The aim of this research was to provide values for different material properties considered in either traditional or more recent numerical silo design methods. Different samples of granular agricultural materials commonly stored in silos were tested. Common geotechnical devices have been used in order to make the replications easier. Based on these experiments it was determined that the different material properties were not affected by the test velocity, except in the case of Poisson ratio. From a practical point of view, the test velocity correlates well with the sliding velocity of grain during discharge. The values obtained for material properties considered in traditional silo design methods were similar to those reported by other authors. No significant differences were observed in the results obtained when using either the square shear box or the circular shear cell. The same conclusion was reached when comparing the results from direct shear tests with preconsolidated and unconsolidated samples. This means that simplified devices and procedures can be used in agricultural grains against other products. Finally, a table with the recommended values for the different parameters determined for each sample tested was provided in this work.
