High strength mortars using ordinary Portland cement-fly ash-fluid catalytic cracking catalyst residue ternary system (OPC/FA/FCC)
(2016-03-01)
The use of ternary systems composed of ordinary Portland cement (OPC) and two pozzolanic mineral admixtures could supply several advantages in terms of the properties in both fresh and hardened states. Fly ash (FA) and ...
Assessment of sugar cane straw ash (SCSA) as pozzolanic material in blended Portland cement: Microstructural characterization of pastes and mechanical strength of mortars
(2015-07-21)
Abstract The aim of this paper is to assess the pozzolanic reactivity of sugar cane straw ash (SCSA) obtained through an auto-combustion process and the mechanical properties of SCSA-containing systems. Characterization ...
Characterization and properties of elephant grass ashes as supplementary cementing material in pozzolan/Ca(OH)(2) pastes
(Elsevier B.V., 2014-12-30)
This work presents the behavior of two elephant grass ashes, as pozzolans, elephant grass cameroon (EGC) and napier (EGN), calcined under controlled conditions (700 degrees C). The ashes were initially submitted to a ...
Estudo da álcali-ativação de pó de blocos cerâmicos com cal hidratada
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia CivilUTFPR, 2017-04-26)
Ceramic materials from bricks and tiles present in construction waste are considered contaminants in the production of recycled aggregates, as they have a low compressive and impact strength, as well as high porosity. These ...

Determinação da atividade pozolânica da cinza de bagaço de cana-de-açúcar comparada à sílica amorfa e cristalina
(Universidade Federal de Minas GeraisUFMG, 2015-09-18)
The objective of this study is to determine if it is possible to establish a pozzolanicity scale that correlates the results of different direct and indirect tests using highly reactive additions (silica fume) and less ...
Estudo da captura de dióxido de carbono por misturas de hidróxido de cálcio e óxido de magnésio em baixas temperaturas
(Universidade Federal de Minas GeraisUFMG, 2012-02-24)
The present work has studied the carbonation reaction of hydrated lime modified by small percentages of magnesium dioxide (MgO) by the carbon dioxide (CO2) from the exhaust gas of a petrol engine. For this purpose, spherical ...
