1. Experimental investigation on the effects of recycled aggregate on fracture behavior of polymer concrete
The sustainable management of solid wastes stimulates metallurgic and metal mechanics industries to look for safety applications for these wastes. The present paper examines the fracture behavior of polymer concrete (PC) manufactured with recycled foundry waste in substitution of fresh one. The recycled foundry sand is contaminated with polymer resin from th

2. Desenvolvimento e avaliaÃÃo da tecnologia de produÃÃo de Ãsteres homogÃneos de sacarÃdeos por acetilaÃÃo catalÃtica
As part of the systematic study of the process of acetylation of saccharides aiming to obtain products of industrial interests, we did tests with monosaccharides (glucose and fructose), disaccharides (sucrose). The sucrose composing abundant raw material deserves special attention as reagent acetylation of departure for a homogeneous environment. In the pres

3. PHOTOPLASTICITY BEHAVIOR OF POLYESTER RESINS UNDER AND AFTER LOADING / FOTOPLASTICIDADE EM MODELOS DE RESINA POLIÉSTER SOB CARREGAMENTO E APÓS DESCARREGAMENTO
Três tipos de resinas poliéster comercializadas no mercado brasileiro foram analisadas em modelos sob carregamento e após descarregamento para diferentes estados de tensões e deformações, visando sua aplicação em fotoplasticidade. As resinas Leoglass 130PA e Polylite T-208 tiveram seu comportamento mecânico a comportamento mecânico a compressão av

4. Caracteristicas do poliester reforçado com fibra de vidro para aplicações em coletores solares termicos
The use of solar collectors, flat-plate or focusing, is growing fast. The use of plastic materials is becoming more popular, more particularly in the use of fiberglass reinforced polyester. How ever, little is known about the limitations of the material with respect to the outside exposure. The purpose of this work is to characterize fiberglass reinforced po

5. Polyester Resin Hazards
Polyester resins are being increasingly used in industry. These resins require the addition of catalysts and accelerators. The handling of polyester resin system materials may give rise to skin irritations, allergic reactions, and burns. The burns are probably due to styrene and organic peroxides. Atmospheric pollution from styrene and explosion and fire ris

6. A cohort mortality study and a case-control study of workers potentially exposed to styrene in the reinforced plastics and composites industry.
The cohort consisted of 15,908 men and women who worked for at least six months between 1948 and 1977 in 30 participating manufacturing plants in the reinforced plastics and composites industry. These workers were occupationally exposed to the working environment in the industry, which included exposure to styrene. Cause specific mortality analyses were perf
