“…According to this phenomenon, this research is focused on the utilization of MD as an aggregate replacement against the fine aggregate portion of the SCC. In the study, it was also aimed to determine the influence of filling and pozzolanic abilities of the GBFS usage on the desired workability, durability and mechanical properties of SCC as prescribed in the previous studies [ 55 ]. According to fresh SCC results, the optimum MD usage is found as 10% while this replacement ratio is 20% for the GBFS.…”

Self-compacting concrete (SCC) is a special, highly fluid type of concrete that is produced using chemical additives. It is easier to pour and reduces defects arising from workability. Waste marble dust is generated during the production of marble using different methods, or during the cutting of marble in processing plants; however, the uncontrolled disposal of waste marble dust in nature is associated with some environmental problems. Cement and concrete technology is a field with potential for the utilization of these large amounts of waste. The present study explores the use of marble dust (MD) (an industrial waste generated in abundance around the province of Bilecik) and granulated blast furnace slag (GBFS) (another industrial waste product) in the production of SCC. In this study, MD and GBFS are used as fine materials in SCC mixtures, and the rheological and workability properties and other hardened concrete properties of the produced SCC specimens are tested. Additional tests are conducted to identify the durability of the specimens to sulfate attack, as well as their freeze–thaw and abrasion resistance, followed by microstructure tests to identify the effects of MD and GBFS on bond structure. The late-age performances of MD and GBFS were then examined based on the results of the durability tests. The presented results revealed improvements in the fresh and hardened properties of SCC produced using MD and GBFS.

“…The evidence of flow of mortar and its bleeding characteristics in QD series are observed by its slump flow T500 test . Lime stone powders indicate better shape when compared to quarry dust and the friction between the particles leads to the high flowability characteristics [19]. In V funnel test all the SCC composites satisfies the acceptance criteria of EFNARC specifications.…”

Self-compacting concrete is very popular in the field of concrete technology and it plays a significant role while placing the concrete in congested reinforcements. Self-compacting concrete could be produced with high fluidity and good cohesiveness, and it gets compacted by its gravitational force. This paper attempts to understand the influence of filler materials such as lime stone powder and quarry dust as a partial replacement of cement material. Selfcompacting concrete was produced by partially replacing the cement by 10%, 20%, 30% Lime stone and Quarry dust powder, and their influence on fresh properties such as passing and filing ability, flowability are examined as per European Federation of National Associations Representing for Concrete (EFNARC) guidelines. Results of fresh and hardened properties exhibited replacement up to 10% lime stone and quarry dust is the optimum level, and other replacement levels produced satisfactory results. Compressive strength, water sorptivity, and density values are marginally affected by the addition of 20% and 30% replacement of these filler materials.

“…However, SCC was first designed in 1988 in Japan. The immediate reason for undertaking work on the development of SCC was the need to eliminate the vibration process [6][7][8][9][10][11]. SCC technology has increased the concreting efficiency, reduced labor costs, and increased the quality of concrete after hardening.…”

The type of test ingredients used for obtaining self-compacting high-performance concrete (HPSCC) has been carefully selected to be universal. For this purpose, an extensive statistical analysis of the obtained results of the literature research was carried out. Then, universal and adapted to the typical range, highly fit statistical models are presented that can support the HPSCC design process for achieving high strength. For this purpose, a broad plan of statistical research was used, namely multivariate selection of sidereal points, which allowed the use of as many as five variable factors at three levels of variability. The sidereal points were equal to the respective minimum and maximum input values. Additionally, based on the analysis of variance (ANOVA) for factorial systems with the interaction of the obtained test results, the significance of the impact of the tested material factors on the compressive strength of the HPSCC tested was determined.
