Granite is extensively used in the construction industry; however, substantial solid waste is produced during production. This study focused on the feasibility of replacing cement with granite powder (GP) in cement mortar by investigating various properties, like consistency, water retention, density, setting time, compressive strength, and flexural ...

Research on the design method of flexural capacity of RC beams strengthen by ultra-high-performance concrete [PDF]
Due to the increase in traffic volume, load level, and service life of existing bridges, the bending bearing capacity of reinforced concrete beams (hereinafter referred to as RC beams) has decreased, leading to safety issues.

Abstract This study presents an in‐depth investigation of a cold‐formed steel portal frame structure, originally designed in the 1950s, through advanced nonlinear analysis. The research aims to compare traditional structural modelling approaches with more detailed nonlinear modelling techniques while evaluating various retrofitting strategies.

Finite Element Modeling of the Transition Zone between Aggregat and Mortar in Concrete [PDF]
Visual observations to the Interfacial Transition Zone (ITZ) between aggregate and mortar in concrete showed that this area differs significantly to the bulk mortar, further away from the ITZ.

Abstract This study investigates the impact of magnetic alignment of micro steel fibers (0.35%, 0.70%, and 1.05% contents) on the mechanical and electrical properties of fiber‐reinforced self‐compacting concrete. A simplified magnetic circuit was designed and built to align the fibers within the concrete matrix.
