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。
Using fly ash to replace part of the metakaolin, the optimum polymer matrix mix ratio was sought using strength as an indicator. In the three conservation systems of standard maintenance, steam curing, and pressure steaming and curing, the most suitable curing process for cementitious materials is selected; then three steel fibers are added to the optimal matrix, and the optimal maintenance process is selected. A series of strength fiber-reinforced polymer-based reactive powder concrete (RPC) was obtained with a compressive strength of up to 55.2 MPa and a bending strength of 22.44 MPa. The results of its study on chloride ion penetration resistance and carbonation resistance show that the geopolymer-based RPC has very excellent durability.
