Abstract

The accurate characterization of construction materials is crucial for ensuring their durability and performance in the construction industry. This study focuses on the non-destructive characterization of mortar using ultrasonic techniques to investigate the impact of sand grain size on ultrasonic properties. Using 1 MHz transducers, we observed significant non-linear variations in ultrasonic velocity, with a decrease to 3100 m/s at a particle size of 0.3 mm, followed by an increase to 3700 m/s as the grain size approached 0.7 mm. These results demonstrate a strong correlation between sand grain size and the ultrasonic properties of mortar, highlighting the influence of particle size on parameters such as transmission coefficient and acoustic impedance. By selecting appropriate sand grain sizes, the risk of cracking and degradation in mortar can be minimized, leading to improved durability and structural integrity. This study contributes actionable insights for optimizing mortar compositions, paving the way for enhanced construction materials.

研究砂粒度与砂浆超声性能的关系：超声技术的综合分析

建筑材料的准确表征对于确保其在建筑行业的耐久性和性能至关重要。本研究的重点是利用超声波技术对砂浆进行无损表征，研究砂粒度对超声性能的影响。使用1 MHz换能器，我们观察到超声波速度的显著非线性变化，当粒径为0.3 mm时，超声波速度降至3100 m/s，随后当粒径接近0.7 mm时，超声波速度增加到3700 m/s。这些结果表明，砂粒度与砂浆的超声性能有很强的相关性，突出了粒度对传输系数和声阻抗等参数的影响。通过选择合适的砂粒尺寸，可以将砂浆开裂和降解的风险降至最低，从而提高耐久性和结构完整性。这项研究为优化砂浆成分提供了可行的见解，为增强建筑材料铺平了道路。
