Influence of natural fibers on physical, mechanical, and fire‐resistant properties of microconcrete
Structural Concrete, EarlyView.Abstract This study examined the influence of natural fibers on the physical, mechanical, and fire‐resistant properties of microconcrete, in comparison with conventional polypropylene fibers used in cement composites. The fibers were characterized by FTIR and TGA/DSC to assess their composition and thermal stability, and FTIR was also performed after ...
