  In pile foundation engineering, the non-autoclaved technique of PHC pipe piles has been a development tendency, and mineral admixtures are important raw materials in the production of high early strength and high durability PHC piles.In this work, the effects of glass microsphere and ground granular blast furnace slag (GBFS) on the strength development,durability, pore structure and microstructure of the non-autoclaved PHC pipe piles was studied.
