1. Recycled gypsum block: development and performance
Resumo O resíduo de gesso ainda é considerado um grave problema econômico e ambiental. Seu volume é alto e sua destinação é muitas vezes inadequada. Visando fornecer uma alternativa mitigatória, esta pesquisa pretende desenvolver blocos que incorporem o resíduo industrial de gesso a partir da logística reversa. Para isso foi realizado um processo d

3. Microstructure and mechanical properties of gypsum composites reinforced with recycled cellulose pulp
The use of waste fibers for the reinforcement of brittle matrices is considered opportune for the sustainable management of urban solid residues. This paper examines the microstructure and mechanical properties of a composite material made of gypsum reinforced with cellulose fibers from discarded Kraft cement bag. Two different kinds of gypsum were used, nat

5. ESTUDO DE ALVENARIAS E REVESTIMENTOS DE GESSO RECICLADO DESTINADO À HABITAÇÃO POPULAR / Study of masonry and Coatings made by Recycled plaster for low cost housing.
The generation of large quantities of solid waste is a great problem faced by urban areas. Like all building materials, the gypsum plaster is a generator of solid waste. The amount and inadequate waste disposal cause serious environmental, social and economical impacts. This requires the search for quick and effective solutions for its management, through th

6. Sistemas logísticos reversos na indústria da construção civil - estudo da cadeia produtiva de chapas de gesso acartonado. / Reverse logistics system in civil construction industry - study of gypsum board chain.
Currently, environmental legislation and pressure of consumer awareness are getting more stringent and restrictive in relation of the proper treatment gave to the industrial wastes. In this context, reverse logistics systems aims to manage the reverse flow, making with that facilities and products with little use after sales, useful life cycle extended or ex

7. Estudo de argamassas com agregados reciclados contaminados por gesso de construção. / A study on mortars produced with CDW recycled aggregates containing cypsum plaster as impurity.
This is an abstract of a Master of Science project carried out at EPUSP, Universidade de São Paulo, Brazil, aimed at investigating the effects of the use of recycled aggregates contaminated by small contents of gypsum plaster on masonry mortars. In the presence of moisture and by the action of gypsum minerals or other more complex ones that may occur, there

8. Effect of Plasterboard Composition on Stachybotrys chartarum Growth and Biological Activity of Spores
The effects of plasterboard composition on the growth and sporulation of Stachybotrys chartarum as well as on the inflammatory potential of the spores were studied. S. chartarum was grown on 13 modified plasterboards under saturated humidity conditions. The biomass was estimated by measuring the ergosterol content of the S. chartarum culture while the spore-
