Research on the strength prediction model of Na based bentonite filling body based on ultrasonic transverse wave testing

As the core unit of backfill mining method, the strength of backfill is an important indicator to ensure safe mining. Na-based bentonite features a high methylene blue adsorption capacity and green compressive strength, making it a high-quality additive for preparing filling materials. However, ther...
