High Durability Concrete using Mineral Admixtures cured with CO₂ Gas

Abstract

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.
