    In the development of the present investigation, in the first instance tests were performed on the aggregates to form the masonry according to an initial dosage that allowed us to obtain good results at compression based on the INEN 3066 norm. The study addressed, opted for the substitution of the chasqui by 15%, 25% 50% and 75% sawdust, from which it was obtained that the handcrafted blocks have an approximate resistance of 10.96 kg / cm² and that under this parameter the blocks of 15 and 25% comply with the ranges established as original dosage unlike the artisan blocks, while the one with 50 and 75% sawdust is discarded, due to its very low compressive strength. On the other hand, within the present and following the Chilean regulations NCH 849 and NCH 851, a thermal and acoustic test was carried out, obtaining as a result that the block with 75% sawdust has greater thermal insulation capacity unlike the other blocks tested, while the block with 25% dosing of the aggregate has greater acoustic insulation capacity. Within the study addressed, the process carried out for both manufacturing and laboratory tests is clearly indicated, which generated feasible results, framed within the normative statutes for construction.
