Influência da adição de diatomita nas propriedades de pastas geopoliméricas: volume de filtrado, tempo de espessamento e resistência à compressão
(ABCERAM, 2015-09)
Today, the diversity of available materials for use in engineering is very large, resulting in an increasing of specific materials for each type of application. The geopolymers have been studied for various decades. They ...
Evaluation of the long-term compressive strength development of the sewage sludge ash/metakaolin–based geopolymer
(2021-07-28)
This paper aimed to evaluate the long-term compressive strength development of the sewage sludge ash/metakaolin (SSA/MK)–based geopolymer. SSA/MK–based geopolymeric mortars and pastes were produced at 25ºC with different ...

(Universidad Nacional de ColombiaMedellín - Arquitectura - Maestría en ConstrucciónEscuela de ConstrucciónFacultad de ArquitecturaMedellínUniversidad Nacional de Colombia - Sede Medellín, 2012-11-26)
Este trabajo busca aplicar el proceso de geopolimerización al bloque de suelo cemento (BSC), para obtener un bloque de suelo geopolimerizado (BSG), ya que la producción del primero, estabilizado con cemento y compactado ...
Influência da cura térmica em geopolímeros à base de metacaulim
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosEngenharia Civil - ECiv, 2023-03-24)
Geopolymers are an alternative that has been proving interesting compared to the use of Portland cement due to the potential reduction of greenhouse gas emissions in the production of the material. However, its physical ...
Mechanical and thermal performance of a geopolymeric and hybrid material based on fly ash
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2016-01-01)
This article presents an evaluation of the thermal behavior of a hybrid (FA/OPC) and geopolymer (FA100) material. The FA100 system is based on fly ash (FA), which has an elevated content of unburned material (14.8%). The ...
Influência da adição de diatomita em pastas geopoliméricas para poços de petróleo
(Universidade Federal do Rio Grande do NorteBrasilUFRNPrograma de Pós-Graduação em Ciência e Engenharia de MateriaisCentro de Ciências Exatas e da Terra, 2012-07-26)
Cementation is a common practice in the oil industry, and have fundamental importance in
building a oil well. The development of this activity has promoted the search for suitable
materials for cementing oil wells, seeking ...
Otimização e análise mecânica de pastas geopoliméricas para uso em poços sujeitos à injeção cíclica de vapor
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia de MateriaisProcessamento de Materiais a partir do Pó; Polímeros e Compósitos; Processamento de Materiais a part, 2008-10-28)
Oil wells subjected to cyclic steam injection present important challenges for the development of well cementing systems, mainly due to tensile stresses caused by
thermal gradients during its useful life. Cement sheath ...
