Three-phase-foams for foam concrete application
Materials Characterization, 2015Abstract Minerally bound foams are used throughout in the building industry for their combination of load bearing capacity and thermal insulation. Nowadays this can be achieved by lightweight concretes, especially with aerated and foam concretes. Blocks made of aerated concrete as well as prefabricated components are well-known.

Study on Foaming Agent Foam Ability and Stability for Foam Concrete
Applied Mechanics and Materials, 2013Foam 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 ...

Non-autoclaved Foam Concrete with Improved Foam Characteristics
2021In the production technology of non-autoclaved cellular concrete, there are a number of technological changes, the possibility of intensifying which is possible by inserting chemical and mineral additives-stabilizers of the foam matrix. These additives can simultaneously act as accelerators of hardening and setting, as well as stabilize the foam matrix

Influence of foaming agent on cement and foam concrete
Construction and Building Materials, 2021Abstract Foaming agent is an indispensable component in preparation of foam concrete by using prefabricated foams. In this study, four types of foaming agents were used to prepare foam concrete. Effect of foaming agent on properties of fresh and hardened foam concrete, interaction between foaming agent and cement, and the gas–liquid interface in foam

Sorption characteristics of foam concrete
Cement and Concrete Research, 2007Knowledge of sorption characteristics like absorption and sorptivity of building materials are of importance as they affect the durability and other properties. In the case of lightweight concrete like aerated and foam concrete, the moisture movement behaviour becomes more complex as such concretes contain much larger volume of air voids. This paper is

Durability of foamed concrete – freeze-thaw resistance of foamed concrete
Inżynieria i BudownictwoAlthough foamed concrete was practically created about 100 years ago, there are no current standards for foamed concrete and test methods for determining its properties. Hence, while the assessment of mechanical properties can be found in the literature, the assessment of the durability of foamed concrete is rare and is most often carried out due to a ...
