Meyco SA 160
MEYCO SA 160 high performance alkali-free set accelerating admixture isÂ
for use in the wet-mix spraying process. It is a liquid additive whose
dosage can be varied to the desired setting and hardening times.
Features
Overhead layer thickness of 6-12 in. (150-300 mm) in a single
application (as with aluminate based accelerators)
Good early strength development
Limited decrease of final strength
Benefits
Easy handling, as well as easy and efficient addition to the sprayed
concrete
Little dust and therefore a better working environment
Reduces required handling precautions, improving economics
þ
Meyco SA 430
MEYCO SA 430 high-performance accelerating admixture is used mainly in
the wet spraying process, but can also be used in the dry spraying
process. MEYCO SA 430 liquid admixture is an accelerator whose dosage
can be varied to the desired setting and hardening times.
Features
Faster setting and higher early strengths
Low consumption
Easy to mix into the concrete, even at low temperatures
Low viscosity
Benefits
Produces quality shotcrete
Improves adhesion and surface bond
Higher ultimate strengths and more durable shotcrete compared with
traditional accelerators
Increased layer thickness possible |
