ABSTRACT The present research seeks to compare the compressive strength of a cement-sand mortar (1: 3 and 1: 4) by replacing different percentages of river sand with sand dune (10 and 20%). For this the physical properties of the river and dune sands have been analyzed as they are moisture content (W = 5.90% for the river sand and W = 1.03% for the sand of dune), granulometry (MF = 2.33 for the sand (PUSS = 1.70 and PUCS = 1.82 g/cm3 for river sand and PUSS = 1.38 g/cm3 and PUCS = 1.57 g/cm3 for the sand dune), specific weight and percentage of absorption that served to design the mortar, in addition a chemical study of aggressive salts to the dune sand was carried out to determine the amount of chloride and sulfates it contains; consequently the test tubes were made and tested in compression resistance at 3, 7 and 28 days of curing. With the research it was determined: for the 1: 3 cement-sand dosage with replacement of 10% of sand dune the resistance decreases in 6.88% and with replacement of 20% of dune sand the resistance decreases in 7.70%; for the 1: 4 cement-sand dosage with 10% sand dune replacement the resistance decreases by 3.13% and with a 20% sand dune replacement the resistance decreases by 9.20%.
