The super early strength filling materials with high performance was developed by 42?5 ordinary portland cement, high alumina cement, multicomponent complex system of gypsum with many kinds of additives. The different cement-sand ratios, expansive dosage, and the micro structure of cement-sand ratio 1?5 were studied. The results showed that the system supplemented by a variety of additives was that the initial fluidity was 325mm, 30min fluidity was greater than 280mm, final setting time was (50 ± 5) min, 1d flexural strength was 13?58MPa, 7d flexural strength was 17?92MPa, 28d compressive strength was 99?6MPa. The micro structure of the system was compact and dense, expansion properties met the requirements.
