Abstract The factors affecting the accuracy of specific surface area were discussed. Based on the production practice, the influence of density, voidage and air viscosity factors on the instrument were analyzed in detail, and then the correction methods were proposed. When the error between the density value and the true value of cement was within ±0.04g/cm3, the specific surface area value and accuracy value are in the permissible error range. When the input of voidage [ε] was not 0.5, it should be changed according to the formula of ε3/2/(1-ε)2/2.
