Aside from water the materials which are used by mankind in highest
quantities arecementitious materials and concrete. This book shows
how the quality of the technical product depends on mineral phases
and their reactions during the hydration and strengthening process.
Additives and admixtures infl uence the course of hydration and the
properties. Options of reducing the CO2-production in cementitious
materials are presented and numerous examples of unhydrous and
hydrous phases and their formation conditions are discussed. This
editorial work consists of four parts including cement composition
and hydration, Special cement and binder mineral phases,
Cementitious and binder materials, and Measurement and properties.
Every part contains different contributions and covers a broad
range within the area. Contents Part I: Cement composition and
hydration Diffraction and crystallography applied to anhydrous
cements Diffraction and crystallography applied to hydrating
cements Synthesis of highly reactive pure cement phases
Thermodynamic modelling of cement hydration: Portland cements -
blended cements - calcium sulfoaluminate cements Part II: Special
cement and binder mineral phases Role of hydrotalcite-type layered
double hydroxides in delayed pozzolanic reactions and their bearing
on mortar dating Setting control of CAC by substituted acetic acids
and crystal structures of their calcium salts Crystallography and
crystal chemistry of AFm phases related to cement chemistry Part
III: Cementitious and binder materials Chemistry, design and
application of hybrid alkali activated binders Binding materials
based on calcium sulphates Magnesia building material (Sorel
cement) - from basics to application New CO2-reduced cementitious
systems Composition and properties of ternary binders Part IV:
Measurement and properties Characterization of microstructural
properties of Portland cements by analytical scanning electron
microscopy Correlating XRD data with technological properties No
cement production without refractories
Industrial residues are obtained from all treatments of raw
materials in industry during the process of mining, raw materials
treatment and final usage. During these processes of enrichment,
optimization and utilization of raw materials only part of the
original material can be used for the dedicated application and
some left-over parts remain. This contribution focuses on residues
like mining overburdens, ore residues and ore processing residues
like slags, but also on incineration ashes and water purification
muds. Natural materials like pozzolanes, due to their potential of
CO2-reduction, are also included. Based on this knowledge secondary
reusable materials due to their chemical, physical and
mineralogical properties can be identified. Also different
characterization methods for analysing the potential for further
application of these residues are included.
