ABSTRACT:
The pozzolanic properteis of a pozzolanic material, such as a fly ash, are improved by mixing the pozzolanic material with a calcium oxide or calcium hydroxide containing material and water in such a way that at the time of associating or bringing together the abovementioned components the mixture has or immediately attains a temperature of more than 50.degree. C., preferably at least 80.degree. C., most preferably 85.degree. to 100.degree. C.
A mixture of pozzolanic material and calciumoxyde and/or calcium hydroxide may be preheated, water subsequently is added to said mixture.
Hot water may be used and is preferably added as one mass at one moment.
The pozzolanic material obtained from the process of the invention is suitable as cement substitute, as material for manufacturing building articles and a binder for occluding one or more fillers to be introduced into a chemical process or one or more fillers presenting noxious properties.
