Diseño de un bloque alivianado utilizando poliestireno expandido, PET, vermiculita como agregados

Abstract

In recent years, the use of recyclable waste has been gaining ground in the field of construction, since the generated waste can be revalued and reduce the impacts that this waste can cause in the environment, without reducing the quality of the constructions. For this reason, the present research work has the objective of designing a lightened block by adding expanded polystyrene, PET, vermiculite to the mortar mixture to differentiate cost-benefit from the traditional market, applying an experimental methodology with a quantitative approach, since it was developed tests to determine the adequate dosage for lightened blocks, and tests of simple compression, absorption, and bibliographic analysis of shrinkage tests by linear drying, visual aspects and marks and resistance to fire. Four tests were carried out on blocks with different dosages, of which the fourth test was optimal for lightened blocks with a dosage of 20% expanded polystyrene, PET, vermiculite. In addition, modulus of rupture values ​​of 9.57 MPa, 9.53 MPa and 9.48 MPa were obtained, in the maximum time of 28 days, the economic and environmental analysis was carried out in comparison with a traditional block. It is concluded that, based on the results, the dosage of block No. 4 is adequate for the elaboration of the lightened blocks, since the tests show that they are within the requirements of the Ecuadorian Construction Standard.
