The present invention is a fast setting strength development current 3 to 55% by weight, fine aggregates 5 to 70% by weight, coarse aggregates 3 to 60% by weight, function improving agent 0.01 to 30% by weight and water for emergency repair containing 0.1 to 30% by weight It relates to a light cement concrete composition and a road pavement repair and reinforcement method using the same. The ultra-fast cement concrete composition for emergency repair according to the present invention can improve the workability of concrete, improve the strength of concrete, and in particular, improve abrasion resistance, impact resistance, corrosion resistance, prevent cracking, and greatly improve durability. I can. In addition, it is possible to make dense concrete by promoting initial hydration of cement and densification of the structure, thereby improving the strength and durability of concrete. In addition, it is possible to provide an effect capable of exerting an effect of preventing surface cracking and expansion failure due to drying shrinkage. |
