UWB underwater non dispersing flocculant for underwater concrete construction

Description :

　　Performance of UWB underwater non dispersing concrete

　　(1) Anti dispersibility

　　UWB underwater non dispersing concrete flocculant has strong anti dispersibility even under the scouring effect of water, which can effectively suppress the increase in pH and turbidity generated during underwater concrete construction.

　　Mix proportion of ordinary concrete before and after falling into water (value is volume percentage)

　　UWB underwater non dispersive concrete mix ratio before and after falling into water (value is volume percentage)

　　(2) Excellent construction performance

　　Concrete and mortar mixed with UWB flocculant are rich in viscosity and plasticity, with excellent self leveling and filling properties. They can be filled by their own weight between densely packed steel bars, skeleton and formwork gaps.

　　(3) After adding UWB flocculant, the water retention of concrete can be improved, and there will be basically no bleeding or floating slurry.

　　(4) The concrete mixed with UWB flocculant has a slightly longer setting time compared to ordinary concrete.

　　(5) UWB underwater non dispersive concrete is easy to pump, and by adjusting the flowability of underwater non dispersive concrete, the pumping distance can be ensured to be around 200 meters.

　　(6) Strong adaptability

　　Freshly mixed UWB underwater non dispersible concrete can be poured using different construction methods and can be compounded with various additives to meet different construction performance requirements.

　　Compared with conventional underwater concrete, underwater non dispersive concrete greatly simplifies the construction process, making underwater concrete construction more land-based and reducing the risk of construction to a certain extent. Moreover, this technology can also realize special structures such as thin-walled, narrow, and irregular underwater structures that were previously impossible to construct. Underwater non dispersing concrete flocculants have excellent water resistance to dispersion, and do not disperse or segregate when falling into water, with little loss of cement. Concrete has good fluidity, and when poured in water, it can self level and self compact without the need for underwater vibration, simplifying the underwater construction process.
