Efecto de la adición de materiales reciclables en la masilla para construcción liviana respecto a la capacidad calorífica, aislamiento térmico y acústico

Abstract

This paper discusses the results of the experimental research conducted to study the inclusion of recyclable materials such as rice husks, expanded polystyrene (EPS), and polyethylene terephthalate (PET) in joint compound ready mix used for the manufacture of Drywall boards in response to the minimization of the environmental impact and the use of the properties of the discarded materials that are used again in productive processes in order to obtain low thermal conductivity, high heat capacity, high capacity of sound absorption and that it complies with international standards for construction materials, that is why tests were carried out to measure four properties such as Thermal Insulation, Calorific Capacity and Physical-Mechanical Testing (Flexural Resistance and Tensile Strength of Nail) by means of test pieces, taking into account the ASTM C1396 / C1396M - 04 and ASTM C473 - 03, in addition to the acoustic insulation test, ISO 16283-1 of 2014 and ISO 717-1 of 2013 were used. The results obtained were processed using a statistical analysis of multivariate type using Statgraphics Centurion XVII- 2015 software that established the maximum and minimum values, the Pearson correlation and Spearman's ordinal as analysis method for the most efficient material measured the four properties. The rice husk replaces the weight of the gypsum in the original joint compound ready mix putty by 60%, reported the best results in each of the four tests carried out throughout the investigation, thus confirming that it is a suitable material for the implementation In light construction processes, as it demonstrates that recyclable materials are efficient and also possess specific properties such as strength, lightness and flexibility that give added value to be used again and even replace traditional materials.
