Material for improving plasticity of sludge flow

Hello, I would like to ask what materials can improve the fluidity of silt? There are several materials that can improve the plasticity of sludge flow:

1. bentonite: an aluminosilicate with layered structure, which can be modified by ion exchange technology to improve its adsorption and plasticity.

2. Clay: It has a layered crystal structure, and its fluidity can be improved by adding dispersant, kneading and heat treatment.

3. Foam: It can be used as a reinforcing material to improve the impermeability and plasticity of mortar.

4. Polymers: Some high molecular polymers can be used as additives to improve the rheology of mortar.

5. Water-soluble polymer materials, such as CMC, can be used as thickeners to improve the fluidity of sludge.
