Fluid catalytic cracking catalyst residue (FC3R) is a waste material that can be used as a Portland cement replacement in pastes, mortars, and concrete. The flow table results show that FC3R is a water demanding addition; ...

[EN] The recent creation and growth of desktop three-dimensional (3D) printing has led to a new way of building objects. In the manufacture of pieces using Open-Source 3D printing it is very common to use a range of infill ...

The purpose of this aim is to determine the pozzolanic properties, as well as the physical and chemical characteristics of rice straw ash for use as an admixture in concrete mixtures with Portland cement. A material is ...

[EN] The use of geopolymers has revolutionized research in the field of construction. Although their carbon footprint is often lower than that of traditional mortars with Portland cement, activators such as sodium silicate ...

[EN] Alkali activated binders are a new class of binding material with comparable or enhanced performance to Portland cement. These binding materials are obtained by a chemical reaction between an aluminosilicate material ...

[EN] Spent fluid catalytic cracking (FCC) catalyst from the petrol industry has proven to be a very active pozzolanic material. This behavior leads to an additional increase in the strength of the mortar that contains this ...

[EN] The properties of a binder developed by the alkali-activation of a single waste material can improve when it is blended with different industrial by-products. This research aimed to investigate the influence of blast ...

[ES] Esta tesis englobada dentro del programa de doctorado en ingeniería de la construcción sigue la línea de investigación en sostenibilidad y gestión de la construcción. Las investigaciones se han centrado en el desarrollo ...
