| Abstract: | Through comparative test with reference concrete, the auto-shrinkage of concrete with composite aggregate can reduced significantly. For concrete containing silica fume or ground slag, the reduction of auto-shrinkage is more effective by composite aggregate. The measuring instrument of concrete auto-shrinkage is designed by oneself. |

| Keywords: | auto-shrinkage composite aggregate high strength concrete ground slag silica fume |
