Previous issue date: 2015-12-21 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES) / A demanda por conforto ambiental em sistemas construtivos, no ?mbito da isola??o e conforto t?rmico, somada ao advento de novas leis que regulam os requisitos m?nimos de conforto, as exig?ncias dos consumidores pela ado??o de m?todos de produ??o mais ?limpos?, incentivaram o desenvolvimento do presente trabalho. O mesmo tem como objetivo caracterizar tecnologicamente as mat?rias-primas: res?duo termopl?stico de bot?o e res?duos de gesso para incorporar ao cimento, visando a produ??o de comp?sitos com propriedades de isola??o t?rmica: condutividade, difusividade, capacidade calor?fica e resistividade. As propriedades f?sicas, estruturais e morfol?gicas das mat?rias-primas foram investigadas atrav?s de an?lises de termogravimetria (TG), difra??o de raios X (DRX), fluoresc?ncia de raios X (FRX) e microscopia eletr?nica de varredura (MEV). Os resultados das an?lises indicaram caracter?sticas adequadas para a produ??o de comp?sito de matriz de cimento com adi??o de res?duos industriais termopl?sticos e res?duo de gesso, apresentando potencial de aplica??o destas mat?rias-primas em comp?sitos com propriedades de isola??o t?rmica. / The demand for environmental comfort in construction systems within the insulation and
thermal comfort, plus the advent of new laws regulating the minimum requirements of
comfort, disposal of solid industrial waste, construction waste, the requirements of consumers
by adopting construction methods "cleaner", encouraged the development of this work. Aims
technologically characterize the composite proposed in three types of samples (10%, 30% and
50% of thermoset plastic industrial waste) and raw materials: gypsum waste, cement and
plastic thermosetting industrial waste in order to produce the composite with properties of
thermal insulation: conductivity, thermal diffusivity, specific heat and resistivity. The
physical, structural and morphological properties of the raw materials were investigated by
thermogravimetry analysis (TG / DSC), X-ray diffraction (DRX), X-ray fluorescence (FXR)
and scanning electron microscopy (MEV). Obtaining mechanical properties through the
compression strength test. The analysis results indicate characteristics suitable for cement
matrix composite production with the addition of thermosetting plastic industrial waste and
gypsum waste, with potential application of these materials in composites with properties of
thermal insulation. Finally, assessing what proportion showed up with better performance.
Considering the analysis and testing carried out.
