Abstract: PURPOSE: A method for manufacturing a cracking control type basic floor for packing using reinforcing fiber and fly ash is provided to efficiently control reflection cracking of a basic floor using reinforcing fiber without using an admixture such as an expensive expansive admixture or a shrinkage reducing agent. CONSTITUTION: A method for manufacturing a cracking control type basic floor for packing using reinforcing fiber and fly ash is as follows. Cement is replaced with fly ash so that an initial strength degradation of a basic floor is induced. Reinforcing fiber is mixed with the manufactured basic floor for controlling an initial reflection cracking. 60 to 70 weight% of the fly ash is replaced with respect to 100 weight% of the cement. 0.2vol% of the reinforcing fiber is mixed with respect to 100vol% of the basic floor.
