PROBLEM TO BE SOLVED: To provide a construction method for a floor slab concrete capable of enhancing the durability of the floor slab concrete including the load bearing capability by accurately estimating whether surface cracking occurs or not to sufficiently prevent cracking from occurring even when the surface of the concrete after curing is exposed to rainwater or sunshine. SOLUTION: Weather data on the amount of solar radiation and the atmospheric temperature in the period from the placement of the concrete to the complete hardening thereof is estimated from the data in the past. Based on the weather data, the cracking of the concrete occurring between the period from the curing to the complete hardening is estimated. When the occurrence of cracking is estimated, the quantity and the diameter of reinforcements 4 are selected according to the degree of occurrence of the cracking, the reinforcements are disposed in a mold frame beforehand, and the concrete is placed in the mold frame.
