Evolution of the Mass Balance of Water in the Hardening Process of Cement Compositions

摘要

Hardening and strengthening of cementitious materials is the result of simultaneous growth and interaction(in the thermodynamic sense)of chemical and structural transformations [1].The source material,a visco-plastic mixture,gradually transforms into artificial stone with dominating elastic properties.A characteristic feature of the hardening of cement systems is the interaction between their liquid and solid phases.The liquid phase-the pore-filling solution,is a structural component,which binds together solid-phase elements of different dimensions and configurations.The structured liquid phase is a dispersed matrix-1ike medium that has a direct contribution to the strength balance of the material.
