Investigation on Strength Characteristics of Self Compacting Concrete incorporated with AR Glass Fibers

Abstract

This project presents the experimental study on self-compacting concrete (SCC) with replacement of cement by various percentage of Silica Fume and Fly Ash. The main objective is to determine the Flexural strength, Compressive strength and Split tensile strength of Self compacting concrete by partial replacement of cement by Silica Fume and Fly Ash. The use of fly ash in concrete today is an important subject and is of growing importance day by day. Using fly ash in concrete many provide both economic advantages and enhanced properties in the production of concrete. The addition of super plasticizer increases the workability of concrete. The work involves making seven types of SCCs mixes. For each mix preparation, twenty-one cube specimens, twenty-one-cylinder specimens and twenty-one beam specimens are cast and cured. The specimens are cured in water for 7 days, 14 days and 21 days. The results show that SCC with 5% SF and 10% gives higher values of Compressive strength, Split Tensile strength and Flexural Strength compared to other percentages of Silica Fume and Fly Ash. According to the SCC result, various percentages of AR Glass Fiber (0.1% to 0.4%) added with the optimum SCC (5% of SF+ 10% of FA) and super plasticizer is mixed with optimum SCC. After each mix proportion, specimens are cast and cured for 28 days in water and hardened properties are determined. The results show that the higher the percentage of glass fiber, the higher the values of concrete Compressive strength, Split Tensile Strength and Flexural Strength.

Effects of Aloe Vera Mucilage as a Superplasticizer on Limestone Calcined Clay Self-Consolidating Concrete Performance

“…Thus, the resulting product SCC can provide good rheology and workability [9]. SCC offers several advantages over conventional concrete, including saving on project time cost, vibrating machines cost, and lowering skilled labor costs [10]. Nevertheless, since it generally requires a larger amount of binder and chemical admixtures than ordinary concrete, its material cost is typically 20-50% higher [11].…”

Aloe Vera-Based Concrete Superplasticizer for Enhanced Consolidation with Limestone Calcined Clay Cement

“…Comprising cement, fine and coarse aggregates, and water, SCC achieves its desired properties through admixtures such as superplasticizers [8], ensuring good rheology and workability [9]. SCC provides advantages, including time and machinery cost savings and reduced skilled labor expenses [10]. However, its material cost is typically 20-50% higher due to increased binder and admixture requirements [11].…”
