In the present study an evaluation of the effect of four additives on the ceramic body is made: fly ash, talc, kaolin and feldspar; with the objective of determining the best formulations that allow to develop, after the thermal cycle and without modifications to the current production process of a certain ceramic company, microstructures that increase the mechanical resistance of semigres ceramic tiles. The obtaining of the ceramic test pieces was carried out using the procedure and the formulation proposed by the production company. The properties studied were linear contraction percentage, water absorption and mechanical resistance to bending. The corresponding tests were carried out in accordance with the corresponding standards. The highest value of mechanical resistance to bending was 57.91 N / mm2 corresponding to ceramic specimens with the optimized formulation: standard body plus 2% talc and 2% kaolin.
