CONCRETE mixingThe aim of this study was to investigate the effect of different mix ratios on the mechanical properties of steel fiber-reinforced concrete (LSFRC) and to determine an optimum mix ratio. The effects of four factors, namely, fly ash content, volume fraction o...
Within the context of the performance-based seismic design (PBSD), it is crucial to determine the drift ratio limits of PVA-FRCs under different performance levels. In this article, seven PVA fibers and high strength steel bars reinforced concrete columns were designed, and the quasi-static test...

Behavior of reinforced concrete beams (steelratio = 1 percent) with recycled coarse aggregate under cyclicbendings has been experimentally investigated. Ch... S. MiyazawaT. Kuroi - セメント·コンクリ-ト論文集 被引量: 24发表: 1999年 Experimental Study on Seismic Performance of Steel Reinforced...
, the presence of shear may significance influence on torsional strength of fiber concrete beams. Present paper investigates the mechanical properties like as shear strength, and torsion strength of concrete with different types of steel fiber with c...
Ultra-high performance concrete (UHPC) has a very low water/cement ratio, high cement dosage and, when mixed with one or more of the available mineral admixtures (along with removal of any coarse aggregates), can generate a matrix with minimal internal pore space and optimal compactness, thus...
An experimental work was carried out to produce high performance concrete (HPC) using superplasticizer and silica fume reinforced with fiber. The variables studied were fibers type (steel fibers and polypropylene fibers), aspect ratio of steel fibers (60 and 100) and fiber volume fraction (0.0%,...
