- Synopsis
- The durability of cementitious material can be effectively improved by reducing permeability and by changing cement hydrates to a less soluble matrix. This paper describes the chemical and the mechanical properties of carbonated new cementisious materials containing belite-rich cement and γ-2 CaO·SiO2 as main components in order to evaluate the superiority to normal portland cement. Moreover, the renovation method using this high durability concrete is introduced.

- carbonation, γ-2 CaO·SiO2, durability, leaching, porosity, diffusion coefficient
