Use of Treated Non-Ferrous Metallurgical Slags as Supplementary Cementitious Materials in Cementitious Mixtures

EFFICIENCY FACTOR OF SUPPLEMENTARY CEMENTITIOUS MATERIALS: A STATE OF ART

The use of supplementary cementing materials is gradually increasing due to technical, economical, and environmental benefits. Supplementary cementitious materials (SCM) are most commonly used in producing ready mixed concrete (RMC). A quantitative understanding of the efficiency of SCMs as a mineral admixture in concrete is essential for its effective utilisation. The performance and effective...

Cementitious Properties of Steelmaking Slags

Using Different Methods of Nanofabrication as a New Way to Activate Supplementary Cementitious Materials; a Review

Reducing the consumption of cement with simultaneous utilizing waste materials as cement replacement is preferred for reasons of environmental protection. Blended cements consist of different supplementary cementitious materials (SCMs), such as fly ash, silica fume, Ground Granulated Blast Furnace Slag (GGBFS), natural pozzolans, etc. These materials should be chemically activated to show effec...

Nanomechanical Properties of Cementitious Materials

Nanomechanical Properties of Cementitious Materials Paramita Mondal Although cementitious construction materials are mainly used in a large scale and in huge quantities, fundamental properties such as strength, ductility, creep, shrinkage, and fracture behavior depend, to a great extent, on structural elements and phenomena which are effective at the microand nanoscale. This research involves c...

Development of Sustainable Cementitious Materials

In this paper, two types of sustainable cementitious composites, geopolymer and magnesium phosphate cement, are introduced. The geopolymer is a type of amorphous alumino-silicate products and magnesium cement is MgO based cementitious material. Geopolymer can be synthesized by polycondensation reaction of geopolymeric precursor, and alkali polysilicates. The MgO cement can be obtained by proper...
