本研究は、低炭素複合セメントCEM II/B-M(V-LL)-42.5Rを用いたモルタルにおける3世代の可塑化混和剤(リグノスルホン酸塩、ナフタレンスルホン酸塩、ポリカルボン酸エーテル)の比較評価を行った。ポリカルボン酸エーテルは最大30%の減水効果と240mmの流動性を示し、セメントのCO2強度を約14%削減した。これらの結果は、低炭素建設材料の実用化に貢献する。
English
This study compares three generations of plasticizers (lignosulfonates, naphthalene sulfonate, and polycarboxylate ethers) in low-emission composite cement mortars. Polycarboxylate ethers achieved water reduction of 25-30% and flow ability up to 240 mm, reducing CO2 intensity by ~14%. The findings support the development of low-carbon construction materials.

📄 Abstract(原文)
The article presents a comparative investigation of three generations of plasticizing admixtures – lignosulfonates (LS), naphthalen sulfonate (SNF), and polycarboxylate ethers (PCE) – in cement-sand mortars based on low-emission composite Portland cement CEM II/B-M(V-LL)-42.5R. The technological and technical effects of admixtures were evaluated. Testing was performed on standard sand according to DSTU EN 196-1 and quartz sand from the Mykolaiv quarry. The results showed that PCE provide water reduction of 25–30% and cone flow ability to 240 mm, while LS provides a moderate effect (flow ability 160–165 mm), and SNF provides an intermediate position with a pronounced dependence on Na₂SO₄ content. Among lignosulfonates, calcium LS demonstrated higher strength compared to potassium LS. The application of PCE in combination with composite cement provides a reduction in CO₂-intensity by ~14% compared to the control mix.
