Composite material used for deep-hole grouting
The invention provides a composite material used for deep-hole grouting. The composite material comprises, by weight, 15% to 60% of cement, 35% to 80% of fly ash and 5% to 10% of clay. According to the invention, a grouting fluid is prepared by mixing cement, fly ash, clay and water; complete isolation time is improved to 30 to 32; fluidity of the composite material is reduced to 30 to 28; thus, deep-hole grouting effect is improved.
