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 ...

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 ...

Pozzolanic activity quantification of hollow glass microspheres
(Elsevier, 2021-04)
Hollow glass microspheres (HGMS) have been widely used in the hydrocarbon industry for cementing wells with low-density slurries. These consist of amorphous siliceous hollow spheres filled with gas, providing a low-density ...
Use of ceramic sanitaryware as an alternative for the development of new sustainable binders
(2016-01-01)
Large amounts of ceramic sanitary-ware waste are generated in both the production process and construction and demolition practices. This waste contains amorphous phases that may react with the Portlandite that originates ...
Production of bamboo leaf ash by auto-combustion for pozzolanic and sustainable use in cementitious matrices
(2019-05-30)
In the context of world concern with the environment, this study aims to characterize an auto-combustion produced bamboo leaf ash (BLA) by its pozzolanic behaviour, reactivity and its influence in the total porosity, pore ...
