Abstract: In this work the performance of gypsum plaster and wood particle in pastes and composites was investigated. Wood particles of fineness 0.42 mm and 1.20 mm were employed. Natural wood particles and the treated ones in cold or hot water (80 °C) were performed. The effects of the extractives solutions from the treatments applied to the wood particles on wood-gypsum compatibility were studied. For pastes and composites, waterto-gypsum ratio was 0.65. Wood particles-to-gypsum plaster ratios were 5%, 10% and 15%, in… Show more

“…Hence, these boards do not have strong impact resistance for some building applications. These situations can be partly overcome by combining gypsum with various types of natural fibers (waste paper, agriculture waste fibers) to impinging better mechanical performance [15,16]. Some advantages and disadvantages of gypsum-based composite materials are given in Table 2.…”

“…O resíduo de gesso apresentou uma granulometria maior que o gesso comercial (Tabela 2), logo a taxa de hidratação aumenta com a redução do tamanho das partículas devido a maior área específica do grão, pois o processo de hidratação inicia em sua superfície externa [37,25].…”

“…O gesso pode ser usado na forma natural com crescimento intenso na construção civil e calcinado amplamente utilizados em edifícios, cerâmica e indústrias médicas [1][2][3]. Geralmente o resíduo de gesso está disponível em forma de pó, torrões ou pedaços provenientes de produtos como chapas para drywall e placas, logo para a sua reutilização é necessário triturar, moer e peneirar [4].…”

“…Several treatments of wood chips are proposed in the literature to solve the problems associated with their chemical interaction with the hydraulic binder and swelling. These include treatment with cold or hot water [97,106,109,111], coating with hydraulic lime or linseed oil [106], and thermal treatment by mild pyrolysis under a nitrogen atmosphere [102,104,108].…”
