硅粉在C80高强混凝土“多掺技术”中的研究

Study of silicon powder in high-strength concrete C80“more mixing technology”

研究了内掺硅粉、矿粉和粉煤灰对混凝土强度的影响;采用42.5普通硅酸盐水泥、中砂、5~25 mm碎石,掺入适量硅粉、矿粉、粉煤灰和缓凝高性能减水剂,可配制出C80高强混凝土.

This paper studies the influence of silicon powder,mineral powder and fly ash on the strength of concrete.The ordinary Portland cement 42.5,medium sand and gravels of 5to 25mm are used to mix with proper amount of silicon powder,mineral powder and fly ash gentle setting high performance water reducing agent,the high-strength concrete C80,is formulated.
