Study of the Effect of Metallic NANO-Modifier on the Properties of Self-Compacting Concrete Using Portland cement, Rice Husk Ash and Quartz Flour

7 cubes were collected as the study aims to study of the effect of metallic nano-modifier on the properties of self-compacting concrete using Portland cement, rice husk ashes it was based on Portland cement Spassky brand CEM I 42.5N. It has been concluded that crop waste can be used as an alternative to Portland cement in self-compacting concrete that keep as Mechanical and operational properties of concrete and ready-mix concrete. The specific surface area of the ash was increased by mechanochemical activation. The use of rice husk ash (RHA) - a by-product of the rice industry - when added in the production process of high-performance concrete helps enhance the properties of concrete, as well as providing a host of important advantages to the concrete industry
