Various non-destructive monitoring methods have been proposed to evaluate the early-age
characteristics of cement paste, including the setting time and hardening, but the …

Prediction of compressive strength of concrete at early ages has attracted a lot of attention,
but several defects still remain in previous research using nondestructive techniques such …

The propagation of ultrasonic wave in cement paste is closely related to its physical
properties, and therefore shows a potential application in fields of online monitoring of …

Cement hydration induces microstructural evolution in cement-based materials, causing
setting and hardening. Various experimental techniques were proposed to evaluate the time …

This study proposes an innovative contactless ultrasonic system (CUS) for monitoring the
hardening behavior of concrete under accelerated curing, without any penetration or …

Small amplitude oscillatory sweep (SAOS) techniques have been identified as valuable non-
destructive methods to investigate the microstructure of cement pastes, but relatively few …

A novel horizontal omnidirectional piezoelectric ultrasonic transducer suitable for real-time
monitoring of hardened cement paste was developed. The ultrasonic technique was …

Underground mining operations need nondestructive test methods to assess placed backfill
strength development at early age (especially up to 1 week of curing time) so that they can …

We examine non-destructive testing (NDT) techniques that characterize the interlayer bond
quality of idealized 3-D printed concrete, simulating a layup bond, in-situ. An experimental …

Modulus of pavement materials is an important input parameter for the mechanistic design of
pavements. As the bound layers such as cement-stabilised materials fail in flexure, flexural …
