Abstract In this study, the fresh state and hydration properties of 0–60% lithium slag blended cement pastes were investigated at water-binder ratio 0.47. The workability was evaluated by measuring air content, marsh cone flow, mini-slump setting times, through rheology tests. A 40% could produce 91% strength activity index 28 days; pat diameter 70.54 mm; flow efflux time 145 s; content 0.6%; h...
