As the coal remains the world's most abundant and accessible fossil fuel, the production of energy from coal will inevitably generate waste materials, i.e., the coal combustion products (CCPs). From 2002 to 2009, about 40% of CCPs was reused, while only 2.8% of the CCPs were used in pavement. This study intends to study the high volume reuse of fly ash, a major component of CCPs, in geotechnical engineering. The physicochemical properties and the microscopic imaging techniques are proposed as the tools to advance the knowledge of fly ash and fly ash-soil mixture. The outcome will provide the guideline for the beneficial reuse of the fly ash. The theories of the fine-grained materials behavior will be advanced, so that the chemical forces are comparable to that of physical ones. |
