Concrete is a material whose properties depend on its initial formulation, conditions of use, and change over time depending environment the different types degradation that it likely to undergo. Knowledge monitoring various mechanical are therefore essential for maintenance civil engineering works. All concrete assessment methods, whether destructive or non-destructive, can then provide valuab...

development of ultrasound technique has not been progressing for evaluating the internal quality of fruits as fast as that of processed foods. in this research for quality assessment of pear fruit (shah miveh variety) an ultrasonic measurement system was constructed to transmit and receive the ultrasonic waves. the apparatus included a pulser-receiver, a pair of 75 khz ultrasonic transducers wi...

ultrasonic testing (ut), a nondestructive testing (ndt) method, is under development for quality determination of agricultural products, although it has long been used in the food industry. determination and measurement of product quality are important in modern agricultural research. noninvasive/nondestructive quality determination is a novel aspect of the postharvest process in which paramete...

This paper has carried out an experimental program to establish a relatively accurate relation between the ultrasonic pulse velocity (UPV) and concrete compressive strength. The involved testing cubes of (100) mm prisms (100×100×300) cast with specified test variables. samples are tested by using equipment two methods, direct (DUPV) surface (indirect) (SUPV) for each sample. obtained results we...

Burnt clay bricks are widely used as a construction material in Pakistan, and their testing for quality confirmation is frequently needed new old existing structures. The destructive methods time-consuming not always feasible the current study investigated feasibility of using ultrasonic pulse velocity (UPV) test non-destructive technique to assess both masonry A relationship was developed afte...
