Utilización de la goma natural (Leche de Sandy), para elaboración de morteros y enlucidos como sustituto parcial del agua

Abstract

For the execution of the topic raised as the first point, laboratory tests were carried out, such as: Relative density of cement, Fine aggregate particle size, Relative density and absorption capacity of fine aggregate, Volumetric lose weight in order to know the characteristics of the materials and know if it is apt to apply in the investigation. The dosage was then determined according to the data obtained with the laboratory tests, to later execute the samples of mortar and to test to the 28 days of age as indicated in the Ecuadorian Standard of the Construction in section 7. In this way, the samples of mortar with different percentages of Natural Gum (Sandy Milk) that are of 3%, 5% and 8% were partially replaced replacing the water in relation of the cement and the sand, and the adhesion resistance was determined experimentally as Indicates ASTM standard C 952, actual mortar strength as proposed in ASTM C 109 and resistance of masonry prisms as provided in NEC 2015.
