 12. 5% flue gas desulphurization ( FGD) gypsum was mixed with 1 % cement clinker. The compressive strength of the mixed cementitious material was 56.75 Mpa after cured for 28 d. The prepared cementitious material had low calcium content compared with normal P. 0. Cement and was suitable for producing artificial reel concrete. The effects of different ratios of steel slag and FGD gypsum on the strength of the mortar samples were also studied. The results showed that the strength of the mortar samples increased with increasing the content of steel slag, when the content of steel slag was less than 5% ,and the strength of the mortar samples decreased with increasing the content of seel slag when its content was more than 5% , while their strength droped sharply when the content of steel slag was more than 20%. The strength of the mortar samples was also prominently affected by the content of FGD gypsum. The compressive strength and flexural strength increased by 168% and 176% respectively compared with the samples without FGD gypsum when thecontent of FGD gypsum increased to 12.5%. Hydration processes of net slurry were analysized by XRD and SEM methods. The results showed that the early hydration products in the system were mainly Aft , and C-S-H gel. The strength growth was mainly contributed by these two phases.关键词
