Ultrasonic pulse velocity data for Maitland and Stellawood cemeteries, and laboratory experimental data to establish ultrasonic pulse velocity equipment limitations

Cemeteries were used as time-series laboratories to assess weathering effects on gabbro stone as a function of different climatic forcings. Tombstones were measured using ultrasonic pulse velocity, which is a recognised assessment proxy for material structural integrity. In order to use this technique, it had to be carefully studied so as to limit experimental error, and then deployed in the field at cemeteries in different locations. The files presented here show the following:Lab work: experiments were carried out to assess the effects of ultrasonic couplant and transducer alignmentField work: An array of tombstones at Maitland Cemetery (Cape Town) and Stellawood Cemetery (Durban) were assessed using the developed experimental method.

墓地被用作时间序列实验室，以评估不同气候因素对辉长岩石的风化效应。通过对墓碑进行超声波脉冲速度测量，该技术被公认为评估材料结构完整性的有效代理。为了应用此技术，必须对其进行细致研究以限制实验误差，并在不同地点的墓地现场实施。此处展示的文件包含以下内容：
实验室工作：进行了实验以评估超声波耦合剂和换能器对准对效果的影响
实地工作：使用开发的实验方法对梅特兰德墓地（开普敦）和斯泰拉伍德墓地（德班）的一组墓碑进行了评估。
