Properties and Microstructure of High Strength Concrete Incorporating Different Supplementary Cementitious Materials
The construction industry has recently focused on the use of sustainable and innovative building materials, which called for the production of many supplementary cementitious materials with concrete to make the concrete produced durable and sustainable. Since high-strength concrete has many advantages other than its high strength, it has recently been used in non-traditional applications after for a long time confined to well-known traditional applications. This study presents the effect of micro Ferrosilicon (FS) and mineral materials on high-strength concrete properties, where silica fume (SF), FS, and metakaolin (Mk) were used as additives to cement.Besides the consistency test, all-ages compressive strength, splitting tensile strength, modulus of elasticity strengthand water permeability were investigated on the produced HSC.Microstructure analyses are carried out by SEM and EDX tests. The results showed a continuous decrease in a slump with the increase in mineral material, however, 15% FS and 15% MK were determined as the optimum percentage of the desired mechanical property. HSC performs up to 88 MPa compressive strength, 7.49 MPa tensile strength, and 39.89 GPa modulus of elasticity, as well as good durability properties. Finally, the high-strength concrete under consideration is suitable for use in both conventional and non-conventional applications and supports sustainable development and infrastructure development.
