Counterweight concrete: after years of research and technical breakthrough in concrete, the density of new concrete produced by our company with self-made counterweight materials and high-quality chemical additives can reach 2.5-5.5tm3. Using counterweight concrete, a high-density special concrete, as ballast and counterweight, its biggest advantage is that it can replace cast iron counterweight, reduce cost, and meet the counterweight of various shapes and structures. At present, it has been widely used in the field of bridge and construction machinery counterweight and railway high-density concrete weight.

Counterweight concrete: after years of research and technical breakthrough in concrete, the density of new concrete produced by our company with self-made counterweight materials and high-quality chemical additives can reach 2.5-5.5tm3. Using counterweight concrete, a high-density special concrete, as ballast and counterweight, its biggest advantage is that it can replace cast iron counterweight, reduce cost, and meet the counterweight of various shapes and structures. At present, it has been widely used in the field of bridge and construction machinery counterweight and railway high-density concrete weight.
Scope of application
Counterweight concrete is mainly used for bridge box girder counterweight (large and medium-sized highway and railway bridges, which fully meet the use of cast-in-situ beams, precast beams and steel box girders), building anti floating counterweight (anti floating counterweight of underground garage, sunken square, underground station, underground structure foundation of main podium commercial complex), mechanical counterweight and large counterweight components.

Construction process
Construction of Jiu tong® counterweight concrete:
Jiu tong® counterweight concrete shall be centrally mixed in the mixing plant and measured automatically. The concrete shall be transported to the site by tank truck, poured by truck pump and vibrated by immersion vibrator.
Preparation before construction→ Raw material measurement → Jiu tong® counterweight concrete mixing → Discharge → Transport to site →Concrete pouring
Packaging and storage
Packed in PP bags, with a net weight of 25kg / bag and a shelf life of 3 months; It must be stored in a dry and ventilated room, and the packaging bag shall be sealed. Avoid moisture and freeze.
