Adição de geomanta e tecido não tecido de polipropileno em cimentos geopoliméricos de pega rápida
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia MecânicaTecnologia de Materiais; Projetos Mecânicos; Termociências, 2008-06-05)
Geopolymers are cementing materials that depict a number of advantages compared to Portland cement. Contrary to the latter, geopolymers are synthesized at room temperature,
thus significantly reducing the emission of CO2 ...
New geopolymeric binder based on fluid catalytic cracking catalyst residue (FCC)
(Elsevier B.V., 2014)
Desenvolvimento preliminar de uma argamassa colante geopolimérica
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2019-12-04)
The advance of civil construction, linked to the growth of the ceramic products market, stimulates the production of adhesive mortars that are used in settling ceramic plates. NBR 14081-1 (ABNT, 2012) classifies mortars ...

Obtenção de geopolímero a partir de metacaulim ativado
(Universidade Federal de Minas GeraisUFMG, 2013-07-23)
The use of supplementary cementitious materials alkali-activated has showed an economically viable alternative that greatly contributes to minimizing environmental impact. Among these materials geopolymers stand out as ...
Preparação do adsorvente magnético geopolímero/ferro metálico para remoção de contaminante orgânico em efluente aquoso
(Universidade Federal de Santa MariaBrasilEngenharia QuímicaUFSMPrograma de Pós-Graduação em Engenharia QuímicaCentro de Tecnologia, 2019-07-31)
In this work the synthesis of a magnetic geopolymer from silica, metakaolin, iron zero-valent, soybean oil, sodium hydroxide and hydrogen peroxide was proposed. The magnetic geopolymer was characterized by X-ray diffraction, ...
Avaliação dos agregados de resíduos da construção civil em matriz geopolimérica visando aplicação em pisos intertravados
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2022-04-14)
The production of Portland cement (PC) is seen as aggravating the environment,
so scientists and engineers look for alternatives to replace this type of binder.
Geopolymers have the potential to replace CP, as it aims ...
Influence of processing parameters variation on the development of geopolymeric ceramic blocks with calcined kaolinite clay
(2022-06-01)
The cement industry is responsible for a considerable part of the emission of gases that cause the greenhouse effect. In this context, geopolymer materials have been the subject of extensive studies, as they are an ...
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 ...
