High performance specialty thickener VISCO TOP
For superior workability and high quality construction
Background & challenges
Risk of damage due to aging and natural disasters
Aging of infrastructure and shortage of workers in the construction industry are accelerating. While the burden of maintenance and upgrades is increasing, there are concerns that waterside facilities, such as ports, quays, and river management facilities, in particular, will be damaged due to aging, and that collapse resulting from natural disasters will cause serious damage to the surrounding area.
Concerns about water pollution surrounding construction in the vicinity of underwater and rivers
There are growing concerns that concrete poured in water and at the waterside may contaminate waterways around the construction site and impact on the natural ecosystem.
High performance specialty thickener, VISCO TOP
VISCO TOP is a concrete thickener comprised primarily of a surfactant, and imparts a variety of physical properties to concrete, including thickening and the prevention of material segregation in water to realize superior workability and reliable construction quality.
Features
①Superior workability
- Maintains high fluidity even with increased viscosity
- Superior flow properties allowing it to be poured into narrow spaces
- Can be easily cleaned with high pressure water
②Reliable construction quality
- Prevents material separation in water
- Demonstrates superior material separation resistance and seepage prevention
SOLUTION
Prevents material separation in water
Slurry will not separate, even in water
VideoRheology modifier VISCO TOP
High fluidity
Flows freely even when thickened
High flowability of VISCO TOP concrete
Flows freely without contaminating the surrounding water
Anti-washout concrete with self-flowing properties
Prevention of material separation & seepage
