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 ...
Use of high-resolution thermogravimetric analysis (HRTG) technique in spent FCC catalyst/Portland cement pastes
(Springer, 2015-06-01)
Thermogravimetric analysis is one of the most common instrumental techniques used for the characterization of pastes, mortars and concretes based on both calcium hydroxide and Portland cement. Important information about ...
Effect of metakaolin pozzolanic activity in the early stages of cement type II paste and mortar hydration
(2008-04-01)
The cement industry is one which most emits polluting gases to the environment, due to the calcium carbonate calcination, as well as to the burning of fossil fuels during the manufacturing process. Metakaolin (MK), in ...
Valorisation of sugarcane bagasse ash (SCBA) with high quartz content as pozzolanic material in Portland cement mixtures
(2018-04-01)
Portland cement (OPC) production is one of the most contaminating greenhouse gas producing activities. In order to reduce OPC consumption, several alternatives are being assessed, and the use of pozzolanic material is one ...
Improving the reactivity of a former ground sugarcane bagasse ash produced by autogenous combustion through employment of two different additional grinding procedures
(2021-02-08)
Studies on reactivity of sugarcane bagasse ash (SCBA), obtained by an autogenous combustion process, with low loss on ignition and three different particle sizes were carried out (SCBA-1, SCBA-2 and SCBA-3). The ashes were ...
Biomass-Derived from Bamboo Leaf Ash: Pozzolanic Reactivity
(Materials Research Forum Llc, 2018-01-01)
Bamboo leaf ash (BLA) was assessed as a pozzolanic material in pastes and mortars. Differently from most of research performed, the BLA studied in this paper was obtained through an auto-combustion process. This material ...
Influência da adição de cinza do bagaço de cana calcinada em sistemas de pastas para cimentação de poços petrolíferos
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia do PetróleoPesquisa e Desenvolvimento em Ciência e Engenharia de Petróleo, 2014-01-31)
Cementing operation is one of the most important stages in the oil well drilling processes and has main function to form hydraulic seal between the various permeable zones traversed by the well. However, several problems ...
Determinación de la reactividad puzolánica de adiciones minerales de origen natural con el cemento Portland
(2008-10-07)
RESUMEN: México posee fuentes importantes de materiales de origen volcánico, los cuales pueden ser utilizados como puzolanas naturales para reemplazar cemento Portland en la industria de la construcción. Sin embargo, la ...
