Durability Properties of High Performance Foamed Concrete

Effect of viscosity modifier admixture on Portland cement paste hydration and microstructure

“…This phenomenon might be correlated with the large amount of entrapped air voids found on samples with HPMC. Accelerated carbonation was previously reported for foamed concrete, as the total surface area exposed to the gas is larger [45]. The total amount of calcium carbonate in the cement used during this study was 1.22%.…”

Geopolymer eco-cellular concrete (GECC) based on fluid catalytic cracking catalyst residue (FCC) with addition of recycled aluminium foil powder

“…The result is a material characterized by its internal air-void structure (gas bubbles trapped in fresh state), which has been stabilized with an autoclaving-accelerated hardening treatment [2]. Owing to the air-void structure, this material has low density (values of 300 to 1400 kg/m 3 ) [3], low thermal conductivity (5-30% of those measured on normal weight concrete) [4,5], great acoustic insulation, freeze-thaw resistance (to a defined saturation level) [6,7] and high fire resistance (above 600ºC keeping their properties unchanged) [8]. Due to these properties, TCC is a more durable material than traditional concrete [9][10][11].…”

Experimental investigation on foamed concrete produced using a planetary ball mill

“…AAC is obtained by chemical aeration with special gas mixture. As the most popular material is autoclaved gas silicate concrete and they are described by high porosity and water absorption (Namsone, Sahmenko, & Namsone, 2018;Namsone, Sahmenko, & Korjakins, 2017c).…”

“…The lightweight, water absorption and insulation are advantages properties of this material (C. Sun, Zhu, Guo, Zhang, & G. Sun, 2018). So it is one of the more widly used building materials not only for prefabricated but also monolithic constructive elements (Namsone et al, 2017c;Namsone et al, 2018).…”

“…But comparing to aerated autoclaved concrete, the use of FC is limited according to lower compressive strenght values and bad shrinkage behaviour. There can be used different pore-forming additives and fibres with high strength to improve necessary mechanical and physical properties of material (Namsone et al, 2017c;Namsone et al, 2018).…”
