wave block

Full-solid waste wave-proof blocks can be produced by using harbor dredged sea mud, engineering muck, and geopolymer cementitious materials made of steel slag powder and fly ash through grinding and chemical activation. Steel slag gives strength and erosion resistance, and geopolymer cementitious materials replace cement to improve corrosion resistance.

Functional reef

When making fish reefs, the aggregate is made of harbor dredged sea mud, engineering muck, and tail slag, combined with geopolymer gelling materials, and a suitable amount of organic additives that can effectively promote the adhesion of seaweed on the concrete surface are added. Metal elements such as iron and manganese contained in steel slag and tail slag also help seaweed adhere.

sand-fixing materials

Sand blowing to build an island requires sediment to quickly bleed water and settle, harden and form bearing capacity. We provide agents that can be quickly and uniformly mixed during the sand pumping process and can be separated after blowing and filling. At the same time, it is combined with a gelling material that can adjust the setting time to realize the mixing of the agent and the gelling material during the pumping process. After blowing and filling, rapid bleeding and settlement are achieved and bearing capacity is formed early.
