Composition of Paste-like Backfill Material Paste-like backfill material mainly includes cementitious material and aggregate.
Cementitious materials select paste-like cementitious material.
The choose of aggregate should adapt to local conditions, turn the waste into profit and select cheap or waste materials to meet the premise requirements of backfill for reducing the filling cost.
