Significant drying shrinkage is one of the main limitations for the wider utilization of alkali-activated slag (AAS). Few previous works revealed that it is possible to reduce AAS drying shrinkage by the use of shrinkage-reducing ...

Crystalline admixtures and industrial by-products can be used in cement-based materials in order to improve their mechanical properties. The research examined long-term curing and the exposure to environmental actions of ...

In this article, the microstructure of AZ91C magnesium alloy castings produced by investment casting was investigated. Castings were studied in as-cast state and after T4 and T6 heat treatment. The identification of all ...

Six grades of TiAl alloys doped with 7 at.% Nb and variable content of C and/or Mo were studied. The as-received microstructure and phase composition of the alloys was characterized using neutron diffraction experiments ...

New Mg-3Zn-2Ca magnesium alloy was prepared using different processing techniques: gravity casting as well as squeeze casting in liquid and semisolid states. Materials were further thermally treated; thermal treatment of ...

(Ba0.85Ca0.15)(Zr0.1Ti0.9)O3-xCeO2, (BCZTCe) lead-free piezoelectric ceramics were processed conventionally using a two-step sintering technique. The results suggest that two-step sintering is an effective technique to ...

The properties of alkaline activated brick dust mixed with water glass with a silicate modulus (Ms) of 1.0 were studied in fresh mixtures as well as hardened products in connection with the particle size of the dust. The ...

Geopolymers are generally appreciated for their good resistance against high temperatures. This paper compares the influence of thermal treatment with temperatures ranging from 200–1200 °C on the mechanical properties and ...

Geopolymerization of waste products can contribute to the solution of current environ-mental issues related to depletion of natural resources. In this paper, several geopolymer mixes are prepared using waste brick in ...

The properties of alkaline activated brick dust mixed with different amounts of water glass with a silicate modulus (M) of 1.0 were studied in connection with the temperature of curing. The influence of the amount of ...
