C50 High-Strength Pumpable Concrete

Product Characteristics:

Utilizes high-range water reducers and quality SCMs to achieve high fluidity and self-compacting properties at low water-to-binder ratios,facilitating pumping to great heights.Develops early strength rapidly,shortening construction cycles.The high strength allows for smaller structural member cross-sections,increasing usable space.Its high density results in superior impermeability,freeze-thaw resistance,and durability compared to standard concrete.

Product Specifications:

Strength grades typically range from C50 to C80.High workability is essential,with slump usually≥180mm and flow spread≥500mm.The water-to-binder ratio is strictly controlled,often below 0.34,to ensure high strength and durability.Requires high-quality raw materials:high-grade cement,hard/clean aggregates,and significant SCM content to improve microstructure and long-term performance.

Product Application:

Primarily used for vertical load-bearing structures like frame columns and core shear walls in high-rise and super-tall buildings.Used for key components like box girders and piers in long-span bridges.Also suitable for column foundations in heavy-duty industrial plants,precast piles,nuclear power facilities,and other applications with special strength and durability requirements.Requires specialized high-pressure pump trucks for placement.
