This work presents a novel way to examine the characteristics of fly ash, copper slag (CPS) along with addition Ultrafine Ground Granulated Blast Furnace Slag (UFGGBFS) based Geopolymer Concrete (GPC) for various molarities (10M, 12M and 14M). In GPC, ash was replaced UFGGBFS (5 %, 10 % 15 %) used as fine aggregate. Mechanical Characterization such split tensile, flexural strength, workability ...

In situ X-ray Micro-Tomography (XMT) analyses with a pixel size of 0.325 µm were conducted on slag-based blended cements containing 75% Ground-Granulated Blast-Furnace Slags (GGBS) and 25% Ordinary Portland Cement (OPC), or without CaCl2 acceleration. Results show the identification main cementitious phases need to perform data repeatability tests in order allow their quantification. Investigat...

Prevention and mitigation of acid rock drainage from mining are decisive for limiting environmental impact. Five by-products and industrial remnants (lime kiln dust, blast furnace slag, granulated blast furnace slag, cement kiln dust and fly ash) were investigated for their suitability to prevent acidity and metal(loid)s during leaching from highly sulfidic (50wt%, sulfide) waste rock in small ...
