Methodology for monitoring Cement Based Materials at Early Age combining NDT techniques

Ultrasonic Pulse Velocity—Compressive Strength Relationship for Portland Cement Mortars Cured at Different Conditions

“…As cement cures, it changes from a liquid state to a solid state; consequently, the acoustic waves show a faster travel response. Then, UPV can be used for monitoring cement-based materials at early age [51] and self-healing quantification [52].…”

Models for compressive strength estimation through non-destructive testing of highly self-compacting concrete containing recycled concrete aggregate and slag-based binder

“…Even though these indirect measures have long been employed, their progress in relation to their use and application in construction has been remarkable since 2000 [19]. Some new trends in this field include their successful use at evaluating the compressive strength of concrete at early ages [20,21], to study the spatial variability of concrete strength [22,23], especially in beams [24], and high-precision detection of micro-cracking within the damaged concrete [2,25], especially with UPV analysis [26].…”
