Predicting the Compressive Strength of Concrete By Ultrasonic Pulse Velocity

open access: yesIOP Conference Series: Materials Science and Engineering, 2021
Abstract The key resolution of non-destructive methods applied to concrete structures is to offer a suitable estimate of the quality of the material. One of the modern methods used in the test of concrete strength is the non-destructive testing applying the ultrasonic pulse velocity (UPV).

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.

An Investigation On Ultrasonic Pulse Velocity Of Hybrid Fiber Reinforced Concretes

open access: yes, 2016
Because of the easy applying and not costing too much, ultrasonic pulse velocity (UPV) is one of the most used non-destructive techniques to determine concrete characteristics along with impact-echo, Schmidt rebound hammer (SRH) and pulse-echo. This article investigates the relationship between UPV and compressive strength of hybrid fiber reinforced ...
