Ready-mixed concrete inducer RUBURI

RUBURI

Inducer for pumping ready-mixed concrete replacing with a mortar inducer.

Registered in each prefecture's new technology and new construction method utilization system

  • Registered in NETIS(system for utilizing new technology in public works, etc.) in Ministry of Land, Infrastructure, Transport and Tourism (MLIT) as CB-180006-A
  • Under JIS deliberation (Adopted in standardization system for new market creation in Ministry of Economy, Trade and Industry (METI))
  • Registered in new technology and new method in Shizuoka

Features and specifications
  • 90% reduction of the waste of mortar inducer
  • Unnecessity of 1 vehicle for mortar inducer (leading to CO2 reduction)
  • Eco product reusing sludge of ready-mixed concrete
  • By adding cellulose nanofiber (CNF) in order to further improve the conventional product, RUBURI has been reborn as the inducer with much higher strength.

Components of RUBURI


(1) Porous calcium carbonate
* It is calcium carbonate formed by particle size adjustment and component adjustment of sludge generated from the ready-mixed concrete plant with patented technology.
(2) Porous calcium carbonate containing hydrotalcite
*It is a fine powder composed of only hydrotalcite and calcite, which has a high degree of fineness in calcium carbonate formed by particle size adjustment and component adjustment of sludge generated from the ready-mixed concrete plant with patented technology.
(3) Precipitable calcium carbonate [synthetic calcium carbonate]
* It is micronized calcium carbonate with uniform particle shape by chemical treatment.
(4) Organic fluorescent pigment
*Using highly visible pigment manufactured by DayGlo Color Corp.
(5) Cellulose nanofiber (CNF)
*It is a cellulose fiber sleaved to the nano level.
(6) Cellulose fiber
*It is a micro size fiber generated from virgin pulp.
(7) Erythorbic acid

Precautions for use
  • Be sure to wear working gloves when constructing, removing, or moving, etc. RUBURI by hands.
    Store RUBURI in the attached pail can or airtight container.
  • The pH of RUBURI solution is alkaline. Wear rubber gloves to prevent rough hand skin.
  • RUBURI may be blown off by a gust of typhoon, etc.. If stormy weather is expected, fix or remove it.
  • Dispose RUBURI basically as it has no solidification ability.
    *However, even if RUDURI mixes into something, the strength will not be reduced if the volume ratio is about 1%.
  • If water is separated in the RUBURI solution after preparation, RUBURI can be used by mixing again.
  • Dispose RUBURI in the same way as the residual concrete.
