smelting of hammerable iron and its treatment in antiquity and Medieval produced also by-product: slag. Because of small yields of iron the process produced only small amounts of slag that did not attract attention of smelters concerning its possible use. the use of slag pieces was only accidental. a lot of slag pieces and blocks from slag pit shaft furnaces were used as a material for mound bu...

This paper investigates on the mechanical characteristics (compressibility and shear strength) of fly ash/ground-granulated blast-furnace slag (GGBS) mixtures at various mix ratios using consolidation direct tests, respectively. The studies were done a reduced duration load increment. compressibility behaviour has been found to improve with increase in GGBS content. Direct test results showed a...

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...
