This study aims to determine the concentration of particulate matter (PM) produced from construction sites focusing on concrete and masonry works in terms of the fractions of total suspended particles (TSP) and Particulate Matter 10 μm (PM10) and their chemical elements. The experimental study was...
Anchoring hook for tying masonry to concrete works - includes bent end housed in groove in concrete to give firm connectionThe twisted or deformed round steel ties are bent to a particular pattern and are enforced in a groove in the concrete work. A 90 deg. rotation blocks the tie in the...
The experimental work was carried out in two separate stages. In the initial stage, we applied the fractal analysis approach to the data provided in a number of previous works available in literature in order to give the intended results a credible basis. Regarding these experimental investigations...

By incorporating design principles similar to those of unreinforced masonry, 3DCP allows the use of concrete solely in compression, thereby minimizing the need for steel and making the structures more convenient to reuse and recycle. The building and construction sector consume 33–38% of the world...
Several countries and standard regulations limited the use of the recycled fine aggregate fraction to mortars intended for masonry and rendering works, non-aggressive environments, or low-strength concrete used in non-structural applications [41,42]. Nowadays, the recycled fine aggregate fraction is ...
Masonry mortars, precast concrete and masonry units with different ratios of coal bottom ash replacing conventional aggregates have been studied. With the incorporation of coal bottom ash in the mortars, the workability, density and strength decrease whereas the porosity, the weight loss and the ...
Displacement incompatibility for RC frame structures is a well-known issue in seismic engineering and it has been investigated in past research works. However, these works mainly focused on the seismic displacement incompatibility between structural components (e.g., the “beam elongation”, Fenwick an...
The dovetail profiled steel sheets (DPSs) not only can provide both permanent formworks, but also function as reinforcement of composite walls [1], [2]. What is more, the dovetailed ribs embedded in concrete have a strong interlocking effect between steel sheets and concrete, and the ...
