PURPOSE:A solidifying agent of cement that contains cement and an inoganic ammonium salt, thus being capable of rapidly solidifying even organic soil containing humus in a short time. CONSTITUTION:An inorganic ammonium salt as ammonium sulfate is added to a solidifying agent of cement. The addition of the inorganic ammonium salt to cement accelerates the hydration of cement even when the soil contains humus that inhibits the hydration reaction. Futher, the formation of ettringite is observed, which is thought to be a factor to develop the high strength. |
