Sulfate performance of calcined illitic shales
(Elsevier, 2021-07)
In the past, calcined pozzolans were largely used in massive concrete, and nowadays, they appear as an excellent alternative to reduce the clinker factor in general use cement. The pozzolanic activity of two calcined illitic ...
Performance of Self-Compacting Concrete with Residue of Masonry and Recycled Aggregate under Sulfate Attack
(American Society of Civil Engineers, 2024)
The use of byproducts as supplementary cementitious materials (SCMs) and recycled coarse aggregates (RCAs) can contribute tothe production of more sustainable self-compacting concrete (SCC) while modifying the durability ...
Durabilidade de argamassas submetidas ao ataque de sulfatos : efeito da adição da nanosílica
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Civil - PPGECivCâmpus São Carlos, 2018-03-28)
Durability is one of the characteristics to be considered in design and projects of concrete structures as it is related to the useful life of buildings. Among the aggressive agents most damaging to the concrete are sulfate ...
Long-term sulfate attack on recycled aggregate concrete immersed in sodium sulfate solution for 10 yearsAtaque por sulfatos a largo plazo sobre hormigón de árido reciclado sumergido en solución de sulfato de sodio por 10 años
(Instituto de Ciencias de la Construcción Eduardo Torroja, 2020-02)
The effect of recycled concrete aggregate (RCA) on concrete performance against external sulfate attack (ESA) is not yet fully known. In this paper, recycled aggregate concretes (RAC) with 0, 50, 75 and 100% of RCA contents ...
Comportamento do cimento álcali ativado quando exposto ao ataque combinado de sulfatos
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilPrograma de Pos-Graduação em Engenharia CivilUTFPR, 2022-08-30)
Alternative cements to Portland cement have been widely studied in the field of civil construction in order to mitigate the environmental effects produced by this conventional binder. In this context, activated alkali ...
External sulphate attack on recycled concrete: Assessment of the influence of recycled aggregate
(Springer, 2020)
The performance of recycled aggregate concrete (RAC) under external sulfate attack (ESA) has not been fully clarified yet. The attached mortar on recycled aggregate particles increases the content of hydration products ...
Comportamento do cimento supersulfatado (CSS) exposto ao ataque por sulfatos de origem externa
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilPrograma de Pos-Graduação em Engenharia CivilUTFPR, 2020-02-10)
Portland cement (PC) is one of the most used construction materials in the world and draws attention due to the high amount of carbon dioxide emitted in its production. In this sense, supersulfated cement appears as an ...
