Brazilian sugar cane bagasse ashes from the cogeneration industry as active pozzolans for cement manufacture
(ELSEVIER SCI LTD, 2011)
For proper management of wastes and their possible recycling as raw materials, complete characterization of the materials is necessary to evaluate the main scientific aspects and potential applications. The current paper ...
Study of the pozzolanic reaction kinetics in sugar cane bagasse-clay ash/calcium hydroxide system: kinetic parameters and pozzolanic activity
(THOMAS TELFORD PUBLISHING, 2009)
This paper presents a study of the pozzolanic reaction kinetics between calcium hydroxide and a mixture of sugar cane bagasse with 20 and 30% of clay, burned at 800 and 1000 degrees C (SCBCA) by electrical conductivity ...
Pozzolanic behavior of bamboo leaf ash: Characterization and determination of the kinetic parameters
(ELSEVIER SCI LTD, 2011)
The paper presents a characterization and study of the pozzolanic behavior between calcium hydroxide (CH) and bamboo leaf ash (BLAsh), which was obtained by calcining bamboo leaves at 600 degrees C for 2 h in a laboratory ...
Effects of calcining conditions on the microstructure of sugar cane waste ashes (SCWA): Influence in the pozzolanic activation
(ELSEVIER SCI LTD, 2009)
in this paper a study of calcining conditions on the microstructural features of sugar cane waste ash (SCWA) is carried out. For this purpose, some microparticles (< 90 mu m) of sugar cane straw ash and sugar cane bagasse ...
Modelo para la determinación de actividad puzolánica por correlación entre: difractometría, fluorescencia de rayos X y método del cemento
(2014)
Currently one of the main materials for the addition of portland cement is the pozzolan, finely divided material together with the intimate mixture of cement provides cementitious and increases, resulting in a pozzolanic ...
Expansive behavior of an alkali-carbonate reactive dolostone from Argentina: Proposal of an osmotic theory-based model to explain the expansion caused by the alkali attack
(Pergamon-Elsevier Science Ltd, 2020-12)
The expansion mechanism of dolomitic rocks in alkaline environments is complex and a current topic of debate, since two different chemical reactions can coexist: one linked with silica attack (alkali-silica reaction, ASR) ...
