Zusammenfassung: | The present invention relates to a concrete early strength agent, blending water, a concrete composition, and a method of preparing the concrete composition. The present invention relates to a technique of rapidly ensuring, at a low temperature, a compression strength expression rate of concrete by the early strength agent included in a mixture of concrete. More specifically, the concrete composition is synthesized with the concrete early strength agent comprising 25-55 wt% of an alkaline compound; 15-30 wt% of sulfur trioxide; 1-5 wt% of carbon; 6-34 wt% of potassium hydroxide; 10-40 wt% of silicon dioxide; 10-40 wt% of nitrogen; and 1-4 wt% of oxygen; 160-180 kg/m^3 of the blending water in which the early strength agent is contained; 340-400 kg/m^3 of general Portland cement (200); 830-910 kg/m^3 of fine aggregate (310); and 900-990 kg/m^3 of coarse aggregate (320). The concrete composition has a fast strength expression rate at a low temperature.
