Ultra-fast hardening grouting material, ultra-fast hardening grouting mortar and hardened body
Provided are an ultrafast-hardening grouting mortar, an ultrafast-hardening grouting mortar, and a hardened body, which contain a specific amount of chlorine, and which are capable of improving durability by further improving neutralization resistance, adhesion strength with reinforcing steel bars, and anti-rust rate of the reinforcing steel bars. The ultra-fast hardening grouting material comprises cement, calcium aluminate, gypsum, a gas foaming substance and fine aggregate, and the chlorine content of the ultra-fast hardening grouting material is 3 ppm or more and 800 ppm or less.
提供含有特定的氯量、且通过更加提高抗中性化性、与钢筋的附着强度、钢筋的防锈率从而能够提高耐久性的超快硬灌浆砂浆、超快硬灌浆砂浆及硬化体。超快硬灌浆材料包含水泥、铝酸钙、石膏、气体发泡物质、细骨料，超快硬灌浆材料的氯的量为3ppm以上1,800ppm以下。
