Institute of Civil Engineering, Qingdao Agricultural University, Qingdao 266109, Shandong, China) Abstract: The hydration characteristics of slag in cement–slag binder at different slag ratios were investigated via measurements of reaction degree of slag, Ca(OH)2 content in hardened paste and mole ratio of Ca to Si of formed silicate calcium hydrate (C–S–H) gel. The results show that a greater slag ratio in cement–slag binder leads to a lower reaction degree of slag, and the effect of slag ratio on the slag reaction degree is not obvious within certain limits ( 70%). High temperature could improve the slag reaction degree i
