Abstract This wrok aims at the problems of various evaluation methods and weak universality in quantifying morphological characteristics of slurry-modified recycled aggregates. By obtaining 8 different morphological parameters through 3D scanning technology and 2D image processing technology, the morphological characteristics evaluation method of slurry-modified recycled aggregates was investigated that used 3 slurries of alkali-activated materials and 4 ranges of particle diameter. The study shows that the morphological parameters of the slurry-modified recycled aggregates show a skewed distribution, and they can be expressed as mean values when the number of samples is large enough. The correlation analysis shows that 8 morphological parameters contain certain overlapping information. It brings some negative influences in the evaluation of the morphological, angular and textural characteristics of recycled aggregates. By wiping off the overlapping information of morphological parameters, the variables with complex correlations are reduced dimensionality to transform into comprehensive indexes, which are textural factor F₁, morp-hological factor F₂, and angular factor F₃. According to the score analysis of these comprehensive factors, the morphological changes of the recycled aggregates after slurry modification with different alkali-activated materials have the same trend. Compared with the raw recycled aggregate, the slurry-modified recycled aggregates have lower surface roughness, less angular and near-spherical morphology. These comprehensive factors bring more efficient morphology evaluation and better guidance for practical engineering applications of slurry-modified recycled aggregates.

Key words： recycled aggregate alkali-activated material slurry-modified morphological characteristics morphological parameter factor ana-lysis
