Abstract

Concrete is a widely utilized material in the building sector and it is a major source of pollution across the globe. The use of SCMs in concrete has been increasingly common in recent years, growing in tandem with the expansion of the concrete industry (Su et al. in Cem Concr Res 31:1799–1807, 2001) [1], as a result of discussions about issues such as raw material extraction, CO₂ emissions, and so on. These consequences created demands to reduce usage of cement-making raw materials by utilizing supplemental cementitious materials such as fly ash, micro silica, and so on. The waste materials from industries aid sustainable growth in the current environment (Jodeiri and Quitalig in J Civ Eng Res 2:100–107, 2012) [2]. The development of SCC resulted in a good perception of its numerous benefits such as reduced noise pollution. Construction time and power consumption are reduced as a result of vibration through the use of supplementary materials. By integrating maximum cement content with mineral admixtures, characteristics and self-compacting concrete are improved. For the concrete data gathered from the laboratory experimental work done in this study, a mathematical analysis employing statistical approaches for prediction of 28 days of strength of concrete was undertaken. The mix proportioning elements were the variables in the prediction models (Sabet et al. in Constr Build Mater 44:175–184, 2013) [3]. Multiple non-linear regression models produced high correlation coefficients for compressive strength prediction at various curing ages (28, 56, and 91 days) and for various modifications, such as using FA, GGBS, and Microsilica as partial substitutes for cement. In this paper, an experimental work was carried out on Compressive Strength of Quaternary Blended Self-Compacting Concrete (QBSCC) with mineral admixtures for 0.30 and 0.40 water-binder ratios with A simple mathematical model is used to estimate the concrete compressive strength based on the results of early age tests (Devi and Rao flexural behavior of quaternary blended fiber reinforced self compacting concrete slabs using mineral admixtures.
