Measuring the in-situ compressive strength of concrete in final structures is an essential but challenging process. Coring combined with non-destructive rebound hammer measurements provides the most ...

Material stress–strain properties are required in the nonlinear analyses of structures. Stress–strain relationships for some construction materials such as concrete and steel are available in the ...

Ettringite-based expansive agents effectively improve the performance of heat-cured self-compacting concrete, offering a cost ...

Hollow Glass Microspheres are inorganic, nonmetallic spherical materials created by specific processes, commonly with diameters in the range of 10 to 250 μm and wall thicknesses of 1 to 2 μm (Figure 1 ...

Incorporating 2.5 % scrap aluminum engine residue in foamed concrete significantly boosts compressive strength and thermal ...

President, Wyoming Test Fixtures Inc. When used for material comparisons, notched testing is typically performed using a quasi-isotropic composite laminate, consisting of equal numbers of 0°, 45°, ...

One of the challenges confronting oil and gas operators — especially those working in areas with low fracture gradients or weak formations such as the Delaware, Anadarko and Permian Basins — is ...

Inspired by oriented and Bouligand structures in natural organisms with remarkable strength and toughness, this study aims to ...

Los Angeles could have to rebuild over 30% of the city. California has fires, earthquakes, high winds and other risks. Replacing hundreds of billions in residential and commercial buildings and roads ...
