| dc.description.abstract | In order to adopt geopolymer concrete as a pavement repair material due to its better durability, splitting and slant shear tests are performed. Effect of curing time, degradation of the pavement concrete under different acid conditions on the bond strength of geopolymer with conventional concrete, and comparison of the metakaolin geopolymer with other pavement repair materials are analyzed. It was found curing time affects the interface bond strength greatly and the interface bond strength degrades quickly in an acid environment. Effect of molar ratio of SiO2/Na2O, calcium aluminate cement, and slag on early strength of the geopolymer have been studied. It was found molar ratio of SiO2/Na2O of 1.0 gave the highest early strength in 24 hours. Also, freeze-thaw durability of geopolymer concrete are investigated by exposing the specimens to rapid freeze-thaw cycles. Based on these research results, adopting metakaolin geopolymer in accelerated PCC pavement repairs is a feasible option. | en_US |
