Abstract
In this research, an experimental study of the properties of self-compacting mortar with Nano blast furnace slag has been done. Nano blast furnace slag was prepared and used as an additive to the self-compacting mortar in (1, 2, 3, 4, 5) % by weights cementitious sustainable materials. Blast furnace slag was crushed and milled until achieving to Nano particle size, Nano particle size was provided and checked by Laser Particle Size Analysis, AFM, and FESEM. Self-compacting mortar was tested at 7, 28, and 90 days’ age. Fresh properties of self-compacting mortar were determined by using mini flow table test and mini v-funnel test. The experimental results of self-compacting mortar shown that the mechanical properties include compressive strength, flexural strength, and direct tensile strength were increased as Nano powder percentage increases. The physical properties such as total water absorption and porosity was decreased as a Nano powder percentage was increased. While the density of self-compacting mortar increased as Nano powder percentage increase. The microstructure homogeneity and Nano powder distributions of self-compacting mortar were explained by using FESEM.
