The sampling of small size concrete cores which diameters are from 18 to 25mm from RC structure gives only a little damage to the structure. Therefore small size cores can be sampled from main structural members such as columns and beams. In the present paper, the population mean and variance of strength gap between small size cores and standard size cores which are 100mm in diameter and 200mm in height are discussed, and the formulas for estimating the strength of concrete in RC structures are determined. Furthermore, the estimating method is applied to actual structures and the adequacy is considered.
