摘要: This paper focuses on the determination of consolidation characteristics mineral materials. The main objectives were to improve measurement accuracy and reduce test duration. Consolidation govern fluid migration evolution properties; compressibility, permeability coefficient are required describe hydro-mechanical behaviour. In this paper, a method is proposed. After compressibility permeability, as function void ratio was computed. applied two different materials: clay material (kaolin paste) fresh cement paste. results obtained compared with commonly used methods described in national standards; comparison showed that developed procedure quicker provides more reliable results.
