Polycarboxylate superplasticizers | |
the most wonderful water reducing admixture up to now | |
Advantages (compared with other superplasticizer) |
|
1. To maintain slump perfectly within 1-3 hours 2. Low dosage, and so to save cost in comparison with other superplasticizer at equal performance 3. High water reduction 4. To enable a much better flowability of the mixture 5. To improve the strength and durability of the concrete drastically 6. To save cement at equal strength and durability 7. Eco-friendly (no formaldehyde or benzene) 8. Resulting in low concrete shrinkage ratio to make sure better construction quality |
|
Disadvantages (compared with polycarboxylate superplasticizers) |
|
Naphthalene superplasticizer | 1. Big slump loss 2. Hard to avoid segregation when dosage is slightly higher 3. Certain pollution to the environment as formaldehyde or benzene content |
Melamine superplasticizer | 1. Air entraining performance is bad 2. Using cost is comparatively high 3. No highlight in its features |
Lignosulfonate superplasticizer | 1. Low water reduction 2. The performance is common 3. It’s from 1930s, and is coming to be eliminated products. Still used today only for being eco-friendly and people’s habit 4. Using cost is comparatively high |
