“…19). The crushing process is likely to generate damage in RC aggregates and concretes with RC aggregates have more ITZ [78]. From these points of view the evolution of E TSTM of 30RS-0RG concrete is not obvious.…”

There is a constant drive for the development of ultra-high-performance concrete using modern green engineering technologies. These concretes have to exhibit enhanced durability and incorporate energy-saving and environment-friendly functions. The object of this work was to develop a green concrete with an improved sulfate resistance. In this new type of concrete, recycled aggregates from construction and demolition (C&D) waste were used as coarse aggregates, and granulated blast furnace slag (GGBS) and fly ash-based geopolymer were used to totally replace the cement in concrete. This study focused on the sulfate resistance of this geopolymer recycled aggregate concrete (GRAC). A series of measurements including compression, X-ray diffraction (XRD), and scanning electron microscopy (SEM) tests were conducted to investigate the physical properties and hydration mechanisms of the GRAC after different exposure cycles in a sulfate environment. The results indicate that the GRAC with a higher content of GGBS had a lower mass loss and a higher residual compressive strength after the sulfate exposure. The proposed GRACs, showing an excellent sulfate resistance, can be used in construction projects in sulfate environments and hence can reduce the need for cement as well as the disposal of C&D wastes.

“…Hence, a more convenient method is needed to obtain the actual aggregate shapes. 3D laser scanning is another method used to scan and obtain 3D aggregate shapes (Kim et al 2003;Lanaro and Tolppanen 2002;Mazzucco et al 2018). However, these 3D laser scanners are comparatively slower than the structured light scanners (Laga et al 2019).…”

Mesoscale numerical modelling is an effective method of representing concrete as a three-phase material. Accurate aggregate geometry representation is an important aspect in numerical mesoscale modelling of concrete to predict mechanical properties as well as the damage initiation and fracture propagation. In this paper, a novel approach of 3D scanning of aggregates P.S.M Thilakarathna would like to thank The University of Melbourne, Australia for providing Melbourne Graduate Research Scholarship Award.
