Non-dispersible underwater concrete admixture is a powdery agent composed of water-soluble polymers and surfactants. normally underwater civil engineerings are affected by water,and concrete particles may be separated or lost,thus rendering weakening of structure and environmental problem. if water is isolated,the engineering can be complicated and expensive. Non-dispersible Underwater Concrete Admixture is a good benefit in these conditions. it simplified the underwater engineering operation.

1.Features:

1. good anti-dipersibility. the product prevents concrete segregation,cracks and does not cause water pollution.
2. good fluidity.the product increases the viscosity of suspended concrete but decreases the viscosity of flowing concrete.
3. good water accommodation. in concentration =2%,concrete almost does not bleed.
4. retarded solidification.in concentration =2%,initial solidification was retarded for 1-3 hours and final solidification for 2-4 hours.
5. concentration can vary according to different engineering conditions.
6. the product is not poisonous and environmental friendly.

2.Usage

1. The product comes in the form of a powder added as a concrete admixture
2. 2-3% is a recommendation

3. Packing and storage

1. It is light brown powder in 25Kg PE/PP woven bag.
2. Kept away from moisture and rain.
3. Shelf life: 3 years.
