摘要
采用控制变量法,研究了钢纤维长度与掺量对粉煤灰-矿渣基地质聚合物工作性及力学性能的影响。试验结果表明:钢纤维长度与掺量对地质聚合物的凝结时间影响不大,钢纤维长度及掺量增加,地质聚合物初始流动度下降;钢纤维对地质聚合物的抗压强度、抗折强度、折压比、等效弯曲强度、等效弯曲韧性具有明显的增强作用,且长钢纤维优于短钢纤维。
The effects of steel fiber length and dosage on the workability and mechanical properties of fly ash-slag based geopolymer were investigated using the controlled variable method.The experimental results showed that the length and dosage of steel fibers had little effect on the setting time of the geopolymer.The initial fluidity of the geopolymer gradually decreased as the length and the amount of steel fibers incorporated increases.Steel fibers had obvious enhancement effects on compressive strength,flexural strength,flexural-compression ratio of flexural strength to compressive strength,equivalent flexural strength,and equivalent flexural toughness of geopolymers,and long steel fibers were better than short steel fibers.
