X射线、压汞、水化热研究表明,采用Ⅱ级粉煤灰与南浦-1型泵送剂相结合的双掺技术能延缓初期水泥水化速率而不影响水泥早期硬化,能改善水泥石孔结构。
X-ray, mercury intrusion, and hydration heat studies have shown that the use of a dual-blend technology combining Class II fly ash with Nanpu-1 pumping agent can retard the initial cement hydration rate without affecting the early hardening of the cement, and can improve the cement stone.
