The Research and Application of Pumping Ultra-Early Strength Concrete
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 Jining well to adopt 42.5R portland cement, Tj-1 early strength agent, Tj-1 super plasticizer, prepared from 8 hours to form removal, 16 hours strength of up to 6.2MPa, 24 hours strength of 12MPa, 28 day strength to 43MPa, and the construction of super-excellent early strength pumping concrete, and obtained satisfactory results through engineering.
