| 摘 要： | 试验研究了胶凝材料类型、料浆浓度和凝石含量对似膏体充填体早期强度的影响,结果表明:凝石作胶凝材料的充填体强度高于以普通水泥作胶凝材料的充填体强度;似膏体充填体的8 h强度随料浆浓度和凝石含量的增加呈近似线性增加;料浆浓度和凝石含量对似膏体充填体的8 h强度具有近似相等的贡献。

| Abstract: | Study was made by experiments on the influence of cementitious material's type,the density of slurry and the content of sialite on the early strength of paste-like backfill material.The results showed that strength of backfill material with sialite as cementitious material is higher than that of backfill material with ordinary portland cement as cementitious material;8-hour strength of paste-like backfill material varies approximately linearly with both density of slurry and content of sialite;the density o... |
