Abstract

The authors developed an eco-friendly concrete that fixes a large amount of carbon dioxide in the hardened cement paste through use of the carbonation reaction of concrete. Preparation of highly durable glass fiber-reinforced mortar is possible by virtue of the neutral pH characteristic of said concrete as the result of carbonation. The applicability of this glass fiber-reinforced mortar for residual forms was investigated from the viewpoints of strength and durability. The results show that compared with regular glass fiber-reinforced mortar, the newly developed mortar offers superior strength and durability, and thus it is deemed suitable for use for residual forms.
