SELF-HEALING CONCRETE POLE FOR CENTRIFUGAL MOLD USING SELF-HEALING INORGANIC BINDER PASTE AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a self-healing concrete pole for centrifugal molding using a crack self-healing inorganic binder paste and a method of manufacturing the same. The present invention uses a crack self-healing inorganic binder paste that is a combination of conventional cement mixture, blast furnace slag fine powder as an industrial by-product, desulfurized gypsum as a by-product of thermal power plant and Na ₂ SO ₄ , but considering the chemical balance of crack width By deriving the formulation and centrifuging at a significantly low water-binder ratio, not only Calcite but also needle-like crystals (AFt, such as ettringite) are produced, which has self-healing performance for 0.25 mm crack widths in which cracks are filled. Self-healing concrete poles for centrifugal molding can be provided.
