摘要
研究对比了砖粉(BP)与粉煤灰(FA)对碱激发矿渣复合材料(AASC)力学性能的影响,结果发现:在15%和30%掺量下,BP-AASC与FA-AASC极限应力接近,但FA-AASC随掺量增加极限应变显著提升,而BP-AASC变化较小。经不同温度养护后,BP-AASC在150℃时性能最优,FA-AASC则在100℃最佳。结合单轴拉伸试验、DIC裂缝分析和SEM微观表征,揭示了掺料类型与温度对AASC材料拉伸性能的协同作用机制。
The effects of brick powder(BP)and fly ash(FA)on the mechanical properties of alkali-activated slag composites(AASC)were compared,and the results showed that the ultimate stress of BP-AASC and FA-AASC was close to that at 15%and 30%content,the ultimate strain of FA-AASC increased significantly with the increase of content,while the change of BP-AASC was small.After curing at different temperatures,BP-AASC had the best performance at 150˚C,and FA-AASC had the best per-formance at 100˚C.Combined with the uniaxial tensile test,DIC crack analysis,and SEM microscopic characterization,the synergistic mechanism of admixture type and temperature on the tensile properties of AASC materials was revealed.
