Fresh state and hydration properties of high-volume lithium slag cement composites

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%; heat 300 J/g (at 72 h). At replacement levels above 40%, index, heat, fluidity significantly reduced. Experimental investigations confirm that test provides best correlation coefficients ( R 2 = 0.96) with maximum shear viscosity than content. classical slump rheological models used to characterise mini-slump, yield stress, plastic low high volume pastes. present study recommends a paste is viable option green concrete for optimum fresh, hydration, rheological, hardened properties.
