Nanoparticles and polymer for soil stabilization studies

软土地基强度低、压缩性大，给施工带来了很大的挑战。 在承载能力不足的土壤上的基础设施通常需要安装深基础，例如深桩，这并不总是经济或环境安全的。传统的缓解措施包括用水泥稳定具有挑战性的原生土壤，以改善其工程性能。由于高能源密集型制造工艺，水泥的使用对环境构成威胁，由此产生的高二氧化碳排放量令人担忧，开发可再生自然资源的进展缓慢也令人担忧。 这项研究将导致创新的方法，对环境无害的土壤稳定地面与软土沉积，通常表现出不良的工程特性。将进行广泛和系统的试验研究，通过评估稳定土的力学性能，确定各种稳定剂在土壤混合中的适用性和可行性。纳米颗粒将与许多土壤稳定剂混合，以有效地提高原生土壤的性能。该研究还将揭示纳米颗粒在加拿大乏燃料储存系统屏障中的影响，从而引领高性能先进屏障的建设。 从研究中获得的先进技术将提高土壤强度，允许在加拿大建造更安全的桥梁，高层建筑和交通系统。它将协助核废物管理组织发展加拿大危险乏燃料的安全储存设施。研究的技术成果将通过与工业界的积极合作用于应用开发。该计划将培训具有土壤稳定和屏障材料增强新技术专业知识的工程师和科学家。

The low strength and high compressibility of soft ground make it challenging for construction. Infrastructure on soils with inadequate load bearing capacity commonly require installation of deep foundation, for example deep piling which is not always economical or environmentally safe. Traditional mitigation measures have involved stabilizing native challenging soils with cement to improve its engineering performance. The use of cement poses threat to the environment due to high energy intensive manufacturing process and resulting high CO2 emissions are of concern, as is the slow progress towards exploiting renewable natural resources. The research will lead to innovative methodologies for environmentally sound soil stabilization on ground with soft soil deposits which generally exhibit poor engineering characteristics. Extensive and systematic experimental studies will be conducted to determine the applicability and feasibility of various stabilizing agents in soil mixing by assessing the mechanical properties of stabilized soils. Nanoparticles will be mixed with a number of soil stabilizers to effectively enhance the performance of native soils. The research will also reveal the impact of nanoparticles in the barriers of Canadian spent fuel storage systems leading the construction of advanced barriers with high performance. The advanced technology derived from the research will enhance soil strength permitting construction of safer bridges, high-rises and transportation systems in Canada. It will assist the Nuclear Waste Management Organization (NWMO) in its development of safe storage facilities for Canada's spent hazardous fuels. Technological achievements from the research will be used in application development through active collaboration with industry. The program will train engineers and scientists with expertise in novel techniques of soil stabilization and barrier materials enhancement.
