New method to assess the pozzolanic reactivity of mineral admixtures by means of pH and electrical conductivity measurements in lime:pozzolan suspensions
(Inst Ciencias Construccion Eduardo Torroja, 2014-01-01)
A very simple method based on electrical conductivity and pH measurements was proposed for assessing reactivity of pozzolans. Calcium hydroxide: pozzolan water suspensions were monitored by means of measurements of electrical ...
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 ...
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 ...
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 ...
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 ...

Pozzolanic activity of calcined halloysite-rich kaolinitic clays
(Elsevier Science, 2017-10)
The aim of this study is to determine the pozzolanic activity of clays with high content of halloysite/kaolinite, and to evaluate the influence of halloysite/kaolinite ratio and halloysite morphology in the development of ...
Production of agroindustrial ashes with pozzolanic activity via acid leaching, conjugated burning and ultrafine grinding
(ANTAC - Associação Nacional de Tecnologia do Ambiente Construído, 2020)
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 ...
