Comparative study on the performance of protein and synthetic-based foaming agents used in foamed concrete

open access: yesCase Studies in Construction Materials, 2021
Foamed concrete is a composite material with a density that is significantly lower than standard concrete. The property of being lightweight is due to tiny air voids produced by the addition of foaming agents in cement paste. The purpose of this research

Fibre-Reinforced Foamed Concretes: A Review [PDF]

open access: yesMaterials, 2020
Foamed concrete (FC) is a high-quality building material with densities from 300 to 1850 kg/m3, which can have potential use in civil engineering, both as insulation from heat and sound, and for load-bearing structures. However, due to the nature of the cement material and its high porosity, FC is very weak in withstanding tensile loads; therefore, it ...

Experimental Study on the Application of Recycled Concrete Waste Powder in Alkali-Activated Foamed Concrete. [PDF]

open access: yesMaterials (Basel), 2023
The alkali-activated cementitious material was prepared by partially replacing slag with recycled concrete powder (RCP). The influence of RCP substitution rates (10%, 20%, 30%, 40%, and 50% mass fraction) on the performance of alkali-activated slag-RCP ...

Efficacy and mechanism of graphene oxide modified silane emulsions on waterproof performance of foamed concrete

open access: yesCase Studies in Construction Materials, 2022
As a lightweight construction material, foamed concrete has garnered considerable attention due to a variety of advantages. However, the high-water absorption increases the burden on the structure and accelerates freeze-thaw damage, and thus reduce the ...
