We present a proof-of-principle study about the use of a sensor for the nondestructive monitoring of strength development in hydrating concrete. The nondestructive evaluation technique is based on the propagation of highly nonlinear solitary waves (HNSWs). which are non-dispersive mechanical waves that can form and travel in highly nonlinear systems. such as one-dimensional particle c... https://toyscyclers.shop/product-category/toddler-sleepwear/
