Summary:

This study investigates in using fibers to improve the cyclic behavior of concrete samples. Fiber concrete samples are categorized into three parts: recycled tire steel, carbon, and hybrid fiber reinforced concrete, each with five samples of varying volume percentages. With the help of laboratory data obtained from loading, cyclic properties and responses, such as maximum stress, plastic strain, dynamic elastic modulus, damage, and plastic strain energy, are evaluated. The most optimal mode is also introduced. On the other hand, data from the SEM method is used to determine how fibers and concrete interact.

Status: Analysis and writing the result of experimental test(this paper are preparing for construction and building material)

Mix Description:

Recycled Steel Fiber Reinforced:5 volumes content (0.1% to 0.5%)

Carbin Fiber Reinforced:5 volumes content (0.1% to 0.5%)

Hybrid Reinforced:5 volumes content (0.1% to 0.5%)

DIC analyses were conducted for macroscopic investigation, while SEM/FTIR analyses were performed for microscopic investigation.

The results and discussion parameters:

Unconfined compressive strength (UCS)/Maximum stress evolution/Damage growth with DIC/Plastic strain

dynamic elastic modulus/Plastic strain energy
