A joint experiment and discussion for strength characteristics of cemented paste backfill considering curing conditions
(MDPI, 2022)
As lots of underground mines have been exploited in the past decades, many stope instability and surface subsidence problems are appeared in the underground mines, while the cemented paste backfill (CPB) technology has ...
Strength and microstructure evolution in cemented mine backfill with low and high pH pyritic tailings: Effect of mineral admixtures
(Elsevier, 2022)
To properly dispose mining-induced tailings, diverse techniques including cemented paste fill (CPB) have been already employed. Indeed, tailings are manufactured by using different admixtures which are poisonous to the ...
Characterization of early age behavior of cemented paste backfill through the magnitude and frequency spectrum of ultrasonic P-wave
(Elsevier Sci Ltd, 2020)
Cemented paste backfill (CPB) is broadly used for underground backfilling, improving the mechanical performance through the modification of its composition and, therefore, its microstructure and characteristics. in order ...
Effect of mineral admixtures on flow properties of fresh cemented paste backfill: Assessment of time dependency and thixotropy
(Elsevier, 2020)
Cemented paste backfill (CPB), an engineered mix consisting typically of tailings, cement and water, has become a regularly used structural material in most mines worldwide. the performance of the CPB structure is dependent ...
Rheological properties of cemented paste backfill with alkali-activated slag
(Mdpi, 2020)
This study investigates the time-dependent rheological behavior of cemented paste backfill (CPB) that contains alkali-activated slag (AAS) as a binder. Rheological measurements with the controlled shear strain method have ...
