Mix proportion of eco-friendly fireproof high-strength concrete
Highlights ▶ The optimum mix proportion for eco-friendly fireproof high-strength concrete was derived. ▶ Derived mix proportion was reduced CO2 emitted/ton in 34.6% compared with using Type I cement only. ▶ The eco-friendly fireproof high-strength concrete is considered to be environment friendly.
Abstract The optimum mix proportion for eco-friendly fireproof high-strength concrete was derived in this study. The mixture of the concrete was evaluated by thermal performance through a fire-resistance test. To derive the optimum mix proportion, ground granulated blast-furnace slag and porcelain were substituted, and a 0.1vol.% fraction of polypropylene fibre was added to prevent spalling. Porcelain was used, as it is effective in improving residual strength. The RABT curve was adopted as the heating time–temperature curve for the fire-resistance test. The derived optimum mix proportion can contribute to ecological friendliness, as it produced up to 34.6% CO2 savings compared with the mixture using conventional cement. Furthermore, improvement in the characteristics of concrete was shown after exposing this mixture to high temperature following the addition of porcelain.
