The lignin was made available by the Suzano Pulp and Paper industry, located in Limeira in the state of São Paulo and the pinus collected in local industries, municipality of Gurupi-TO. Apparent density (g/cm³), axial compressive strength (MPa) and absorption (%) were evaluated for the characterization of the panels. For the preparation of the specimens Portland cement type II (CP II), water, pine and lignin particles and a synthetic additive were used. The pine was subjected to the particle milling and drying process at 8.0% moisture and the lignin was used in the form of particles with 4.6% moisture. After the cement mortar was ready, it was placed in molds made according to NBR 5738 (2003) and D-1037 (1999), and subjected to mechanical vibration compaction. Four treatments were used to make the panels: T1- Cement and Pinus; T2- Cement, Pinus and Lignin; T3- Cement and Lignin and T4 Cement and sand (control). With data generated, the same were submitted to the Bartlett programs to analyze the normality of the variances, Shapiro-Wilk test to test the data normality, Box Cox for data that did not present normality and for statistical analyzes and interaction of the factors used o Sisvar 5.6 O presente trabalho teve por objetivo a produção e caracterização física e mecânica dos painéis compostos por cimento e lignina a fim de compará-los com painéis comumente produzidos visando a possibilidade de sua produção em escala comercial e com isso o reaproveitamento de resíduos produzidos em grandes quantidades. A lignina foi disponibilizada pela indústria Suzano Papel e Celulose, localizada em Limeira no estado de São Paulo e o pinus coletado em indústrias locais, do município de Gurupi-TO. Para a caracterização dos painéis foram avaliados densidade aparente (g/cm³), resistência à compressão axial (MPa) e absorção (%). Para a confecção dos corpos de prova foram utilizados o cimento Portland do tipo II (CP II), água, partículas de pinus e lignina e um aditivo sintético. O pinus foi submetido ao processo de moagem e secagem das partículas a 8,0% de umidade e a lignina foi utilizada na forma de partículas com 4,6% de umidade. Após pronta a argamassa de cimento foi colocada em moldes confeccionados conforme a NBR 5738 (2003) e D-1037 (1999) adaptadas, e submetida a compactação vibro mecânica. Foram determinados quatro tratamentos para confecção dos painéis: T1- Cimento e Pinus; T2- Cimento, Pinus e Lignina; T3- Cimento e Lignina e T4 Cimento e areia (testemunha). Com dados gerados submeteu-se os mesmos aos programas Bartlett para analisar a normalidade das variâncias, teste de Shapiro-Wilk para testar a normalidade dos dados, Box Cox para os dados que não apresentaram normalidade e para analises estatísticas e interação dos fatores utilizou-se o Sisvar 5.6. 2021-10-06T14:08:44Z 2021-10-06T14:08:44Z 2021-10-06 Monografia MEIRELES, Fernanda Kuffel.
