Abstract—In this study, the effects of waste marbles as aggregate material on workability and hardened concrete characteristics of self compacting lightweight concrete are investigated. For this purpose, self compacting light weight concrete are produced by waste marble aggregates are replaced with fine aggregate at 5%, 7.5%, and 10% ratios. Fresh concrete properties, slump flow, T50 time, V fu...

This paper investigates the effect of fiber volume fraction on distribution in steel reinforced self-compacting concrete (SFRSCC) through experiments and numerical simulations. Three types SFRSCC beam specimens with different fractions (0.3%, 0.6%, 0.9%) were cut to expose fibers. The number orientation angle fibers sections determined by image analysis techniques. Fiber density, segregation co...

Abstract: A new reinforced SFRFLC (abbr. steel fiber reinforced full-lightweight concrete) superposed beam was proposed to sufficiently utilize the good peculiarities of ordinary concrete in compression and SFRFLC in tension, and reduce its self-weight. Experimental study was carried out on the flexural behaviors of reinforced SFRFLC superposed beams compared with reinforced concrete beams and ...

In this paper, modeling of high speed projectiles with different nose shapes, penetrating into steel fiber reinforced concrete is investigated. This is a novel study because it considers the length to diameter ratio of steel fiber as well as projectile length to diameter ratio and volume fraction of fiber used in concrete matrix on the impact resistance of steel fiber reinforced concrete fibers...

Strength capacity of reinforced concrete columns is very important to resists and transmit the external loadings. For Architects engineerings requirements use small cross section or in case poor control quality we need increase compressive strength a strengthening technique structural elements such as column. In present paper, behavior four steel fiber self-compact by one layer CFRP that wrappe...
