Strength Characteristics of hybrid fibre reinforced concrete

Deepa A Sinha

Abstract :

Extensive research is currently going on to evaluate and quantify advantages of fiber added concrete in general civil applications. Different fiber additives can be combined with concrete to design for specific applications and optimize mechanical properties. Hyids include the combination of micro synthetic fibers with steel fibers or micro synthetic fibers with macro synthetic fibers. A compromise to obtain good fresh concrete properties (including workability and reduced earlyage cracking) and good toughness of hardened concrete can be obtained by adding two different fiber types, which can function individually at different scales to yield optimum performance.. In this paper the optimum dosage of fibers to get maximum strength for the M 30 grade concrete is found and the properties of concrete i.e workability, compressive Strength, flexural strength are found.
