a XRD patterns of AACW before and after wet grinding. b Compressive strength development at varying WSA replacement levels (Note: The lower compressive strengths (<120 MPa at 28 days) are due to the exclusion of steel fibres in this study). c Hydration heat evolution as a function of ultrafine WSA dosage; and d Cumulative heat release over time.
