1. Efeito do envelhecimento acelerado sobre as propriedades de microconcreto reforçado com fibras longas de sisal
Resumo Neste trabalho dois microconcretos, com e sem metacaulinita, foram dosados para produção de compósitos laminados reforçados com fibras longas de sisal. Para garantir uma matriz livre de hidróxido de cálcio foi determinado o teor ideal de metacaolinita por análise termogravimétrica de pastas com teores de substituição de 20%, 30% e 40 nas ida

2. Hybrid composites reinforced with short sisal fibres and micro ceramic particles
ABSTRACT Biocomposites reinforced with natural fibres have been extensively investigated as a promising replacing material for synthetic ones, such as the glass fibre reinforced composites. The length of natural fibres depends not only on the plant species, but also on the extraction processing. The heterogeneity of natural fibres, in terms of length, can be

3. Tensile Behaviour and Durability Issues of Engineered Cementitious Composites with Rice Husk Ash
ABSTRACT The Engineered Cementitious Composites (ECC) is a special type of High Performance Fibre Reinforced Cementitious Composite (HPFRCC) characterized by a high tensile ductility with a 2% maximum volume of micro fibres. ECC has a tensile strain-hardening performance that leads to multiple cracking behaviour, thus providing the high ductility to the conc

4. Compressive stress-strain behaviour of cement mortar-composites reinforced with short sisal fibre
To design building elements using sisal fibre reinforced mortar composites, the stress-strain curves of the composites both under tensile and compression load is needed. In this study short sisal fibre-cement based composites were developed and their stress-strain behaviour under compression characterized experimentally. The composites consisted of two morta

5. Cement - steatite composites reinforced with carbon fibres: an alternative for restoration of brazilian historical buildings
Steatite is a mineral which has been employed in the carving of elements in facades of Brazilian historical buildings and churches since the 17th century. Over the years, many of those historical buildings suffered the consequences of weathering with a current need for restoration. Recently a special cement-based mortar containing additions of fine powder wa

6. Contribuição ao estudo das propriedades dos materiais cimentícios reforçados com fibras de vidro (Glass Fibre Reinforced Cement - GRC) / Contribution to the study of properties of glass fibre reinforced cement - GRC
Os materiais cimentícios são materiais frágeis que apresentam resistências à tração e capacidades de deformação muito baixas. Uma das formas de contornar a fragilidade destes materiais é a utilização de fibras curtas, descontínuas e dispersas. Um exemplo destes materiais cimentícios são os produzidos com fibras de vidro, comumente denominados

7. CEMENTITIOUS COMPOSITES REINFORCED WITH CURAUÁ FIBERS / COMPÓSITOS CIMENTÍCIOS REFORÇADOS COM FIBRAS DE CURAUÁ
A busca por materiais alternativos que possam substituir as fibras de amianto, compondo o fibro-cimento, tem-se tornado objeto de estudos recorrentes. As fibras vegetais surgem como opção econômica, salubre e ecologicamente adequada. O objetivo deste trabalho foi estudar o comportamento da adição da fibra de curauá em compósitos cimentícios, visando

8. COMPOSITE MATERIALS REINFORCED WITH NATURAL FIBRES: EXPERIMENTAL CHARACTERIZATION / MATERIAIS COMPÓSITOS REFORÇADOS COM FIBRAS NATURAIS: CARACTERIZAÇÃO EXPERIMENTAL
This thesis studies both the short-term and long- term behaviour of sisal and coconut fibre reinforced mortar composites.The experimental work involved extensive laboratory testing to determine the physical and mechanical properties of the fibre reinforcement and to study the influence of fibre type, volume fraction, fibre length, fibre arrangement and matri
