Effect of Fly Ash, Silica Fume and Blast Furnace Slag on Mechanical Property of High Performance Concrete

Abstract

The use of mineral admixture such as fly ash, blast furnace slag and silica fume in making high performance concrete has increased. The objective of this study is to investigate mechanical properties of compressive strength, splitting tensile strength and modulus of elasticity of hardened high performance concrete.

Effect of different additives on high temperatures of concrete

“…Generally, the uses of pozzolanic or replacement cementing materials can enhance the durability and performance of concrete, as they increase the reaction of the cement paste during the hydration process. They also have a filling effect when they are mixed with concrete (Farzadnia et al , 2011; Okoye et al , 2016; Eom et al , 2013). Furthermore, there are numerous advantages through the use of pozzolanic or cement additives in concrete such as the following (Yazıcı, 2008; Thomas, 2013): Cement additives were used to achieve required concrete properties, and they can increase resilience in harsh environments, extending the life of the building and reducing costs and impact of maintenance of the environment, providing significant social and economic benefits. Silica fume (SF) can improve durability and increase the strength of concrete.…”
