1. Mapeamento do processo produtivo e construtivo de alvenaria de tijolo de solo-cimento para habitação de interesse social
RESUMO O assunto sustentabilidade vem crescendo cada vez mais, junto com a necessidade de redução de emissão de gás carbônico por todo o mundo. De modo que projetos, técnicas, e materiais que não prejudiquem o meio ambiente estão ganhando espaço nas pesquisas e nos mercados. Esse trabalho tem como objetivo principal um estudo de caso do processo pro

2. Proposta de modernização em instalação industrial de moagem de escória
This paper presents a proposal for upgrading the mill slag industrial facility in a cement plant, with technology upgrade (retrofit) of the main components of that process, focused on implementation of an automation architecture with remote operation. Currently the installation of this mill still uses the technology of the sixties and is not automated, a sit

3. IMPACTOS E CONFLITOS SÓCIOAMBIENTAIS NA COMUNIDADE DO ENTORNO DA FÁBRICA DE CIMENTO. / IMPACTS AND CONFLICT IN SOCIOENVIRONMENTAL THE SURROUNDING COMMUNITY OF CEMENT FACTORY.
O setor industrial é um dos que mais provoca danos ao meio ambiente, seja por seus processos produtivos ou pela fabricação de produtos poluentes e/ou que tenham problemas de disposição final após sua utilização. Existe uma certa dificuldade em associar o crescimento da produção industrial com a preservação ambiental. O bem-estar coletivo está co

4. Study of the chemical behavior during the ring formation of clinker in cement plant. / Estudo do comportamento quÃmico durante a formaÃÃo de anÃis de clÃnquer em fÃbrica de cimento.
The formation of thick collages in firing zone furnace of clinker in cement plants, called clinker ring, is a phenomenon that creates economical and environmental disorders. To remove the clinker ring it is necessary to cool up the oven for 24 hours cutting it with a breaking machine. This process is dangerous and highly cost-consuming, since the furnace fai

5. Utilização de resíduos da indústria madeireira para fabricação de chapas cimento-madeira / Utilization of the lumber industry for cement-wood particleboard production
A industrialização da madeira gera grande quantidade de resíduos, que são lançados no meio ambiente, e não são aproveitados em sua totalidade, ou quando no máximo são utilizados para geração de energia causando também poluição ambiental. Esta pesquisa teve como objetivo avaliar por meio de ensaios físicos, mecânicos e análise da interface fi

6. Fibre type and concentration in the lungs of workers in an asbestos cement factory.
The predominant asbestos fibre type used in the production of asbestos cement is chrysotile. The use of asbestos in relation to fibre type in a Norwegian asbestos cement plant during 1942-80 was 91.7% chrysotile, 3.1% amosite, 4.1% crocidolite, and 1.1% anthophyllite respectively. Electron microscopy and x ray microanalysis of lung tissue samples of asbestos

7. Exposure to cement dust at a Portland cement factory and the risk of cancer.
The relation between exposure to cement dust and cancer was examined in a population of 546 cement workers and a reference population of 858 randomly sampled men of similar age and area of residence. In 1974 all men gave lifelong occupational and smoking histories; information on incidence of cancer in the period 1974-85 was obtained from the Danish Cancer R

9. Follow up study of workers manufacturing chrysotile asbestos cement products.
A cohort study has been carried out of 2167 subjects employed between 1941 and 1983 at an asbestos cement factory in England. The production process incorporated the use of chrysotile asbestos fibre only, except for a small amount of amosite during four months in 1976. Measured airborne fibre concentrations available since 1970 from personal samplers showed

10. Further follow-up study of workers from an asbestos cement factory.
A further follow-up traced 1970 workers employed at an asbestos cement factory for at least six months between 1936 and 1977. At the beginning of this period some crocidolite was used in the factory but by the end of 1936 chrysotile had become the only type of asbestos in use. Only 378 women were employed during the period concerned, and of the 30 who had di

11. Alterations in the laryngeal mucosa after exposure to asbestos.
The laryngeal mucosa of 195 workers in an asbestos cement factory (Salonit Anhovo, Yugoslavia) and in a control group was examined. The factory manufactures asbestos cement products containing about 13% of asbestos (8% amosite, 12% crocidolite, and 80% chrysotile) of different provenance. Alterations in the laryngeal mucosa were more frequent in the factory

12. Mortality among long-term employees of an Ontario asbestos-cement factory.
Mortality was studied among a group of 328 employees of an Ontario asbestos-cement factory who had been hired before 1960 and who had been employed for a minimum of nine years. The group of 87 men who had worked in the rock wool/fibre glass operations, or who had been otherwise minimally exposed to asbestos, had mortality rates similar to those of the genera
