Study on the mechanical properties and pore structure of desert sand concrete (DSC) after high temperature

To study the mechanical properties and pore structure of desert sand concrete (DSC), the ultrasonic testing, mechanical properties and mercury intrusion experiments of DSC after high temperature were carried out with different temperatures and desert sand replacement rate (DSRR). The ultrasonic wave...
