ABSTRACT In this thesis, the behavior of sawdust was investigated such as particulate material for the construction of masonry units on its compressive strength, slump, absorption and density. Sand was replaced with 0%, 10%, 20%, 30%, 40% and 50% sawdust for each blend design. The concrete was designed for 70 2kg/cm based on Compound Portland Cement Type ICo of the company Pacasmayo, sand and confluence of the quarry “Los Mellizos“ of Huanchaco, a relation water/cement ratio of 0.90 and sawdust of the “Maderera Santana SAC“ located at Miraflores Avenue, Trujillo. Characterization of natural aggregates and sawdust was performed under the Peruvian Technical Standards such as moisture content (NTP 399.185), specific gravity and absorption (NTP 400.022 and NTP 400.021), unit weight (NTP 400.017) and granulometry (NTP 400.012). The cylindrical specimens used were of 10 cm diameter and 20 cm high, cured in a calcium hydroxide solution and assayed at a 28 days (NTP 339.183). The standard NTP 339.034 was used to determine its compressive strength, for its slump the NTP 339.035, and the NTP 339.187 for absorption and density. With the application of the sawdust in the concrete, was produced a concrete for less heavy blocks, but increasing its degree of absorption and, in turn, reducing the slump and its compressive strength. The pattern design or mixture with 0% sand substitution by sawdust achieved a compressive strength of 108 kg/cm 2, a slump of 2 ¾ in, an 3 absorption of 6.1% and a density of 2124 kg/m. The most optimum design for load-bearing concrete masonry units was given at 30% sand substitution by sawdust with a compressive strength value of 72 kg/cm 23, slump of 1 in, 9.5% absorbency and 1916 kg/m density. While for the concrete applied in non-load-bearing concrete masonry units was given at 40% with a 2 compressive strength of 49 kg/cm, slump of ¾ “, absorption of 10.7% and density of 1883 kg/m3.
