Lime based mortars for ceramic tile application: the influence of the lime, the...
Faria, Paulina; Silva, Vitor; Grilo, J.; Bandeira, A.; Branco, T.; Mergulhão, D.Intern.Conference AZULEJAR, Univ. Aveiro, 10-12 October 2012 ; Bearing in mind the need to repair ceramic tile facade, that were traditionally applied by a lime-based mortar, an experimental campaign was held in order to characterize over time mortars made with two types of lime - an air lime EN 459-1 CL90-S and a recently classified EN 459-1 NHL3.5. The influence of different binder: aggregate proportions on ...
Proportion, composition and potencial N mineralisation of particle size fractio...
Fangueiro, D.; Gusmão, M.; Grilo, J.; Porfirio, G.; Vasconcelos, E.; Cabral, F.Research Paper ; Mechanical slurry separation is a useful technology for slurry management on farms. The characteristics of the fractions obtained depend on the separation efficiency and on the characteristics of the original slurry. In the present work, three types of slurry e pig, cow and duck e were separated into 4 particle size fractions. The proportion, composition in terms of carbon and nutrients as nit...
Influence of the particle size and animal slurry type on the potential of nitro...
Fangueiro, D.; Gusmão, M.; Grilo, J.; Vasconcelos, E.; Cabral, F.RAMIRAN International Conference ; Animal manures are rich in organic matter and nutrients, namely nitrogen (N) and, consequently, widely applied to soil as organic fertilizers. However, a large part of the nitrogen contained in animal manures is in the organic form and so not directly available for plants. Indeed, organic N has to be mineralized prior to plant uptake (Rees and Castle, 2002). Several manure ch...
Análise da evolução de uma área da Península de Setúbal na sequência de um proc...
Quinta-Nova, L.C.; Fernandes, J.P.A.; Baptista, P.; Cruz, C.S.; Teles-Grilo, J.O objectivo do estudo foi testar métodos de análise ambiental que permitam analisar o efeito de tipologias específicas de perturbação de modo a permitir a sua utilização prospectiva no processo de planeamento e gestão do território. Para tal procedeu-se à análise em termos de usos e funções ecológicas a evolução de uma área de características sub-regionais, localizada na Península de Setúbal. Trata-se de uma fa...
