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)
Evolution of the mechanical properties of a tropical soil stabilized with lime and ash of rice rind
(2010-05-01)
The ash of rice rind is a pozzolanic material that reacts with the calcium hydroxide (Ca (OH)2) forming bonding composites, when finely worn out and in water presence. Considering this behavior, the objective of the present ...

Pozzolanic Reactivity Studies on a Biomass-Derived Waste from Sugar Cane Production: Sugar Cane Straw Ash (SCSA)
(2016-08-01)
Biomass has gained in importance as an energy source in recent years. One of the crops that presents interesting opportunities with regard to biomass is sugar cane. In Brazil, sugar cane production is increasing for alcohol ...
Calcined illite-chlorite shale as supplementary cementing material: Thermal treatment, grinding, color and pozzolanic activity
(Elsevier Science, 2019-10)
The thermal transformation (100–1100 °C) of two shales containing illite-chlorite (I/Ch), feldspars and quartz from La Cabañita quarry (Olavarria, Argentine) was studied by TG-DTA, XRD and FTIR. It included dehydration; ...
Study of pozzolanic properties of two sugarcane bagasse ash samples from Honduras
(2016-01-01)
It is well known that the combustion of agricultural waste such as rice husk, bamboo leaf and bagasse among others, depending on the combustion process, may produce powders with pozzolanic properties. Two samples of sugarcane ...
Rice straw ash: A potential pozzolanic supplementary material for cementing systems
(Elsevier B.V., 2017-09-01)
Biomass waste from rice straw has many management problems, including field firing causing severe air pollution and natural organic decomposition resulting in methane emission. The conversion of this waste to ashes may ...
Potential use of Argentine kaolinite clays as pozzolanic material
(Elsevier Science, 2014-11)
Different Argentine kaolinitic clays were selected to study their potential pozzolanic activity. The incidence of several factors such as the origin of deposits (primary or sedimentary clays), mineralogical composition, ...
