Rokkon Price In Bangladesh

Description

DESCRIPTION
Sika® Rokkon C is available in cartridge form enclosed
in a water permeable membrane and protected by a
polyethylene cover.
At the time of application, take the cartridge out of the
polyethylene cover and put it in water, allowing
enough water through the membrane to form a nonshrink, thixotropic cementitious grout.
Additives in the grout ensure controlled expansion to
stabilize the grout and control the water uptake to
provide an optimum w/c ratio for high early strengths.
The overall cohesiveness of the grout enables it to be
used in wet conditions, even in flowing water without
excessive grout washout.
USES
Sika® Rokkon C is used for grouting rockbolts for strata
reinforcement in tunneling and mining to reduce roof
collapses.
CHARACTERISTICS / ADVANTAGES
Sika® Rokkon C will provide the following benefits:
Reliability: Laboratory tested pre-packed materials
avoid risks of unpropered grout mixing & placing.
▪
Non shrink: controlled expansion counteracts shrinkage to provide effective contact with rock
▪
Chloride free: develops early strength without the
use of chloride and makes it safe to use with embedded steel.
▪
Encapsulated: minimizes grout loss from overhead
holes or under conditions of running water.
