剑桥大学Abir Al-Tabbaa教授来访我所

        5月23日，应顾凯博士邀请，剑桥大学工程系Abir Al-Tabbaa教授来访我所，并做了题为“Soil Mix Technology for Land Remediation - UK Perspective”的学术报告。Al-Tabbaa教授就其主持的SMiRT项目，详细介绍了英国在污染土修复技术方面进行的努力。报告结束后，顾凯博士代表研究所向Al-Tabbaa教授赠送了礼物。

    报告摘要：

        In-situ remediation of contaminated land with soil mix technology can deliver a    multi-technique remedial strategy on the same site combining smart low permeability barriers, permeable reactive barriers, stabilisation/solidification and soil amendment treatments as well as ground improvement, delivering significant advantages over alternative strategies.  This was the core objective of Project SMiRT (Soil Mix Remediation Technology) which involved the execution of the largest research field trials in the UK to provide field validation for this technique.  The project also involved equipment development, binder development, extensive laboratory studies and monitoring and assessment of the field performance. Around 800m3 of soil were treated on a contaminated site in Yorkshire in May 2011 with 6 different treatments testing ~40 binders and binder compositions and 10 different installation methodologies.  Field monitoring, testing and coring activities at the site took place twice: once 2 months after treatment and again in March 2014, with over 300m of cores obtained. This talk presents an overview of the project with a focus on the field trials activities and some of the results obtained.
