Use of phase change materials microcapsules in aerial lime and gypsum mortars

Presently, the concerns related to the buildings energy consumption are greater, emerging in this way the need to incorporate materials in the construction products which aim the improvement of the energetic efficiency f buildings. Therefore, the application of phase change materials appears as a possible solution in an attempt to solve, or at least minimize, the massive energetic consumption related with build...

Properties of lime based thermal mortars

Cincos 2010 : Congresso de Inovação na Construção Sustentável

Argamassas funcionais para uma construção sustentável

A necessidade de responder às exigências da construção sustentável tem originado o desenvolvimento de novos materiais e a transformação de outros, com o objectivo de acompanhar a evolução deste sector. A sustentabilidade dos edifícios não se calcula apenas pela avaliação do seu impacto ambiental. Outros aspectos têm que ser considerados, como por exemplo, o conforto dos ocupantes, a qualidade do ar interior e o...

Fresh state characterization of lime mortars with PCM additions

The application of sustainability principles in construction encourages the development of new products, with new functionalities and applications, able to improve buildings environmental performance. The use of latent heat storage materials in lime mortars aims to reduce the energy consumption of buildings. This work intends to evaluate the impact of phase change materials (PCM) incorporation in rheological an...

Rehabilitation mortars for zero-impact buildings

The selection of construction materials represents a Key step in any zero-impact building project. These materials account for several environmental impacts during their life cycle, and a significant part results from operational energy consumption. The need for new solutions which improve the environmental performance without compromising the buildings interior comfort, has emerged. In recent years, new materi...

Application of latent heat thermal energy storage in cement mortars

Using Phase Change Materials (PCM) for thermal energy storage is an effective solution both for more efficient use of energy and its consumption reduction. The needs of heating and cooling systems can be reduced with the adequate use of PCM. The objective of this study was the development of new interior cement mortar with thermal enhanced properties by incorporating microencapsulated PCM. The compositions were...

Bibliografia do bacuri (Platonia insignis Mart.).

O bacurizeiro é uma árvore mitífera e madeireira, pertencente a família Clusiaceae, tendo como provável centro de origem o Estado do Pará, atingindo também os Estados do Maranhão, Tocantins e Piaui. Apresenta grande plasticidade ecológica, ocorrendo nas florestas do Pará e cerrados do Piauí. O fnito apresenta grande potencial para os mercados interno e externo, em função das características organolépticas de su...
