Analysis of thermal process of pozzolan production
Materiales de Construccion, 2004 The objective of this study was evaluated the effect of heat treatment parameters on the pozzolanic activity of natural kaolin clays. The experimental design included three factors: kaolin type, temperature and time.

Use of gypsum and bagasse ash for stabilization of low plastic and high plastic clay
Journal of Applied Research on Industrial Engineering, 2019 Clays have a tendency to undergo volumetric changes when they interact with water. These soils are a very common reason for most of the foundation failures due to their degraded properties.

Evaluation the pozzolanic reactivity of sonochemically fabricated nano natural pozzolan
Ultrasonics Sonochemistry, 2012 Natural pozzolans are appropriate supplementary cementitious materials in cement and concrete industry. A simple sonochemical method was developed to synthesize nanostructures of natural pozzolan. Chemical composition, crystallinity, morphology and reactivity of the natural pozzolan samples were compared before and after the sonochemical process, by ...
