The aim of this study is to establish the general equation for the prediction of 28 day strength from the result of earlier test. Almost all of the research work published is practiced to find suitable and practicable method of earlier testing to obtain reliable relation between earlier strength and 28 day strength. But the compliance criterion for the result of earlier test has not been established in these works. In this study, the general equation for the prediction of 28 day strength from the result of earlier test is derived in consideration of stochastic propertiec of concrete strength and that of the result of earlier test. General equation derived is as follows : [numerical formula] where [numerical formula] F_<28> : Estimated value as 28 day strength F_a : Result of earlier test a, b : Coefficients of regression equation in correlation between earlier strength and 28 day strength S_e : Standard error in correlation between earlier strength and 28 day strength σ_<28> : Standard deviation in 28 day strength A : Coefficient shown in Table 3
