干法脱硫粉煤灰路用性能的试验研究

摘要

展开了干法脱硫粉煤灰路用性能的试验研究.结果表明:干法脱硫粉煤灰与石灰的配伍性差,而与水泥的配伍性良好;以水泥、干法脱硫粉煤灰为胶结料的稳定碎石具有足够的力学强度和水稳定性,可满足公路基层的要求,且施工性良好,拌和后8h内碾压成型几乎不影响其力学强度.%Experimental research on road performance of dry-desulphurized fly ash had been done. Results show that dry-desulphurized fly ash has poor compatibility with lime but has good compatibility with cement. Stabilized crush stone used cement and dry-desulphurized fly ash as binder material has enough mechanical strength and water stability to meet the requirement of road base course. It almost has no influence on its strength when rolled in 8 h after mixing and it is good for practical application.
