Efecto del contenido de agua sobre la resistencia y la velocidad de pulso ultrasónico del concreto
The purpose of this study is to determine correlations among content of concrete water, compressive resistance and Ultrasonic Pulse Velocity (UPV). Cylindrical concrete specimens, 200 mm long and 100 mm in diameter made from a mixture of Portland cement type I, and a water/cement ratio (w/c) 0.5, ha...

| Summary: | The purpose of this study is to determine correlations among content of concrete water, compressive resistance and Ultrasonic Pulse Velocity (UPV). Cylindrical concrete specimens, 200 mm long and 100 mm in diameter made from a mixture of Portland cement type I, and a water/cement ratio (w/c) 0.5, have been studied. The curing of the specimens was performed under standardized conditions and indoor environmental conditions. It determines the water content in each specimen by difference in weight and subjecting them to UPV tests and to compressive resistance test during the first 28 days after the setting. The results show a model of logarithmic type that describes the relationship between the compressive strength with the water content of concrete and the UPV during the curing stages proposed. |
