STUDY ON MODIFICATION OF ADMIXTURE OF FLY ASH AND THREE KINDS OF BALLAST蒋永惠摘 要:<正>Composite function of chemical admixtureand technical wastes was applied to modify admixture of flyash and three kinds of ballast(called"FATB"for short).Theresults show that the modified FATB has the the characteristicsof early higher compressive strength,faster......
Effect of Nano Silica on Hydration and Microstructure Characteristics of Cement High Volume Fly Ash System Under Steam Curing马保国1,梅军鹏1,TAN Hongbo1,LI Hainan2,LIU Xiaohai1,JIANG Wenbin1,ZHANG Ting11...">The influences of nano silica(NS) on the hydration and microstructure development of steam cured cement high volume fly ash(40 wt%, CHVFA) system were investigated. The compressive strength......
(SEM) test, were performed on lead and zinc contaminated soils solidified/stabilized by fly ash. Test results show that UCS and the leaching characteristics of heavy metal ions of S/S contaminated soils are significantly improved with the increase of fly ash content. UCS of S/S soils firstly increases with the increase of the times of drying and wetting cycles, after reaching the peak......
