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,选用最优养护工艺,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。 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.
