The invention provides a special-shaped refractory brick refractoriness under load and compressive creep test method. The special-shaped refractory brick refractoriness under load and compressive creep test method comprises the following steps that firstly, according to brick shapes and sizes of special-shaped refractory bricks, samples with sizes approaching to given sizes and similar shapes in a national standard or a smelting standard are prepared; secondly, the actual stress area of the samples is calculated through a seal method; thirdly, loads are exerted on the samples, and the loads are regulated according to the proportion relation between the standard stress area of the samples and the actual stress area of the samples to enable pressure stress acting on the samples to reach standard required demands; fourthly, refractoriness under load or compressive creep tests are carried out according to normal program steps, and test results are recorded. The sample sizes and test parameters can be regulated according to the shapes and the sizes of the special-shaped bricks, the two important high-temperature performance indexes of creep rate and refractoriness under load of lattice bricks can be accurately detected, and the test results can truly and accurately reflect the actual using performance of the lattice bricks.
