a) The mixing order of the components is water - cement - solid additives - liquid additives;
b) Cement and solid additives (when used) are dosed by weight;
c) The mixture is made by mechanical means and never manually;
d) The agitation time depends on the type of equipment, but never less than 3 minutes in high turbulence mixers; other values depend on the specifications of the equipment, being obtained previously;
e) The equipment used is sufficiently potent to permit the preparation of a homogeneous grout at such a speed that complete dispersion of the cement particles is achieved without agglomerations and false resistance.
