Enhancing Concrete Performance Through Ternary Mixtures: Utilizing SCBA and Silica Fume for Sustainable ConstructionBy Ayushi Dehariya, Harsh Rathore
Abstract: This study investigates the effects of incorporating Sugarcane Bagasse Ash (SCBA) and Silica Fume (SF) as supplementary cementitious materials on the properties of concrete. Compressive strength, split tensile strength, and water absorption characteristics of ternary blended concrete mixes containing varying proportions of SCBA and SF were examined at curing periods of 7, 28, and 56 days. The results reveal that up to 15% SCBA replacement and 10% SF addition led …

Enhancing Compressive Strength and Durability through Optimization of Concrete MixturesBy Yash Dangi, Harsh Rathore
Abstract: This research investigates how varying cement-aggregate ratio, water-cement ratio, and slump height affect the compressive strength of concrete mixtures. Through an analysis of 36 samples, each representing different combinations of these parameters, significant insights are gained into the optimization of concrete mix designs for construction applications. The study reveals that higher water-cement ratios tend to decrease compressive strength due to increased porosity in cured concrete. Conversely, higher cement-aggregate ratios generally …

Analytical exploration of self-consolidating concrete (SCC) mix proportions via the Taguchi methodBy Mohd Babar Khan, Harsh Rathore
Abstract: To address the challenge of limited space within structural elements containing densely packed reinforcement, Self-Compacting Concrete (SCC) was developed. This study focuses on optimizing the experimentation process using Design of Experiments (DoE). Taguchi's standard L(3) orthogonal array (OA) was utilized, consisting of four factors with three levels each, resulting in nine trial mixes. The factors examined include water-powder ratio, cementitious material content, superplasticizer dosage, and steel fiber content. The aim …
