| Abstract: | The influences of the fly ash and ground slag on performances of the strength, contraction, frost-resistance, impervious of Cl- and elasticity modulus of the LC45 light-weight concrete was researched. The rational application method and proportional ratio of combined mixtures with fly ash and ground slag for light-weight concrete.was put forward. |
