摘要
针对LIFAC脱硫灰潜在的不稳定因素,从干缩率、雷氏夹值、浸水自由膨胀率以及与外加剂适应性几个方面展开其用于建材的稳定性研究。结果表明:LIFAC脱硫灰体系雷氏夹安定性良好;其浸水自由膨胀率与干缩率较基准水泥、粉煤灰偏大;与萘系减水剂相容性良好,但与木钙减水剂不相适应。
The stability and safety of LIFAC desulfuration ash for building materials from aspects such as dry shrinkage, Ray＇s folder value, free expansive ratio in water and compatibility with admixture were studied. The result showed it had nice Ray＇s folder value, higher free expansive ratio and dry shrinkage, compared with reference cement and fly ash, also good compatibility with naphthalene series water reducer, but not with calcium lignosulphonate.
