Although failure of material is not the only reason for bridge failures, it is a vital step for choosing the correct materials, the analysis of bridge design, and construction testing. Bridge members ...

AMES, Iowa – Grant Schmitz, eyes inches from a 6.5-by-12-foot panel of ultra-high performance concrete, studied the smooth surface for tiny cracks. He and other research engineers carefully marked ...

Results that are obtained from concrete specimens during laying of concrete may not actually represent the concrete strength in the structure. In situ NDT (non-destructive testing) at several ...

This prompted the researchers to test whether desert sand could be repurposed using a manufacturing approach that does not rely on conventional cement binding. During a series of trials, the ...

MIT scientists examined concrete samples from the archaeological site of Privernum, Italy (left) and mapped out the ingredients within (right). The red section is a calcium-rich lime clast. Courtesy ...

Laser scanning is a new and viable structural safety technique to detect the damaging effects of fire on concrete, new engineering research has found. Engineering research at The University of ...

1. Obtain a representative concrete sample from the revolving drum truck mixer. 2. Using a scoop, place concrete in the cylinder molds. For 6 by 12 inch molds, place in three equal layers (1/3 volume ...

Explore the future of construction with 3D concrete printing. Discover its viability for load-bearing components and ...

Cement production contributes an estimated 6% of global greenhouse-gas emissions, say scientists who are trying to chip away at the pollution problem. Two start-ups, one in Canada and another in ...
