General description
TRXR-50MS adheres to cement hydration products to limit contact between cement and water. It also adheres to crystal nuclei to inhibit their growth, slowing cement slurry hydration.
Performance characteristics
- Contains cellulose derivatives, hydroxycarboxylic acids and several other compounds.
- Reduces cement slurry consistency and improves rheology.
- Usually dry blended.
- Effectively delays thickening.
- Non-toxic, odourless and non-corrosive.
