Thermal analysis to assess pozzolanic activity of calcined kaolinitic clays
(Springer, 2014-04)
The use of calcined clays as partial replacement of cement is encouraged since it promotes the reduction of the green-house gas emission and the energy requirement of cement-based material, maintaining or enhancing the ...
Influence of grinding on the pozzolanic activity of granite residue
(Fundação Gorceix, 2020)
Bagasse ash
(2018-01-01)
Sugarcane (Saccharum officinarum) is the largest crop by production quantity in the world. A large amount of wet bagasse is yielded and the management of this residue is of great importance from an environmental point of ...
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 ...

Avaliação da atividade pozolânica de resíduos agroindustriais em suspensões cal: resíduo
(Universidade Estadual Paulista (Unesp), 2022-02-07)
The construction industry is characterized as one of the biggest consumers of natural resources and non-renewable energy. In the process of manufacturing clinker, an important component of cement, the limestone decarbonation ...
Production of bamboo leaf ash by auto-combustion for pozzolanic and sustainable use in cementitious matrices
(2019-05-30)
In the context of world concern with the environment, this study aims to characterize an auto-combustion produced bamboo leaf ash (BLA) by its pozzolanic behaviour, reactivity and its influence in the total porosity, pore ...
A study of the chemical and physical properties of cashew nut shell ash for use in cement materials.
(UNIV ESTADUAL MARINGA, PRO-REITORIA PESQUISA POS-GRADUACAO, 2010)
A study of the chemical and physical properties of cashew nut shell ash for use in cement materials. Ash occupies a prominent place among agro-industrial wastes, as it is derived from energy generation processes. Several ...
Influência dos óxidos de ferro na reação pozolânica da metacaulinita
(Universidade do Vale do Rio dos Sinos, 2021-12-20)
Pozzolans are materials that react with calcium hydroxide in the presence of water, forming secondary hydrated products and promoting gains in strength and durability in cementitious products. These materials must be ...
