Cement kiln dust (CKD) is a by-product of cement production, which has the shortcomings low utilization and high-temperature activation. This study combined CKD slag as precursors for preparing pastes through quicklime activation under ambient conditions. The effects content on workability (flowability setting time), macro-mechanical properties, micro-structure CKD-slag binders were analyzed. experimental results showed that rapid precipitation Ca2+, Si4+, Al3+ ions from provided more...
The 718 steel used for plastic dies is required to be prehardened 29 – 35HRC. For large sized blocks, it relatively difficult additionally guarantee uniform hardness with the greatest difference of 3HRC and without any quenching cracks after heat treatment. In this paper, transient temperature field microstructure transformation during process blocks have been simulated numerically. Based on simulation experimental results, an appropriate process, that is, direct air cooled austenitising at...
To address the low utilization rate and environmental pollution of mine tailings (MT) cement kiln dust (CKD), a CKD-based cemented paste backfill (CPB) material was prepared using quicklime (CaO) sulfate (DH-7) as composite alkaline activator (CAA), with CKD slag cementitious MT aggregate. The optimal dosage new CAA determined through unconfined compressive strength (UCS) analysis. reaction products, pore structure, cation dissolution ability CPB activated by were investigated, analyzing...
