Abstract:This study reports the effects of packing of aggregate phase on the fresh and hardened state properties of high performance self-consolidating mortar (SCM) systems. The sands of five different gradings were utilized in this study. The final grading curves were obtained using Modified Andreassen model by varying its distribution modulus (q) from 0.20 to 0.50 so as to find its optimum value for maximum packing density of aggregate phase. The experimental results showed that the maximum packing density of sand used in research occurs when the distribution modulus (q) has a value of 0.35 in the Modified Andreassen model and that the total flow of the self-consolidating mortar (SCM) formulations increased with the increase in the packing density of sand in the SCM formulations while the V-funnel time reduced. The strength results showed improvement with higher packing degrees of mixes.
