Concrete Quality Evaluation Using Non-destructive Test
Abstract: This paper analyses the non-destructive testing (NDT) measurements used to assess on site strength and condition of reinforced concrete. To ascertain the residual strength of concrete, extent of corrosion, it is imperative to assess the health of the RC structural members of a building using State-of-the-art non-destructive testing (NDT). NDT of concrete structure is carried out in order to assess the health of structure without impairment of its desirable properties. …

Study on Electrical Resistivity of Metakaolin Concrete
Abstract: The present work studies the electrical resistivity of metakaolin concrete containing metakaolin at water–binder ratios 0.58, 0.55, 0.50 and 0.45. Cement was replaced with 0%–15% MK. The optimum replacement level was found 10%. Testing included measurement of electrical resistivity (ER), compressive strength and flexural strength (DT); rebound hammer; and ultrasonic pulse velocity test. ER increases with MK content, age and reduction in W/b ratio. The interrelation between ER and compressive …

Ballistic Impact Performance of Composite Armor Using Ultrasonic Nde and Ansys Autodyn
Abstract: The world is currently under the threat of terrorist attacks and wars. This will be very critical because the scientists have developed advanced weapons (guns, bullet) for the awesome attacks. Therefore, the safety of soldiers and vehicles of the army has become a major concern. Armors are used in defense applications to provide protection for soldiers and military vehicles. In general, armor is made from natural materials, composite materials and …

Studies on non-destructive inspection of steel wire ropes
Abstract: Non-destructive tests (NDT) of steel wire ropes under services are experienced to estimate remnant life with reference to new and similar components tested under similar conditions. Inspection by magnetic defect-stray fields’ to gamma radiography for imaging defects in addition, for suspended bridges have been methods of tests to configure defect morphologies in wires. This is beyond standard periodic inspections accounted from constrains of pre broken wires, multi-axial deformation, frictional wear, …

Strength & Durability of Concrete with Sand Blasting Residue
Abstract: Sand blasting residue (SBR) is commonly obtained as a by-product from chain manufacturing industries. Although it is a waste material but can be used in the mixing of concrete. The work has been divided into two parts. Part 1 covers preparation of M20concreteby substituting SBR as replacement of sand in different percentage such as 40%, 50%, 60%, 70% & 80%. The w/c ratio is kept as 0.5 with adequate does …

Assessment of M30 Concrete Compressive Strength Using Digital Rebound Hammer and Destructive Testing
Abstract: Abstract The assessment of in-situ concrete strength using non-destructive testing (NDT) techniques hasbecome increasingly important for quality assurance, structural evaluation, and conditionassessment of concrete infrastructure. Among the available NDT methods, the digital reboundhammer offers a rapid, economical, and non-destructive means of estimating concretecompressive strength. This study experimentally investigates the correlation between reboundnumbers obtained from a digital rebound hammer and the compressive strength of M30 gradeconcrete determined using a Compression Testing …

Structural Audit and Health Assessment of RCC Structure: A Case Study
Abstract: In India, where rapid urbanization and seismic risks are prevalent, ensuring the safety and longevity ofstructures is paramount. Structural audits and health assessments of reinforced concrete cement(R.C.C.) buildings are mandated by municipal authorities to evaluate their integrity. The objective is toextend the lifespan of structures while mitigating risks to human life and neighboring buildings. Non destructive testing (NDT) methods, including the rebound hammer test and ultrasonic pulse velocitytest, are widely …

Mechanical and Thermal Factors Contributing to Turbine Engine Failures
Abstract: Turbine engines are essential parts of aircraft and power plants because they operate in harsh mechanical and temperature environments, which increases the likelihood of their failure. This paper summarizes what is now known about the complex interactions between thermal loads and mechanical stresses in turbine engine breakdowns. Thermal aspects, such as thermal cycling, heat transfer methods, and cooling systems, are examined for their contributions to deterioration and structural integrity, while …

Review of Composites formed of Thermoplastic as Organic Fibers
Abstract: Composites made of structural monomers gave rise to thermoplastic polymers (TMCs). Due to their usage of a thermoplastic matrix, these materials really aren't chemically reactive. TMCs may be remoulded without degrading when heated and become softer. They harden into the final shape when they cool. Thermoplastic materials bonded with plant fibers may one day be used to create impact- absorbing structure for renewable power. Its impact features of organic fiber-reinforced …

Experimental and Numerical Analysis of RCC Beams Undergoing Four-Point Bending Tests: A Parametric Study of Acoustic Emission (AE) Techniques
Abstract: Reinforced concrete is a composite material where tensile reinforcement is added to increase its tensilestrength since plain concrete is weak in tension. Reinforced concrete has far more complicated behaviorthan plain concrete. This is due to the microstructural changes in concrete as well as the interactionand link between concrete and steel. Micro-cracking of concrete and steel yielding are the two mostcommon failure mechanisms in reinforced concrete. Reinforced cement concrete is a …

Bituminous of Plastic Road
Abstract: Transfer of waste materials, such as plastic sacks, has become a significant issue, and plastic wastes are singed for transport, causing severe environmental impact. The use of waste plastics in bituminous mixes has shown that they improve the blend's characteristics while also reducing transfer difficulties. Plastic garbage that has been separated and cleaned is sliced so that it can pass through a sieve with a size of 2 mm - …
