Adding large-size demolished concrete lumps (DCLs) into the core of concrete-filled steel tubes (CFTs), a proposal by the authors and co-workers, has been demonstrated to be a practicable alternative means for old concrete recycling.
The Proserpina Dam, 12 metres (40 feet) high, features a masonry-faced core wall of concrete backed by earth that is strengthened by buttresses supporting the downstream face.
Zuiderpoort is a modern three-storey office building, with movable walls (layered drywalls) around a core consisting of concrete walls (Table 1).
For all three concretes, moisture measurements showed that the core of the concrete beams was not saturated, indicating self-desiccation and low pore connectivity.
The city council decided immediately to rebuild it around a core of reinforced concrete, and the work was completed by 1912.
Between Eliasson's light and Artec's sound comes the architecture of Henning Larsen Architects, and a core of dark concrete the colour of Iceland's lava fields, that acts as a foil for one and a container for the other.
The Bullitt Foundation challenged a design firm, the Miller Hull Partnership, and their collaborators to develop a core of steel, concrete and timbers with a life expectancy of 250 years, a nearly unheard-of number in an industry that typically uses 40-year life spans in appraising the value of commercial buildings.
Between 1968 and 1971 its facing stone was dismantled and shipped across the Atlantic Ocean to the U.S. state of Arizona, where it was reerected on a five-span core of reinforced concrete to serve as a tourist attraction at the resort town of Lake Havasu City.
Test parameters included the strength of steel flanges, strength of core concrete, and filling of core concrete.
This implies that a higher curing temperature produces a higher temperature rise in concrete but leads to a lower differential between the core and surface of concrete element.
