冷再生材料抗冲刷性能分析

Analysis on the Anti-washout Performance of Cold Regeneration Material

为了研究冷再生材料的抗冲刷性能,在分析其形成机理的基础上,利用自制冲刷试验仪对冷再生材料进行抗冲刷性能的研究。试验数据表明,与二灰、水泥粉煤灰相比,水泥为再生剂的冷再生材料抗冲刷性能明显要好很多。冷再生材料抗冲刷性能主要与再生剂种类和配合比有关,在此基础上,提出了利用8min内材料的冲刷率作为冷再生材料抗冲刷性能指标。

In order to study the anti-washout performance of cold regeneration material, the author used a self-made washout test equipment to conduct the study based on its formation mechanism analysis. The experimental data indicated that the anti-washout performance of cold regeneration material used cement as the regenerant is significantly perfect than those used lime-fly ash and cement-fly ash, The anti-washout performance of cold regeneration material is related to the type of regenerant and mix design; this article suggested using washout ratio in 8min as the anti-washout performance index of cold regeneration material.
