Foamed concrete has been widely used in tunnels where foamed concrete-rock joints are usually encountered. However, few studies have been conducted on the mechanical properties of the joint. To investigate the shear behaviors of the joint, compressive properties of foamed concrete were first studied ...

1. Ensure the apparatus and associated equipment are clean before test and free from hardened concrete and superfluous water. 2. Weigh the bottom cylinder to nearest 10gm , put it back on the stand and cover it up with a pair of floats. 发表人:马来西亚留学生 李航宇 3. Gently fill the...
aThe results of the laboratory tests considered in this paper show a number of possible methods of using fly ash to optimize the chloride resistance of concrete. Table 4 summarizes advantages that can potentially be achieved,assuming the use of typical structural concrete. 在这个纸展示考虑的实验室...
On the other hand, when the thickness of the coral mud surface layer is too thin, it is susceptible to be influenced by the autoclaved aerated concrete block wall and block joints. Therefore, a surface layer thickness of 10 mm is optimal compared to 5 mm and 20 mm, as it ...
The objective of the work was to perform laboratory testing and evaluation of the grouted coupler connection details utilized on precast concrete elements for the Keg Creek Bridge. The Bridge Engineering Center (BEC), with the assistance of the Iowa Department of Transportation (DOT) Office of ...
