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%...

This study presents an experimental investigation on self-compacting concrete (SCC) with fine aggregate (sand) replacement of a Quarry Dust (QD) (0%, 25%, 50%, 75%, 100%) and addition of mineral admixtures like Fly Ash (FA) and Silica Fume (SF) & chemical admixtures like super plasticizers (SP). After each mix preparation, 45 cubes specimens and 45 cylinders specimens are cast and cured. The sp...

In order to model the effect of mixture parameters and material properties on the hardened properties of, prestressed self-compacting concrete (SCC), and also to investigate the extensions of the statistical models, a factorial design was employed to identify the relative significance of these primary parameters and their interactions in terms of the mechanical and visco-elastic properties of S...

Abstract Concrete with high ductility, workable, strength, easy to flow without compaction, and durable is a concrete need in the future. this quality, one of which make self-compacting (SCC). This paper reports performance self compacting (SCC) containing rice hush ash. Rice husk ash waste from burning husks. The purpose study was determine SCC addition specimens were made using (RHA) (NRHA). ...

The purpose of this study was to investigate the relationship between molarity and workability in Self-Compacting Geopolymer Concrete (SCGC), as well mechanical properties. Compressive strength split tensile tests are used characterize characteristics research. Additionally, investigates optimal for self-compacting geopolymer concrete. Fly ash lieu cement On new concrete geopolymer, is determin...

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...
