Abstract

Given the need to optimize construction processes, this study evaluated and compared the costs and productivity of partial and total mortar methods in structural block masonry. The analysis includes electronic spreadsheets to survey unit and total costs, as well as on-site monitoring of worker productivity. The partial mortar system proved to be more advantageous for blocks with intermediate resistance (6 MPa and 12 MPa), reducing costs by up to 4% due to the lower mortar consumption . It also demonstrated greater uniformity in productivity, with an average of 17.62 m²/day per worker, helping to increase the efficiency of the work without compromising structural quality. In turn, the total system can be recommended for projects that require blocks and reinforcement with higher strengths. The choice between methods must consider project specifications, expected productivity rates and the amount of resources available for structural masonry works.
