Comparatively Study of Non-Destructive test with different methods in various curing days [PDF]
In non-destructive testing, materials, components, or assemblies are inspected, tested, or evaluated without being destroyed. In nondestructive testing, materials, components, and assemblies are evaluated for quality and integrity without damaging them ...

Estimation of Mechanical and Durability Properties of Self-Compacting Concrete with Fibers Using Ultrasonic Pulse Velocity [PDF]
This study addressed the efficiency of ultrasonic pulse velocity (UPV) as a nondestructive test in concrete in estimating the mechanical (compressive and tensile strength) and durability (water absorption) properties of fiber-reinforced self-compacting ...

Compressive Strength and Ultrasonic Pulse Velocity of Concrete with Metakaolin [PDF]
The intention of the present study is to assess the possibility of using Metakaolin as a partial replacement of Portland Pozzolana Cement (PPC) in the concrete to improve its workability and compressive strength. It also explores the study on the connection between ultrasonic pulse velocity (UPV) on different replacement percentage of mineral ...

Frost influence on the ultrasonic pulse velocity in concrete at early phases of hydration process
Quite often concrete strength parameters have to be determined at an early age. Due to the strong correlation existing between the mechanical and acoustic properties of concrete, ultrasonic devices can be used for this purpose.
