通过对比不同比例的石粉取代比例,对净浆、新拌混凝土的工作性能及硬化混凝土的强度、碳化深度及抗渗性能的影响。结果表明,随着石粉取代比例的增加净浆流动度变大,标准稠度用水量增加;而随着石粉的增加混凝土的工作性有所下降,抗压强度有所下降,抗渗性能及抗裂性能随石粉量的增加而变差,对碳化性能无明显影响。 By comparing the proportion of different proportions of the replacement of stone powder on the performance of fresh concrete, fresh concrete performance and hardened concrete strength, carbonation depth and impermeability. The results show that with the increase of the replacement ratio of the stone powder, the flowability of the grout becomes larger and the water consumption of the standard consistency increases. With the increase of the stone powder, the workability of the concrete decreases, the compressive strength decreases, the impermeability and crack resistance Performance with the increase in the amount of stone powder deterioration, no significant effect on the carbonization performance.
