摘要：
The relatively poor reactivity of Indian BF slags results in lower strength of slag cement in comparison to OPC. In this investigation, a dosage of waterglass as an activator has been optimised. Percentage substitution of slag, concentration of waterglass, and their effects on properties of activated PSC have been studied. Up to 60% slag substitution and use of 1% waterglass as activator have yielded the best results. The activator has also acted as a grinding aid. Long-term storage of activated slag cement has been found to be detrimental. (C) 1998 Elsevier Science Ltd.
