Análise do comportamento térmico da pintura de cal com adição de pó de vidro em edificações

Abstract

Concern about the disposal of waste by industries have generated the search for measures that reduce the impact of these materials on nature. Civil construction has sought to take advantage of this type of material to associate with techniques already consolidated to improve their properties. In this context this work adds glass dust to lime for painting. The influence on the temperature variation of prototypes painted with 4 addition proportions (0%, used as reference, 20%, 40% and 60%) on lime paint volume was analyzed. Internal and external temperatures were measured and compared to assess the quality of thermal comfort provided by the inks. The results were satisfactory, all percentages of addition of glass dust favored the decrease of the prototype internal temperature. Among them, the highlight was the addition of 60% of glass powder, which registered a difference of approximately 1 ° C in the internal temperature in relation to the reference.
