摘要

•Dilatancy of cement powder paste is caused by long polymer chains of superplasticiser.•Adequate superplasticiser decreases dilatancy because of better particle packing.•Partial replacement of cement by pozzolanic filler can decrease dilatancy.•Dilatancy of cement powder paste decreases as wet packing density increases.
