Diseño experimental comparativo entre el bloque de hormigón y bloques con agregados alternativos aplicando la Norma Técnica Ecuatoriana INEN 3066.

Abstract

The purpose of this titling work is to create new alternatives in the field of construction materials, which is why this work presents a new alternative for dosing, preparation and analysis with eco-friendly materials with the purpose of generating a new proposal to society and allowing a better sustainable and sustainable development with the purpose of improving the quality of masonry for construction and helping to improve our planet earth. The comparative analysis that was applied in this project were the concrete blocks and the new blocks with alternative aggregates such as sawdust and banana stem fiber. These elements such as sawdust were obtained directly from the Buena Fé Bloquera and the fiber of the banana stem was acquired at the Bene Estate Both places are located in the Machala Canton to know and verify if the blocks with the two types of alternative aggregates comply with the resistance as established in the Ecuadorian Technical Standard NTE of the Ecuadorian Standardization Service INEN 3066. For the dosing and the elaboration of the blocks with alternative aggregates, it was carried out according to the dosage corresponding to the Buena Fe Bloquera, which is located on Av. La Ferroviaria, in front of Juan Pablo II Avenue, and the traditional block was used with measures of 40 cm 20 cm 7 cm without hole; therefore, the material to be replaced is the chasqui with which it was replaced with 2, 4, 6, 8 and 10 of each alternative material such as sawdust and banana stem fiber, where 4 specimens of each alternative material were made to carry out the tests corresponding to the compression, absorption and density corresponding to 7 days, 14 days and 28 days. In accordance with the provisions of the Ecuadorian Technical Standard INEN 3066 establishes the 3 types of resistance for the three blocks that were tested and also the type of classification to which the specimen belongs; for this, according to the results of the tests carried out in the laboratories of the School of Civil Engineering and as established, the following is known, at 28 days the concrete block of the Buena Fe Bloquera obtained a resistance of 2.0 MPa the sawdust block with a percentage of 2 achieves a resistance 2.9 MPa. For the sawdust block with 4, a resistance of 2.2 MPa is achieved, being optimal for its use and use.
