Ternary Blends of White Cement, Limestone, and Waste Glass for 3D Printing

Abstract This work focuses on the development of white formulations for 3DPC, a characteristic rarely addressed in the literature but relevant for architectural applications. The 3DPC was developed based on an integrative design to reach carbon-efficient white ternary blends for 3DPCC, reflecting engineering and environmental balance. A central composite design (CCD) was followed to identify statistical models capable of describing key properties of ternary...

Toward Sustainable Cooling: A Comprehensive Perspective on Replacing Synthetic Refrigerants with Natural Refrigerants

Formulações ternárias de cimento, filler calcário e resíduos de vidro moído para impressão 3D

O presente estudo, realizado no âmbito do Projeto DigiCrete, teve como objetivo desenvolver formulações ternárias eficientes em carbono para impressão 3D de materiais cimentícios (3DPC). A sustentabilidade das fórmulas baseou-se em três aspetos principais: a utilização de matérias-primas nacionais, a substituição parcial significativa do cimento Portland (> 50%) e a otimização do teor de cimento. Numa primeira fase, estudaram-se as propriedades das pastas cimentícias, avaliando o comportament...

Soil-geosynthetic inclined plane shear behavior: influence of soil moisture content and geosynthetic type

This paper deals with the inclined plane shear on three different geosynthetics (a geocomposite (GC), a non-woven geotextile (GTX), and an extruded geogrid (GGR)) with a residual soil from granite. Soil and geosynthetic properties, test equipment, and procedures are described. The influence of soil moisture content and geosynthetic type on soil - geosynthetic interaction behavior is discussed by analyzing the results of the inclined plane shear tests. The main conclusions that can be outlined...
