Reinforcing index (RI) for a fibre reinforced concrete can be obtained through multiplying volume of fibre in percentage by aspect ratio. Is it possible to calculate RI for hybrid fibre reinforced concrete ?
Hi @Manju Soundar
Yes it is possible to calculate the fiber factor or RI for hybrid fibers.
Refer this journal they have done with hybrid fibers with RI value limiting upto 1.7
In this case, I think you have to include the modular ratio of the types of fibres used, e.g., if steel and polypropylene fibres are used, the equivalent reinforcing index may be calculated as follow:
R.I. = Vs Ls/Ds(Es/Es) + VpLp/Dp(Ep/Es)
The subscript s refers to steel and p to polypropylene fibers.
Hi, I think it is possible to homogenize the FRP- RC and then caculate the index.
