Cement foaming agent, refers to can reduce the liquid surface tension, produce a large number of uniform and stable foam, used to produce foam concrete admixture.Foaming agent is a kind of substance that can produce a large number of foams when its aqueous solution is introduced into the air under the mechanical force. This kind of substance is surfactant or surfactant, and only a small part of it can be used in foamed concrete, which is determined by the characteristics and technical requirements of foamed concrete.

Different volumes of liquid foam and constant water-cement quantitative relation (0.55) were wont to prepare a group of froth concretes via pre-formed foaming. The liquid foams consisting of supermolecule foaming additive, water and air, created by victimization foam generator, were mixed with hydraulic cement – water suspensions. The impact of the foaming agent concentration and its microwave and inaudible treatment was examined in respect to the foam stability, bulk density, microstructure and ensuing compressive strength. Micrographs from scanning microscope (SEM) were wont to verify a median pore size. The crystalline part composition of the samples was assessed by XRD analysis and coincidental TG-DTA was wont to study their thermal stability. attenuate pore size that accounts for compressive strength improvement was resolute within the samples ready with lower concentration of microwave and inaudible treated foaming agent. Lower concentration of foaming agent itself conjointly had positive impact on the soundness of the froth. However, its influence wasn't thus distinguished.


Foamed concrete will be created either by the pre-foaming technique or the mixed-foaming technique. within the pre-foaming technique, an appropriate foaming agent is mixed with water, and therefore the foam is combined with paste or mortar. Meanwhile, within the mixed-foaming technique, the foaming agent is intercalary to the suspension, and therefore the mixture is whisked into a stable mass that has the specified density. The producing of stable mixture of foamed concrete depends on several factors, like the choice of the foaming agent, the tacticwont to prepare the froth to get a consistent air-void distribution, choice of materials, methods for mixture style, and therefore the production of foamed concrete. varied foaming agents are wont to manufacture foamed concrete, together with detergents, resin soap, glue resins, saponin, and hydrolyzed proteins, like albuminoid and similar materials.
