On pumping ultra-early strength concrete of artificial sand

摘要：

　　With the gob-side entry retaining technology in coal mining project,the materials research of backfill for mine gateway side and development to become the focus of attention.This study is based on the need of Faer coal mine to adopt P42.5 portland cement,Tz-1 early strength agent,Tj-1 super plasticizer,prepared from 8 hours to form removal,16 hours strength of up to 7.9MPa,24 hours strength of 19MPa,3 day strength to 37MPa,and the construction of super-excellent early strength pumping artificial sand concrete,and obtained satisfactory results through engineering.
