Comparative effects of different real conditions in the microstructure and properties of ternary blended cement mortars for being used in rehabilitation works

Ortega, José Marcos; Ibáñez-Gosálvez, Javier; Real-Herraiz, Teresa Pilar (Elsevier, 2023-04)

[EN] The use of ternary binders in commercial cements is very low, at least in Spain. A possible field of application of these ternary cements would be the rehabilitation of coatings of old buildings, whose performance may ...
Effects after 1500 Hardening Days on the Microstructure and Durability-Related Parameters of Mortars Produced by the Incorporation of Waste Glass Powder as a Clinker Replacement

Tremiño, Rosa María; Real-Herraiz, Teresa Pilar; Letelier, Viviana; Branco, Fernando G.; Ortega, José Marcos (MDPI AG, 2021-04)

[EN] One of the ways of lessening the CO2 emissions of cement industry consists of replacing clinkers with supplementary cementitious materials. The required service life of real construction elements is long, so it is ...
Microstructure and Durability Performance of Mortars with Volcanic Powder from Calbuco Volcano (Chile) after 4 Hardening Years

Tremiño, Rosa María; Real-Herraiz, Teresa Pilar; Letelier, Viviana; Ortega, José Marcos (MDPI AG, 2021-04)

[EN] One of the most popular ways to lessen the impact of the cement industry on the environment consists of substituting clinker by additions. The service life required for real construction elements is generally long, ...
Microstructure and mechanical properties of ternary mortars with brick powder, glass powder, slag, fly ash, and limestone

Tremiño, Rosa María; Real-Herraiz, Teresa Pilar; Letelier, Viviana; Ortega, José Marcos (Blackwell Publishing, 2022-07)

[EN] The objective of this research is to study the effects produced by ternary binders which combine the addition of waste brick powder with fly ash, limestone, ground granulated blast furnace slag or waste glass powder ...
Microstructure, Durability and Mechanical Properties of Mortars Prepared Using Ternary Binders with Addition of Slag, Fly Ash and Limestone

Ibáñez-Gosálvez, Javier; Real-Herraiz, Teresa Pilar; Ortega, José Marcos (Springer, 2021-07)

[EN] In order to improve the contribution to sustainability of cement production, several strategies have been developed, such as the incorporation of additions as clinker replacement. Regarding the production of commercial ...
Performance of Mortars Made Using Ternary Binders with Addition of Slag, Fly Ash and Limestone Exposed to a Real Environmental Condition Compatible with Exposure Class XC3

Ibáñez-Gosálvez, Javier; Real-Herraiz, Teresa Pilar; Ortega, José Marcos (MDPI AG, 2021-10)

[EN] The use of eco-friendly cements prepared with ternary binders could contribute to improving the sustainability of cement production. However, their use for manufacturing commercial cements is very low, at least in ...
Use of Volcanic Powder as a Cement Replacement for the Development of Sustainable Mortars

Letelier, Viviana; Ortega, José Marcos; Tremiño, Rosa Maria; Henriquéz-Jara, Bastián I.; Fustos, Ivo; Real-Herraiz, Teresa Pilar; Moriconi, Giacomo; Climent, Miguel Ángel; Sánchez, Isidro (MDPI AG, 2020-02)

[EN] Currently, reduction of environmental effects of the cement industry is an issue of global interest and one of the alternatives is to replace clinker with additions such as volcanic powder. The purpose of this work ...
