The invention relates to an intelligent management method and a system for a construction project concrete standard curing homoculture test block. The method comprises the following steps: S1, two attributes of a magnetic body being determined as two numbers representing binary; 2, arranging a plurality of magnetic bodies accord to a preset digital arrangement rule to form encrypted information; S3, embedding the encrypted information into the concrete test block corresponding to the encoded lattice to obtain the encrypted concrete test block; S4, when the encrypted concrete test block is sentfor inspection, identifying information obtained by identifying the magnetic body in the encrypted concrete test block, generating a binary encoded lattice according to the identifying information, and determining the binary encoded lattice as decryption information; 5, checking whether that decrypt information matches the encrypted information. Through the management method, the replacement of standard curing by the construction side and the submission of concrete test blocks under the same conditions are effectively prevented, and the concrete can not be tampered with after densification, thus ensuring the true quality of the construction project concrete.
