Non-explosive static demolition agent including CaO clinker powder and amorphous compound containing CaO, MgO, Al2O3 and SiO2 is provided to control hydration rate, to improve workability, to embody excellent expression of expansion pressure and to ensure time for the expression by combining the CaO powder with the amorphous compound to show pozzolan reactivity and potential hydraulicity of the combination. The demolition agent comprises: 70-95wt.% of CaO clinker powder obtained by baking lime at 1300-1400deg.C; and 5-30wt.% of amorphous compound that contains CaO, MgO, Al2O3 and SiO2 and has alkalinity of 1.6-2.0. The amorphous compound consists of 40-50wt.% of CaO, 1-20wt.% of MgO, 10-25wt.% of Al2O3 and 33-38wt.% of SiO2. The demolition agent has expansion pressure of 200-300kg/cm^2 within 8 hours. |
