<p>To quantify the support provided by the shotcrete, flexural strength tests were conducted with two common, commercially available fiber-reinforced shotcrete (FRS) mixes using the round determinant panel (RDP) test method, ASTM C 1550. A portable RDP test ...

Researchers at National Institute for Occupational Safety and Health (NIOSH) are investigating how fiber-reinforced shotcrete mix designs can be extrapolated from proven designs employing wire mesh. This paper explains the results of round determinate panel ...

<p>Shikoku Electric Power Co., Inc. which is one of the famous Japanese electric power companies has developed the technology to manufacture the highly functional fly ash (HFA) which is a brand name &ldquo;Finash&rdquo; produced by sorting and classifying ...

<p>Adhesive mortar for tiles can be significantly improved by modification. Why should sprayed concrete not benefit similarly for various applications? This question has been investigated through large-scale tests in a tunnel cross passage, in an access gallery ...

There are several different driving forces behind the development of today’s modern robotic equipment. A need for efficiency, safety and economy. Most robotic units will help in this respect, by allowing substantially higher shotcrete output and even set-up ...

<p>Given the high deformability requirements of shotcrete in repair, rehabilitation, slope stabilization, ground support, and other applications, the use of fibers in shotcrete is growing. Growing also are challenges surrounding the use of fibers in shotcrete ...

Silica fume was first used in shotcrete in Norway in the nineteen seventies. In the early nineteen eighties the use of silica fume developed in North America, first in Western Canada and then in the United States. Silica fume has been added to both wet-mix ...
