چکیده
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. Four different mixtures are prepared, tested, assessed in order attain these goals. were heated various temperatures (200, 400, 600, 800) a rate 5 degrees Celsius per minute for each test. temperature was remained constant target one hour before cooling ensure consistent throughout specimen. According test results, all mixes have good consistency workability terms filling passing ability. inclusion lowered slightly. Also, strengths improved with increasing up 200 °C dropped over °C, according findings. Within SCC, PP removed risk spalling. Concrete containing finest characteristics spalling resistance rises. Weight losses lower than those fibers. As rose, lost mass UPV decreased until samples spalled (as plain or questionable fibers). Doi: 10.28991/cej-2021-03091779 Full Text: PDF

Ultra High Performance Self Compacting Concrete
Experiences in the development of Ultra High Performance Concrete found a very high flowability in concrete with low water powder ratio. Because of the high viscosity of the cement paste, compaction was necessary. To improve the compaction characteristics of the concrete the idea of adding coarse aggregate was developed. The first tests showed a good workability of the fresh concrete and a good...
متن کاملComparison of the Performance of Self Compacting Concrete
Self-Compacting Concrete Originally developed in Japan, SCC technology was made possible by the much earlier development of Superplasticisers for concrete. To compare the performance of SCC with Fly Ash 20%, Silica Fume 10%, Rice Husk Ash (5%, 10%, and 15%) as a partial replacement of cement, due to the high increase in construction which has brought a heavy demand for ingredients of concrete s...
متن کاملhybrid fiber reinforced self-compacting concrete: hardened properties
in most cases, fiber reinforced self-compacting concrete (frscc) contains only one type of fiber. the use of two or more types of fibers in a suitable combination may potentially not only improve the overal properties of self-compacting concrete, but may also result in performance synergie. the combining of fibers, often called hybridization, is investigated in this paper for a cimentetious mat...
