Aplicação de lamas carbonatadas da industria extrativa e transformadora de pedr...
Martins, Ruben; Luis, Lopes; Afonso, Paula; Pires, Vera; Faria, Paula; Mourão, Paulo; Velez, Jorge; Azzalini, AntônioAs lamas carbonatadas (vulgarmente conhecidas por “natas”), resultam do processamento industrial de mármores e/ou calcários explorados no Anticlinal de Estremoz e no Maciço Calcário Estremenho, respectivamente. Tratando-se de materiais homogéneos e relativamente puros (> 95% CaCO 3 ), têm elevado potencial para aplicação industrial pelo que se justifica o estudo da viabilidade técnica e económica de aplicação e...

A Novel Approach for the Reuse of Waste from the Extractive and Processing Indu...
Afonso, Paula; Pires, Vera; Faria, Paula; Azzalini, Antônio; Lopes, Luis; Mourão, Paulo; Martins, RubenThis paper discusses the historical use of natural stone for various purposes and highlights the substantial waste generated by quarries and stone processing plants in modern industrialized production. These waste materials are typically categorized into unused rock and sludges from processing. This accumulation of waste presents a global environmental challenge and a financial burden for the stone industry. In...
Mortar Based on Sludge from Carbonate Dimension Stone Processing Industry - an ...
Afonso, Paula; Azzalini, Antônio; Faria, Paula; Lopes, Luis; Martins, Ruben; Mourão, Paulo; Pires, VeraThe extractive and processing of carbonate dimension stone, such as limestone and marble is particularly important in Portugal. The main extractive centres are in the marble triangle formed by Estremoz, Borba, Vila Viçosa and also the Estremenho Limestone Massif. The large number of quarries and processing units, given the techniques used, both in extraction and processing, and the high-quality criteria require...
Wet and dry conditions influence on natural stone cladding performance with dow...
Pires, Vera; Sitzia, Fabio; Lisci, Carla; Jose, Mirao; Alves, Tiago; Faria, PaulaNatural stone cladding with dowel-pinned anchor systems are commonly used in building façades. Their loading behaviour and mechanical performance in wet and dry conditions is not fully understood, particularly the correlations between the pore structure and the anchorage breaking loads. To answer this concern, a series of breaking load tests on dowel-pinned anchors in both soaked and dry condition were carried ...
Progress for carbon dioxide geological storage in West Macedonia: A field and l...
Tyrologou, Pavlos; Vamvaka, Agnes; Koukouzas, Nikolaos; Pedro, Jorge; Fleury, Marc; Carneiro, Júlio; Ribeiro, Carlos; Ghikas, Dina; Barradas, João PedroBackground: It is widely acknowledged that carbon dioxide (CO2), a greenhouse gas, is largely responsible for climatic changes that can lead to warming or cooling in various places. This disturbs natural processes, creating instability and fragility of natural and social ecosystems. To combat climate change, without compromising technology advancements and maintaining production costs at acceptable levels, carb...

Application of resinous binders with incorporation of carbonated sludges from t...
Afonso, Paula; Azzalini, António; Lopes, Luís; Faria, Paula; Mourão, Paulo; Martins, Ruben; Pires, VeraThe main objective of the Calcinata Project - Production of lime-based mortar from the calcination of carbonated sludge from the ornamental stone industry (marbles and limestone), was to present an alternative use for waste (slurries) from cutting and polishing carbonated ornamental rocks . The industrial application of this waste makes it possible to add value, transforming it into a by-product, thus contribut...
