It is ground-breaking in the sense that overrule common sense.! "changed"all obayashi"eyeball technique insane sense seawater mixing concrete" (page 1 of 8)-technology changed the insane construction common sense challenged the taboo [try again] SankeiBiz . Concrete using uncleaned sea sand and sea water has been ruled out from fracture expansion that, in civil industry, causing corrosion of reinforcing steel.
Vice President major general contractors, obayashi, Makoto kanai (66) overcome this barrier and development of sea water mixing and sea sand concrete high strength. Use expanded East Japan earthquake dash blocks for revetment, including aircraft from used water while exposed also frowned upon premises taken spearhead the commercialization of technology.
Was now aimed at infiltration by "all obayashi" eyeball technique. Benefits of rock salt layer focuses on "Finally, the first step in ".
2/12, Kanai bucked the dearly in sight for long-sought technology stood boardroom obayashi gumi 27F headquarters in Shinagawa, Tokyo. Costly ground-breaking is not available near the ocean or freshwater satisfied in offshore construction site in ground-breaking first place sand taken from the sea, can be used and there is strength, and cum is doing exactly what ground-breaking!
It is great. What an honest research bore fruit. This is a strained it is mirror technicians diligently researched and decided.
It is great.
This book is found out that concrete alkali-aggregate reaction. To doubt common sense needs is the opportunity. Development of obayashi Corporation above and find the actual obayashi Corporation made a radioactive waste disposal site from 1983-85, spread across the U.S., New Mexico desert 650 meters underground rock salt layer.
Strength concrete-like strong layer of rock salt.
Shown how much water or leaking hydraulic conductivity has confirmed benefits could be contained low levels of radiation, high airtightness and concrete 1/100. However, natural rock salt layer does not exist in Japan. Kanai strikes we'll "take artificial salt make it". "If you make a stiff structure concrete. It's salt from seawater, nice concrete in seawater ".
Earnestly the voices internally to form a project team. There are these kind of things. But through chance although "seawater with concrete good" idea of, I usually like the impossible.
Genius is what such insight is necessary.
I hope so that reconstruction work advances fast with this. ↓ cement plants also are missing.
People think is pochi I and m (_ _) m
