主　　题：Alccofine high strength mortar efficiency factor dilution effect 

摘      要：Previous studies on concrete have identified silica fume(SF)as the most effective supplementary material,whereas fly ash(FA)and slag have been identified as economical materials with long term strength *** of blended cement mortar referred to as blended mortar(BM)requires similar *** present study explores the application of Alccofine(AL)as supplementary material and compares its performance with conventional materials namely SF,FA and ground granulated blast furnace slag(GGBS).The mortar specimens with binder to fine-aggregates(b/f)ratio of 1:2 are prepared at water to binder(w/b)ratios of 0.4 and *** strength values and stress-strain curve for control and BM specimens are obtained at 7,28,56,and 90 d curing *** assessment based on strength activity index,k-value method and strength estimation model confirms that AL,despite lower pozzolanic activity,contributes to strength gain,due to reduced dilution *** of stress-strain curves suggests that the effect of w/b ratio is more dominant on the elastic modulus of BM specimens than on control *** observations from the study identify enhanced strength gain,improved elastic modulus and higher energy absorption as key contributions of AL making it a potential supplementary material.
