In the present study, performance of Reinforced Concrete (RC) beams which were strengthened with Ultra High Performance Fiber (UHPFRC) and dowels at interface was investigated. RC a length 2.2 m UHPFRC layers tensile side. Before application layers, between roughened. During testing, slips recorded using Linear Variable Differential Transformers (LVDTs). The tested under four-point flexural tes...

Micro silica (MS) is an extremely fine, spherical powder that is used as an additive for improving concrete performance. It is obtained as a by product of silicon metal and ferrosilicon alloy production.  Due to its pozzolanic nature, micro silica can be used to enhance the qualities of both  fresh  and  hardened  concrete. Addition of micro silica into the concrete as a cement rep...

High Strength Concrete (HSC) is defined as concrete that meets special combination of performance and uniformity requirements that cannot be achieved routinely using conventional constituents and normal mixing, placing, and curing procedures. It is a highly complex material, which makes modeling its behavior a very difficult task. This paper aimed to show possible applicability of Neural Networ...

high performance fiber reinforced cementitious composite (hpfrcc) materials exhibit strain hardening behavior with multiple cracking under tensile loading. in this paper, experimental and parametric studies are performed to assess the influence of using hpfrcc material instead of normal concrete in reinforced concrete beams. after calibrating the experimental results, the analytical results inc...
