Dr Lei Wang, ... Dr Daniel C.W. Tsang, in Sustainable Remediation of Contaminated Soil and Groundwater, 2020 3.2.1 Blast furnace slag-based AAC. Blast furnace slag is a calcium-silicate-based product removed from the top of molten iron during its extraction from ore in a blast furnace. Usually, it is rapidly cooled to a glassy state and ground for use in construction …
The slag viscosity is important because (i) it affects the lubrication supplied to the mold (1/η ), (ii) the SEN erosion rate is proportional to (1/ η ), and (iii) high-viscosity fluxes are used to minimize slag entrapment although at the expense of the powder consumption [ 3 ].

Slag-based materials including mortars, concretes, Ca-geopolymers, etc., are known to display a fascinating blue/green color upon hydration. This specific color is of particular concern in applications where visual esthetics are important. Yet only limited studies have been devoted to this phenomenon so far and its origin remains unexplained.
Slag, as the term will be used here, is any siliceous melt that arises in significant quantity from the various processes used in the production of iron and steel, and more particularly the solid materials that forms when such melts cool. Slag from the production of ferrochrome is also included here; this material is produced in substantial ...

The slag blended cement mortars were prepared according to GB/T 17671, and the mix proportion is shown in Table 2.After mixing, the fresh mortars were cast into molds with sizes of 25 × 25 × 280 mm 3 and 40 × 40 × 160 mm 3 and then sealed with plastic film. For standard-cured mortars, the samples were demolded at 1 d age and then cured for 28 d in saturated …
