Morphogenesis in solidification phases of lightweight concrete surface at early ages

- Morphogeneses of lightweight concrete surfaces at early ages solidification have been presented.
- The measured concrete surface morphologies are compared at different stages.
- Portable 3D LASER scanning technique to determine transitional stages has been used.
- 3D isometric images, surface isotropy and amplitude surface morphological parameters are discussed.
- Four significant transitional phases, which take place during solidification, are elucidated.

The article is devoted to the identification of the morphological evolution of the surface of lightweight concrete (LWC) at early ages. In order to better understand the complex process of solidification, the measured morphologies are compared at different stages. The presented research demonstrates the capability of the portable 3D (LASER) scanning technique to determine four transitional stages during the early age morphogenesis of a LWC surface. The most significant results, in the form of 3D isometric images, areal directionally depended morphology and amplitude surface morphological parameters, are discussed. Four significant transitional phases, which take place during solidification, are elucidated.
