Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.This study investigates the mechanical and physical properties of mortars incorporating crushed hazelnut shell (HS) as a partial replacement for fine aggregates. Mortar mixtures were prepared with varying water‐to‐cement (w/c) ratios ranging from 0.35 to 0.50 and HS dosages of 2.5%, 5%, and 7.5% by weight, along with reference mixtures without HS.

Control of Concrete Segregation and Quality Enhancement Using Continuous Mixer Units
Advances in Civil Engineering, Volume 2025, Issue 1, 2025.Managing concrete segregation during transportation and pouring at construction sites is posed as a substantial challenge. The utilization of continuous mixer units to address segregation and enhance the quality of concrete is discussed in this paper. These mixer units were tested in both horizontal (M–Y mixer) and vertical (ESG mixer) setups.
