To study the seismic performance of hollow columns with fiber lightweight aggregate concrete, a quasi-static test on eight concrete under lateral low-cycle reversed loading and axial force is presented in this article. The effects dosage plastic-steel fibers (0, 3, 6 9 kg/m3, respectively), steel (25, 50 75 respectively) compression ratio (0.4 0.6, mechanical properties such as capacity load, s...

Aims: In this study, the mechanical characterization of no-fines concrete solutions is addressed experimentally, with purpose possibly increasing their strength by using silica fume and embedded fibers (steel nylon fibers) as possible efficient reinforcement. Background: Due to competition between developed advanced countries, contemporary construction sector currently experiencing a shortage f...

As a low-carbon ecological cement-based material, SAC (sulfoaluminate cement) has become research hotspot. This study developed SAC-based high-performance concrete material with good durability and high toughness. The mechanical properties of different scales MSF (macro steel fiber) mSF (micro reinforced sulfoaluminate composites were mainly studied, including their compressive strength, flexur...

The development of cracks in concrete structures is one the significant issues with maintaining high strength after hardening. One way to prevent and control this problem use fibers. This paper investigates containing electric arc furnace slag aggregates reinforced fibers used study are steel three kinds polypropylene fibers; polyolefin (modified polypropylene), homopolymer, high-toughness poly...
