3. Ta yaya suke shafar ƙarfin kankare?

Both increase strength by allowing a lower water-cement ratio. Duk da haka, PCEs typically achieve higher ultimate strengths for a given slump. Their superior dispersion creates a denser, more homogeneous paste with fewer flaws. Naphthalene-based products can sometimes cause minor air entrainment, which slightly reduces strength. For projects demanding 10,000+ psi kankare or maximum durability, PCE is the preferred choice.

4. Are there cost differences?

Ee. Naphthalene-based superplasticizers are generally cheaper per liter. But cost-effectiveness isn’t about unit price. PCEs are much more efficient. You use a significantly lower dosage—often 1/3 ku 1/2 of a typical naphthalene dose—to achieve the same water reduction.
