The aim of this paper is to numerically investigate the effect of size distribution and shape of elastic inclusions on the long-term creep of concrete. Several microstructures with prescribed size distribution and spherical or polyhedral shape of inclusions are generated. By using the 3D numerical ...
The characteristics of aggregate have a great influence on the performance of fresh and hardened concrete, including porosity, grading or size distribution, moisture absorption, shape and surface texture, crushing strength, elastic modulus, and the type and content of deleterious substances. These ...
which constitutes 35–40% of global waste. It explores the potential use of recycled fine aggregates (RFA) from concrete demolition waste as a sustainable alternative to natural fine aggregates in 3D printed mortar (3DPM). By conducting a systematic literature review (SLR) and utilizing VOS...
It should be noted, however, that fine aggregate has the same properties as the old concrete structure that it came from [33–35]. Therefore, actions should be taken in order to find applications for this material. Moreover, due to the rapid growth of industry, there is a need to build...

The shape of the aggregate affects the embedded structure between the aggregates, thus affecting the performance of asphalt concrete. In this study, extreme gradient boosting (XGBoost) classification is used to study the automatic shape classification of aggregates. The expression of main and ...
The properties of coarse aggregates have a great influence on the mechanical characteristics of porous asphalt concrete (PAC). The objective of this study is to reveal the influence of coarse aggregate morphology on the skeleton mechanical characteristics of PAC-13. To achieve this goal, a ...
morphologyhydrationEnvironmental degradation is a major challenge in the developing countries, which are caused due to unmanaged solid waste, or improper disposal. This study investigates the effect of using silica mineral waste (eco sand) as aggregate in a green high strength concrete, in which ...
Normally, a backscattered electron (BSE) image of a polished cross-section through a concrete sample is used to obtain information about the microscopic morphology of concrete [21], [22], [23], [24]. Then, successive strips based on a concentric expansion method near the aggregate are ...
CBA can be used as a fine aggregate replacement in concrete due to its appearance and particle size distribution, comparable to river sand [70,96,125]. CBA particles are often angular, highly irregular in shape, and visibly porous, having a rough, gritty surface texture and interlocking ...
