Model Based Controller Design for Position Control of Servo Controlled Hydraulic Actuator against Air Entrainment
Abstract: Position control is important for numerous industrial and aircraft applications. Electro-hydraulic actuators are used for position control for advantages they provide over other actuation systems. The hydraulic fluid used for actuation, though desired to be incompressible, has some compressibility in practice. Entrainment of air in the fluid increases compressibility effect by reducing the effective bulk modulus. Reduced bulk modulus makes position control difficult. The paper studies the effect of effective …

Mechanical Properties of Aerated Concrete
Abstract: Nowadays it is very important to make the concrete economical. Aerated concrete is ordinary concrete that contains controlled amounts of air in the form of microscopic bubbles and having low density as compare to conventional concrete. These intentionally entrained air bubbles are extremely small. By using Air Entraining Agent (AEA), cement, coarse aggregate, fine aggregate and water we create aerated concrete. The experiment is perform on aerated concrete which is …

Feasibility Study of Reetha Powder (Sapindus trifoliatus) as a Plasticizer Admixture in Concrete
Abstract: With on-going research and development activities in the field of concrete admixtures, emphasis is laid on use of naturally available organic material to enhance properties of concrete. Reetha (Sapindus trifoliatus), is popularly used in ayurvedic medicines such as shampoo and other products because of its excellent foaming and cleansing properties. This study emphasizes on the effect of natural admixtures such as reetha powder concrete (RPC) in comparison with super plasticizers …

Improving the Performance of Self-compacting Concrete Using Optimized Admixture Combinations
Abstract: This study explores the influence of various admixture combinations on the performance of Self-Compacting Concrete (SCC), with an emphasis on its flow behavior, compressive strength, tensile strength, flexural strength, and resistance to impact. Various admixtures, including Air-Entraining Agent (AEA), Water-Reducing Plasticizer (WPC), Retarder (RET), and Accelerator (ACC), were incorporated into the SCC reference mix (SP + VMA) to evaluate their impact on SCC performance. A series of tests—such as slump …
