Study on Foaming Agent Foam Ability and Stability for Foam Concrete

Applied Mechanics and Materials, 2013
Foam ability and stability of foaming agent are key factors for foam concrete properties. Through researching LAS, SDS and magnesite foaming agent commercially available, the results show that adding HPMC after can reduce LAS, SDS and magnesite foam bleeding quantity and subsidence distance and has little impact on foam expansion, magnesite foam ...

Effect of nanoparticles on foaming agent and the foamed concrete

Construction and Building Materials, 2019
Abstract Nanoparticles are expected to improve properties of foaming agents and that prefabricated foams, further the performances of foamed concrete. In this study, foaming agents were prepared by introducing a certain content of nano-SiO2 (NS) and graphene (G), respectively.

Effect of foam volume on penetration parameters of foamed concrete

Magazine of Concrete Research, 2022
In this research, the effect of porosity owing to foam on the penetration parameters of foamed concrete, including absorption and chloride ingress, is evaluated. The penetration parameters of foamed concrete are determined using a water/cement (w/c) ratio of 0.5 and foam contents of 20, 35 and 50%, and then compared with the base mix without foam and ...

Effect of activated foaming agent on the foam concrete properties

Construction and Building Materials, 2016
Abstract Different volumes of liquid foam and constant water-cement ratio (0.55) were used to prepare a set of foam concretes via pre-formed foaming. The liquid foams consisting of protein foaming additive, water and air, produced by using foam generator, were mixed with Portland cement – water suspensions.
