Comparatively Study of Non-Destructive test with different methods in various curing days [PDF]

open access: yesE3S Web of Conferences
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 ...

Statistical Equations to Estimate the In-situ Concrete Compressive Strength from Non-destructive Tests

open access: yesJournal of Engineering, 2018
The aim of this study is to propose reliable equations to estimate the in-situ concrete compressive strength from the non-destructive test. Three equations were proposed: the first equation considers the number of rebound hummer only, the second equation

Compressive Strength and Ultrasonic Pulse Velocity of Concrete with Metakaolin [PDF]

open access: yesCivil Engineering and Architecture, 2020
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

open access: yesCase Studies in Construction Materials, 2021
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.
