Data for: IMPACT OF FIELD CONDITIONS ON THE STRENGTH DEVELOPMENT OF A GEOPOLYMER STABILIZED MARINE CLAY

In this research, Fly Ash (FA) and Slag (S) based geopolymers, prepared with various fly ash and slag contents, were used as cementitious materials to stabilize a soft marine clay for usage in ground improvement applications. The effect of a number of preparation and curing factors, which occur in practice such as mixing method and time, water content and curing temperature and time, on strength development and changes in the microstructure of the clay stabilized with FA+S based geopolymers was studied. The properties of FA and S based geopolymers when used as a cementitious stabilizer to stabilize soft soils need to be fully investigated before practitioners, industry and end-users are willing to consider them in sustainable applications. Hence the study of preparation and curing regime of FA and S based geopolymers in this research is novel and significant and will open new doors for the utilization of geopolymers in the ground improvement of soft marine soils. The data, provided here, are the results of tests conducted for this study.本研究中，以不同粉煤灰（Fly Ash, FA）和矿渣（Slag, S）掺量制备的粉煤灰-矿渣基地质聚合物（geopolymers）作为胶凝材料，用于加固软海相黏土以应用于地基加固工程。本研究探讨了实际工程中常见的多项制备与养护参数——包括搅拌方式与时长、含水率、养护温度与时长——对粉煤灰-矿渣基地质聚合物加固软海相黏土的强度发展规律及微观结构演变的影响。在工程从业者、行业主体及终端用户愿意将地质聚合物应用于可持续工程场景前，需对其作为软土胶凝稳定剂的各项性能开展全面研究。因此，本研究针对粉煤灰-矿渣基地质聚合物的制备与养护制度开展的探索具有创新性与重要意义，将为地质聚合物在软海相黏土地基加固领域的应用开辟全新路径。本文所提供的数据，即为本研究相关试验的测试结果。
