Concrete structures are increasingly affected by fatigue damage, while new slender building with greater mechanical requirements make it necessary to deepen knowledge of their behaviour under loading. In this research, high-strength plain concrete was studied two different frequencies cyclic compressive stress. Wöhler curves were obtained in ways, on the one hand, applying a uniform frequency 1...

Abstract Many researchers have investigated alternative sources to overcome the problem of conventional building material polluting environment by development green self-compacting concrete in construction industry. The best solution is utilise non-conventional materials like agricultural wastes. Meanwhile, (SCC) considered as high strength well high-performance concrete. demerits, which includ...

The goal of this study is to assess the fresh and hardened properties self-compacting concrete (SCC) prepared using locally available materials. This research includes also impact polypropylene (PP), steel hybrid fibers on same properties. In addition, mechanical SCC specimens (with without fibers) at high temperatures, including as compressive, tensile, flexural strengths, will be determined. ...

In fiber concretes, microcracks in the boundary area between the cement paste and the surface of aggregates or fibers are higher. Natural and artificial pozzolans can be used for reinforcing this area. In this research, the combination of glass fiber, zeolite, and nano silica particles were used in lightweight self-compacting concrete containing scoria. Fiber volume fractions between 0% to 1.5%...

The reluctance in utilizing the advantages of Self Compacting Concrete (SCC) in Bahrain stems from two contributing factors: Lack of research or published data pertaining to locally produced SCC, and a feeling of doubt and uncertainty in the minds of practicing engineers about reliability and suitability of SCC in hardened stage. The primary aim of this study is to explore the influence of visc...

Concrete is a binding material, made up of constituent cement, fine aggregate, coarse aggregate and water. Self-Compacting an innovative concrete that does not require vibration for placing compaction. It able to flow under its own weight, completely filling formwork achieving full compaction, even in the presence congested reinforcement. The study also intended quantify amount plantain leaf as...

Self-compacting concrete is an innovative technology with higher flowability properties by adding the mineral admixtures such as superplasticizers and not necessary to vibrate concrete. The banana fibers were used in this investigation because fiber environmentally friendly material good compared synthetic fiber. experimental test consisted of two phases research, i.e., preliminary which had ai...
