The effect of alkali content (% K2O + %Na2O) on the mechanical properties of alkali activated blast furnace paste has been investigated. The paper presents the study on workability, compressive strength, split tensile strength and microstructure of alkali activated blast furnace slag paste specimens prepared by using of sodium silicate and potassium hydroxide solution as activators. The experim...

The cement industry is facing the challenge of a lack supplementary cementitious materials substituting clinker. This applies primarily to granulated blast furnace slag, most commonly used as main component cements, due changes in metallurgical industry, and siliceous fly ash abandonment fossil fuels world. A potential new common cements may be calcined marls, which are available large quantiti...

The Clean Coal Technology (CCT) Demonstration Program is a government and industry co-funded effort to demonstrate a new generation of innovative coal utilization processes in a series of " showcase " facilities built across the country. These projects are carried out on a sufficiently large scale to prove commercial worthiness and generate data for design, construction, operation, and technica...

Abstract Partly replacing Portland cement (PC) with lower carbon footprint cementitious materials such as ground granulated blast furnace slag (slag) is considered a practical method for reducing CO 2 emissions in the concrete industry. To mitigate slow reactivity of system and enhance early-age strength, addition chemical activator solution. However, effect on creep behaviour slag-blended conc...

Six supplementary cementitious materials (SCMs) were identified to be incorporated in concrete exposed high-temperature cycling conditions within the thermal energy storage literature. The selected SCMs are bauxite, chamotte, ground granulated blast furnace slag, iron silicate, silica fume, and steel slag. A microstructural characterization was carried out through an optical microscope, X-ray d...

EPA has completed a substantial study to re-evaluate use of the presence of slag wool fibers as a potential marker for World Trade Center (WTC)-derived dust contamination. Slag wool is an insulating material (made from blast furnace slag) that was used in the construction of the WTC. Large quantities of slag wool were released into lower Manhattan by the collapse of the WTC. Samples of dust col...

Industrial waste materials are increasingly being used in asphalt to improve pavement quality and reduce environmental impacts. The aim of this research was test the distress-related effects using ground-granulated blast-furnace slag (GGBFS) as a filler hot mix asphalt. There is potential for GGBFS be integrated into Western Australian (WA) pavements. replacement conventional hydrated lime (HL)...
