Crimped and Hooked End Steel Fibre Impacts on Self Compacting Concrete

Abstract

Self-compacting concrete is gaining importance in recent years due to its highest versatility in replacing compacting equipment and there by reducing the constructional flaws. The only limitation of SCC of compromising with strength has been challenged by the addition of steel fibers in this paper. In this research work two types of steel fibers such as crimped type and hook end type are utilized in various proportions such as 0.4%,0.8%, 1.0% and 1.25%. SCC mandatory tests such as Flowing ability, filling ability and passing ability were determined and then the mechanical properties such as compressive strength and split tensile strength have been determined. Results show the unique variation with reference to the different type of fiber and different volume of fiber. This unleashes a lot of scope in the field of Fiber reinforced Self compacting concrete

Effect of mineral admixtures on the performance of self-compacting geopolymer concrete

“…However, the addition of more slag has been observed to reduce concrete slump and mortar flow. Moreover, increasing the alkaline liquid content has shown to enhance workability and setting time while reducing compressive strength.Fiber-reinforced self-compacting concrete exhibits lower shrinkage properties compared to standard Portland concrete, owing to the expansion of its chemical and molecular structures due to fiber content [4]. Furthermore, the replacement of fine aggregate with quartzite partially leads to increased strength properties [5,6].…”
