Admixture effects on the rheological/mechanical behavior and micro-structure evolution of alkali-activated slag backfills
(MDPI, 2023)Recently, alkali-activated slag (AAS) has attracted extensive attention in cemented paste backfill (CPB) due to its low cost/CO2 emissions and high strength benefits. However, a comprehensive analysis of the mechanical/rheological ... -
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 ... -
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 ... -
A New index and control method of filling effect for cemented paste backfill in coal mines
(Taylor & Francis Ltd., 2023)The scientific filling effect characterization is very important for backfill mining. A new filling effect index, the final backfill ratio (FBR), is proposed through experimental tests and theoretical analysis, and the ... -
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 ... -
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 ... -
Study of early-age performance of cementitious backfills with alkali activated slag under internal sulfate attack
(Elsevier, 2023)The vulnerability to internal sulfate attack of calcium-rich ordinary Portland cement (OPC) and its relative high cost force mines to explore technically effective and low cost alternative binders to solidify sulfate-containing ...
