| 摘 要： | 利用粉煤灰取代部分偏高岭土，以强度为指标寻求最佳地聚合物基体配合比，在标准养护，蒸汽养护，压蒸养护三种养护制度中，选出最有利于发挥胶凝材料活性的养护工艺，然后在最佳基体中掺入三种钢纤维，选用最佳养护工艺，可得到一系列强度的纤维增强地聚合物基活性粉末混凝土（RPC），其抗压强度最高达55.2MPa，弯拉强度达22.44MPa，对其抗氯离子渗透和抗碳化性能进行的研究结果表明，地聚合物基RPC具有非常优异的耐久性。

| Abstract: | Having portion of kaolin clay replaced with fly ash,search most optimum ratio of geopolymer to prepare geopolymer-based reactive powder concrete.In order to select a curing technology which may be helpful to develop the activity of gelling substances,three cur ing systems are compared with each other of the standard one,steam one and pressure-steam one.After that three sorts of steel fiber are mixed into selected batch and then a series of steel fiber reinforced geopoly mer-based reactive powder concrte(RPC)are obtained of different strength.The compressive and bending strength are respectively as high as55.2MPa and22.44MPa.A fur ther test indicates geopolymer-based reactive powder concrete has excellent durability. |
