Wastes of Glass are recognized as pozzolanic material. This study aims to investigate utilization local glass wastes in Sudan supplementary cementitious materials. Two specimens having different colors procured from a source namely Sudanese Emirati and Metal Company (SEGMAL). Then thy ground micro sizes producing two types powders, clear white powder (W-GP) colored (C-GP). The Specimens charact...

844 Concrete is one of the most important construction materials. However, it is not so compatible with the demands of sustainable development because manufacturing of cement generates a large amount of carbon dioxide and therefore cement consumption produces a huge carbon footprint. Currently, the cement consumption is generally lowered by adding supplementary cementitious materials to replace...

Despite reported synergies between alumina rich supplementary cementitious materials (SCMs) and limestone, previous studies have focused on up to 5% limestone content. Slag hydration in the presence of 10% limestone is reported in this paper. Hydration was followed through chemical shrinkage, calorimetry, thermal analysis, electron microscopy and X-ray powder diffraction. The results show that ...

The development of printers and materials for 3D Printing Construction during the last two decades has allowed construction increasingly complex projects. Some them have broken speed records due to simplification process, particularly in non-standard geometries. However, performance security reasons used had considerable amounts Portland cement (PC), a constituent that increases cost environmen...

This research investigated the possibility of using metallurgical slags from copper and lead industries as partial replacement for cement. The studied were fayalitic, having a mainly ferro-silicate composition with minor contents Al2O3 CaO. treated at 1200–1300 °C (to reduce heavy metal content) then granulated in water to promote formation reactive phases. A full hydration study was carried ou...
