摘要
The present invention relates to a high early strength type mixed cement concrete composition for bridge pavement by using a high early strength type mixed cement binder and a bridge pavement method using the same and more specifically, to a high early strength type mixed cement concrete composition for bridge pavement by using a high early strength type mixed cement binder and a bridge pavement method using the same in which a hydration reaction accelerator and a mineral admixture such as blast furnace slag and fly ash in order to improve resistance against chloride ions and early age strength which is a defect of mixed cement. The high early strength type mixed cement concrete composition of the present invention for bridge pavement by using a high early strength type mixed cement binder has a technical significance by comprising 14-20 weight% of a high early strength type mixed cement binder; 35-50 weight% of fine aggregate; 30-35 weight% of coarse aggregate; 5-10 weight% of water; and 1-10 weigh% of synthetic polymer.
