摘要：对比研究了单掺和复掺矿物掺合料（粉煤灰、超细矿粉、普通矿粉）对高性能混凝土（HPC）工作性、力学性能和早期抗裂性能的影响。结果表明：当超细矿粉与粉煤灰以8∶2质量比复掺时，混凝土的工作性较好，28 d抗压强度最高，早期抗裂性能最好；单掺超细矿粉组试件的28 d抗折强度略均低于单掺普通矿粉组试件，矿粉与粉煤灰复掺组试件的28 d抗折强度略低于对应的单掺矿粉组试件；综合而言，相比超细矿粉与粉煤灰2∶8和5∶5的复掺比例，8∶2复掺时，HPC的综合性能最好。 Abstract: The effects of individual and compound mixing of mineral admixtures(fly ash, ultrafine mineral powder, and ordinary mineral powder) on the workability, mechanical properties, and early cracking resistance of high-performance concrete(HPC) were investigated comparatively. The results show that when ultrafine mineral powder and fly ash are mixed in the mass ratio of 8∶2, the concrete has the good workability, the highest 28 d compressive strength, and the greatest early cracking resistance. The 28 d flexural strength of specimen with ultrafine mineral powder alone is slightly lower than that of the specimen with ordinary mineral powder alone, and the 28 d flexural strength of specimen with composite addition of mineral powder and fly ash is slightly lower than that of specimen with mineral powder alone. Overall, compared to the compounding ratios of 2∶8 and 5∶5 for ultrafine mineral powder and fly ash, when the compounding ratio is 8∶2, HPC exhibits the best comprehensive performance.

The 28 d flexural strength of specimen with ultrafine mineral powder alone is slightly lower than that of the specimen with ordinary mineral powder alone, and the 28 d flexural strength of specimen with composite addition of mineral powder and fly ash is slightly lower than that of specimen with mineral powder alone.
