Based on the data from the concrete test, a production company performs tests on a new accelerator admixture for concrete with which it is intended to stabilize the resistance of 250 kg / cm2 concretes developed with the three types of cement: pozzolanic I, pozzolanic II, pozzolanic III. Perform a 95% LSD discriminant test to determine whether or not there is a difference in the strength of the concrete.
