粉煤灰地聚合物在水泥混凝土路面修复中的应用研究

Application of Fly Ash Geopolymer in Cement Concrete Pavement Repair

为解决水泥混凝土路面修补材料存在的路面开放交通时间偏长和耐久性较差的问题,通过进一步实验、研究粉煤灰地聚合物混凝土制备、特性及机理,并将其应用于水泥混凝土路面的快速修补。实验后,粉煤灰地聚合物早期抗弯拉强度高,其力学强度、粘结强度均满足路面修补混凝土的技术要求,在路面快速修补材料中应用前景十分广阔。

To address the problems of a relatively long open transport time and poor durability for cement concrete pave-ment repair material,through further experiments,preparation,characteristics and mechanism of fly ash geopolymer con-crete,it was applied to the quick fix of cement concrete pavement.After the experiments,the anti-flexural-tensile strength of fly ash geopolymer was high at the early stage,and its mechanical strength and bond strength could both meet the tech-nology requirements of pavement mending concrete,which could have broad application prospects in the rapid repair materi-als of pavement.
