A database was compiled which cement manufacturers can use to influence and further optimise the formation of the melt phase by selecting suitable alternative fuels and their proportion.
The research activities continued the project “Low alkali cements with fly ash” (IGF 17249N) with two main targets. Firstly the effects of different characteristics of cements with fly ash on the release of aluminium into the pore solution were investigated. Secondly it was looked into how much each of the examined mechanisms (reduction of the alkali ion concentration, reduction of portlandite availability, release of aluminium into the pore solution, change of the cement stone microstructure) contributes to the prevention of a deleterious ASR.
Aim of the project was to improve the early strength performance of blastfurnace cements by a systematic adjustment of the clinker phase composition and/or addition of mineralisers in the clinker production process.
A laboratory method and a method on the internal particle size distribution that can be used on-site in a cement plant were developed in this research project.
It was determined how the rheological properties and the consistency of fresh concrete can be improved by the adjustment of the type and proportion of fly ash or calcined clay in the cement to the clinker as well as the type and dosage of the superplasticizer.
The research project initially involved a sequence of steps to formulate robust, automated preparation methods and evaluation files and determine their reproducibility.
The aim of the research project was to determine interactions between superplasticizers and cements with calcined clay.
The main scope of this research project was to supply evidence that selected inorganic substances are suitable for the use as minor constituents.
