Quotation for non dispersing flocculants underwater

Description :

　　Underwater non dispersing concrete flocculant

　　Model: HY-UWB

　　Execution standard: DL/T 5100-200 "Technical Specification for Hydraulic Concrete Admixtures"

　　Underwater non dispersing concrete flocculant is suitable for various underwater concrete projects. The flocculant is a powdery concrete admixture composed of water-soluble polymer, surface active substances, etc. It has strong anti dispersion and good flowability, achieving self leveling and self compaction of underwater concrete, suppressing the dispersion of cement and aggregates during underwater construction, and the construction water area. The compressive strength of underwater concrete with non dispersing concrete flocculant added can reach more than 70% of the strength of onshore concrete with the same ratio when the water drop is 0.3-0.5m.

　　Underwater non dispersing concrete flocculants can be used for sealing the bottom of sunken wells, cofferdams, caissons, stone throwing grouting, pouring underwater continuous walls, leveling and filling underwater foundations, RC slabs and other underwater large-scale projects without construction joints, large-diameter cast-in-place piles, docks, dams, reservoir repairs, waterproof impact reinforcement of drainage outlets, underwater abutments, seawall revetments, slope protection, sealing and plugging of piles, as well as underwater projects that are difficult to construct with ordinary concrete. Underwater non dispersing concrete flocculants are not limited by water depth, construction surface, or concrete volume (various underwater projects have been constructed at a depth of 37.8m, with concrete volumes ranging from a few cubic meters to several thousand cubic meters). During the construction of concrete in tidal sections, it is also not affected by tides.

　　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.

　　Underwater non dispersing concrete flocculants can be formulated with C15-C40 underwater non dispersing concrete according to the needs of underwater engineering to meet different construction performance requirements. The slump of non dispersing concrete underwater can reach 18-24cm, without bleeding or segregation. Initial setting time is 5-40 hours, final setting time is 10-50 hours, and the setting time can be adjusted. The impermeability can reach S20 or above, and the corrosion resistance coefficient is not less than 0.85. The underwater non dispersing concrete flocculant has good compatibility with other additives, and the addition of air entraining agent can prepare D300 anti freezing and thawing concrete. There is no rust on the steel bars.
