Influence of Caustic Soda Flakes-Phosphogypsum on Activation and Microstructure of Carbide Slag-Flyash

摘要：

　　This article studied the influence of the caustic soda flakes (CSF)-phosphogypsum (Ard) activator on the properties and microstructure of hydration product generated by carbide slag(CS)-flyash(FA) system which used in high-grade highways pavement.Studies have shown that:the main hydration products generated by carbide slag-flyash system are calcium silicoaluminate hydrate (C-A-S-H) and ettringite (AFt),but the reaction of hydration is slow and the content of hydration products is low.However,the caustic soda flakes-phosphogypsum can promote the formation of C-A-S-H and AFt,so can improve the strength and engineering application of the system effectively.
