英文摘要： According to the demand of current national sustainable development strategy, the preparation technology and early mechanical properties of geopolymer concrete under the application background of the rapid repair and construction engineering after disasters such as earthquakes, landslides and terrorist attacks are studied through experiment and theoretical research. The key technical problems such as the raw material choice，proportioning design and preparation technology in the process of preparation of geopolymer concrete are breakthrough. The change law of the early mechanical characteristics of geopolymer concrete is investigated.Further more, the reaction mechanism of geopolymer and the strength formating mechanism of geopolymer concrete is revealed. As a result,a complete preparation technology system and the theory system of the change law of the early mechanical properties of geopolymer concrete are set up, which can solve the technology and theoretical problems that limit the large production and spread application of geoplymer concrete.Finally, it can provide important theoretical basis and technical support for geological polymer concrete application in the field of repair and construct engineering.
