In this study thermal conductivity increase of mortar or concrete plates due to embedded cylinder metal elements perpendicular to the slab surface is evaluated, through a numerical investigation. Correlations with a general effectiveness have been found, and validated through an experimental investigation....
In Auckland,polished concrete flooringtypically ranges from NZD$70 to NZD$210 per square metre, depending on the finish and complexity. This price encompasses the grinding of the concrete slab, thepolishing process, and any desired decorative treatments. These treatments can include adding aggregates,...
In building energetic calculations, thermal conductivity values from EN ISO 10456:2008 [1] are mainly used, although the standard define concretes values only by taking into account the density and the approximate percentage of reinforcement. Details of the structure type (column or slab), ...
Thermal insulation structure of building and its construction method Provided is a heat insulating structure of a building and a construction method thereof. A heat insulating structure for a building 1 includes a concrete floor slab 10, a concrete outer wall portion 20 standing on the floor slab...

Due to one sided heating and the low conductivity of concrete, a thermal gradient will appear over the slab thickness. Consequently, the outer concrete layers will expand more than the inner layers, which will result in a thermal curvature towards the fire. At the column-slab connection, these...
To test the model, the evolution of the temperature inside a two-dimensional slab due to heat flux from one boundary to the opposite one is computed and compared to analytical solutions, see Fig. 7. Two distinct configurations are employed, one representing a regular particle pattern comprising ...
The structure was set on a sand-gravel pillow and rigid concrete slab, and its settlement was periodically measured at five measuring points along the ... Tomasz Ferenc,Rafa Gierasimczyk,Tomasz Mikulski - Polish Maritime Research 被引量: 0发表: 2024年 多孔路面材料与厚度对地表径流的净化效能 To...
resulting in a perpetually saturated slab. This saturation significantly enhanced the thermal conductivity of the slab, leading to a rapid and relatively uniform heat flow from the top to the bottom. Consequently, the temperature gap between the upper and lower portions of the slab diminished, as ...
Examples include a slab on grade, a walkway, a low-height retaining wall, etc. All other applications belong to structural concrete where some type of reinforcement is used. It would be unsafe, for example, to use a nonreinforced concrete beam to sustain any external load including its own ...
