摘要
Abstract
This study utilized vanadium-titanium tailings from the Panxi region as raw materials,aim-ing to activate their potential cementitious activity through physical and composite chemical modifica-tion techniques,thereby preparing vanadium-titanium tailings-based cementitious materials.By analyz-ing the micro-properties of the prepared materials,the hydration products and the evolution of micro-structures within the cementitious material system were explored.The research results indicate that after treatment with mechanical activation and composite chemical modification,the 28-day activity index of the vanadium-titanium tailings significantly increases from the original 60％to 84％.When the compos-ition is 45％vanadium-titanium tailings,20％titanium slag,5％calcium material,15％sulfur material,and 15％cement clinker,the prepared vanadium-titanium tailings-based cementitious material exhibits good mechanical properties with a 28-day compressive strength of 33.1 MPa,which is comparable to that of 32.5-grade cement.This indicates that the material has potential application prospects in non-structural engineering field.关键词
