The present invention relates to a method for manufacturing an environment-friendly concrete block, which can express an environment-friendly texture; which can reinforce durability; and which can recycle industrial byproducts while minimizing cholorosis. According to an embodiment of the present invention, a method for manufacturing the environment-friendly concrete block comprises the steps of: preparing a base layer aggregate by mixing 20-30 wt% of slag powder and 25 wt% of water to 100 wt% of cement; inserting the base layer aggregate in a mold frame and forming a first molded material by a first pressing process; preparing a surface layer aggregate by mixing 5-10 wt% of slag powder and 25 wt% of water to 100 wt% of cement; preparing a spray aggregate by mixing not greater than 12 wt% of cement (except 0 wt%) and 15 wt% of water to 100 wt% of aggregate; laminating the surface layer aggregate on top of the first molded material and forming a second molded material by spraying, coating and vibrate-pressure-molding the spray aggregate on top of the surface layer aggregate; curing the second molded material; and processing the surface of the second molded material which is completed with the curing.
