Early age aggregation mechanisms of alkali-activated slag particles

The research belongs to the field of soft matter and cementitious materials, specifically the early-age aggregation of alkali-activated slag (AAS) particles. The data combine four techniques: multispeckle diffusing wave spectroscopy (MSDWS: normalized intensity correlation functions g2, relaxation-time distributions P(τ), fast/slow relaxation times τ and amplitudes A); small-amplitude oscillatory shear (SAOS: storage modulus G′ with standard deviations); in situ X-ray powder diffraction (XRPD, Cu Kα: intensity vs. 2θ and vs. scattering vector q, and normalized low-angle intensity vs. time); and particle size distribution.

Datasets labelled "CCPCE" and "noCCPCE" refer to pastes mixed with the CaCl₂ + PCE solution and with distilled water, respectively. Sample preparation and measurement protocols are described in the Materials and methods section of the article.
