早强泵送粉煤灰商品混凝土的研究与应用

Research on and Application of Pumpable Early-Strength Ready-Mixed Concrete with Fly Ash

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 Pressure and Hydration Heat Studies show that employing twin admixture Technique of grade IIfly ash and Nanpu-1 Pumping Agent can retard initial cement hydration rate without affecting early age cement hardening and can improve the pore structure of cement stone.
