With the progress of human society, the exploitable land resources are relatively less and less, while the ocean, which accounts for 70% of the earth's area, is rich in mineral resources, so the development and utilization of marine resources is imperative.

As we all know, although cement is a hydraulic material, if it is directly dumped into water, in the process of falling, due to the washing effect of water, aggregate and cement are separated, some of them are taken away by water, and some of them are suspended for a long time, which can not meet the engineering requirements.

Wanzhao Chemical uses a unique process to develop and prepare high-quality concrete anti-dispersant. The 7-day and 28-day water-land strength ratios of underwater non-dispersible concrete made from it meet the requirements of the specification, and the dosage usually only needs 1-2kg/ ton of concrete, which has the advantages of low dosage and high performance.
