Alkali activated slag shows considerable promise as an environmentally friendly alternative to binders produced from ordinary portland cement. The shrinkage behavior of alkali activated slags, however, is not well understood, and is a hurdle to widespread adoption. The use of pre-wetted lightweight aggregate-based internal curing to mitigate shrinkage in slags …

The results show that the n-C-S-H-PCE has a pronounced enhancement effect on the mechanical properties up to 7 d. The early strength enhancement of the n-C-S-H-PCE can reach 64% at 1 d. Due to the fast hydration, the autogenous shrinkage is higher in the concrete containing n-C-S-H-PCE. And the slag powder also increases the autogenous shrinkage.

One factor limiting alkali activated slag binders is shrinkage, which is both more substantial in alkali activated slag than in OPC and less well understood [35]. Shrinkage can take two forms: drying shrinkage, where water leaves the system through evaporative processes, or autogenous shrinkage, which does not involve water exiting the system.

In another preferred embodiment, the initial grinding of the slag is carried out as a semi-autogenous grinding operation and leads to a fairly coarse pulp although suitable for flotation in a unit cell with an appropriate frother and collector. Typically, the grinding proceeds until about 80% of the pulp passes a 100 mesh screen.
