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 ...

Effect of nanoparticles on foaming agent and the foamed concrete
Construction and Building Materials, 2019Abstract 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, 2022In 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 ...

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 ...

Effect of activated foaming agent on the foam concrete properties
Construction and Building Materials, 2016Abstract 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.

Synthesis of Compound Foaming Agent of Lightweight Foamed Concrete
Advanced Materials Research, 2013The foaming agent used in lightweight gypsum-based foam concrete was discussed. The effect of the single-doped foaming agent, codoped foaming agent and ternary foaming agent on the settling height, bleeding volume and defoaming time of fresh foam were investigated.

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

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
