AL6061/Al2O3-Ash Reinforced Composites: An Experimental and Statistical Study Using Ultrasonic Stir Casting
Abstract: This study presents an experimental investigation on the influence of fly ash particle size on the mechanical properties of aluminum alloy (Al6061) composites fabricated through Ultrasonic Assisted Stir Casting. Fly ash, a low-cost and low-density by-product of thermal power plants, has emerged as an effective reinforcement material due to its excellent fluidity, high filling capability, and ease of processing. It has been increasingly utilized in metal, polymer, and rubber composites …

Design of a Geopolymer Based on Fly Ash and Metakaolin with a Solid, Liquid, and Powdered Alkaline Activator at High Temperatures
Abstract: In this work, the fresh and hardened properties of geopolymer concrete activated using solid, liquid, and powder alkaline activator systems, including fly ash and different amounts of metakaolin, are examined. Compressive and flexural strengths were assessed at 7 and 28 days in accordance with IS 516 (1959). Workability was evaluated using a slump test in accordance with IS 1199 (Part 2): 2018. At an ideal replacement level of 30%, the …

Geopolymer Concrete Composites and its Properties- A Clean and Sustainable Development
Abstract: Production of geopolymer composites, an inventive and environmentally friendly substitute for regular Portland cement concrete, involves the polymerization of several industrial waste materials, including fly ash, powdered granulated blast furnace slag, silica fume, and rice husk ash, using solutions that are very alkaline. Because this technique removes the requirement for calcination, which is a significant contributor of CO2 emissions during the manufacturing of OPC, GPC is more ecologically friendly. Alkaline …

Experimental Research on the Strength Properties of Concrete with Recycled Aggregate, Pond Ash, and Rubber Powder Replaced in Part for Concrete Materials in Standard Grades
Abstract: Concrete, a fundamental material in modern construction, poses environmental concerns due to its significant carbon footprint. To mitigate this impact, researchers explore alternative materials like fly ash, GGBS, alcofine, and rubber powder as cement replacements. This study examines the durability and strength of concrete that contains recycled aggregate, pond ash, and waste rubber powder. Waste rubber, abundant from industrial and automotive sources, poses disposal challenges. Pond ash, a byproduct of …

Analytical exploration of self-consolidating concrete (SCC) mix proportions via the Taguchi method
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 …

Durability Assessment of Self Compacting, Self Curing Concrete Incorporating Crushed Rock Powder and Mineral Admixtures
Abstract: Curing plays a crucial role in achieving the desired strength, characteristics, and durability of concrete. Negligent curing practices can lead to adverse effects on hydration and mechanical properties of concrete. In recent times, self-curing concrete has gained significant attention due to its potential in reducing water loss through the use of self-curing agents. The Present Research study focus on investigation on durability characteristics of self-curing self-compacting concrete using crushed rock …
