Silica Powder 's research

Silica Powder began in the Scandinavian countries, the 1950s people on the role of Silica Powder on some understanding and preliminary research, but applied to engineering practice since the 1970s, first in Norway and Sweden and other countries in the port terminals, the North Sea oil fields and underground mines, part of the Silica Powder concrete, 1982, Norway V Nuowei Si dam formally adopted by the Silica Powder concrete in the early 1980s, Canada was established in Quebec Silica Powder concrete, and the large volume of Silica Powder concrete pilot study, mixing high-grade concrete 10,000 cubic meters in 1983, Silica Powder concrete to repair the card check on the Orinoco Funi River Dam stilling basin to good effect. The rest of the world are stepping up research and application. While China is not a long history of Silica Powder, just 10 years time, 1985 MEW East survey hospital research institutes and 10 of the MEW Engineering Bureau for the first time in the Sichuan Yuzixi two power plants in the trial of silica fume concrete, 3% to 7% plant Silica Powder in concrete in order to improve the early strength, and speed up the turnover of template, the desired effect, In addition, the diversion tunnel shotcrete, Silica Powder 715% in order to reduce the amount of rebound of the concrete, the park Dahuofang reservoir engineering, the the Longyangxia discharge structure and the Gezhouba Dam sluice gate repair project, the homes are using Silica Powder concrete, the better, IWHR durability of silica fume concrete and Silica Powder cement algae grouting material some research, and the basis of consolidation grouting of the Ertan Hydropower Station, the restoration of the Panjiakou dam overflow surface, well-being and Sichuan autumn power plant diversion spillway tunnel repair project the use of Silica Powder concrete, silica fume cement grouting . All of these, indicating that the Silica Powder concrete is increasingly important as a high-performance concrete in the project application date, so its performance, particularly its strength and durability of much attention.
