How many types of foaming agents are used to prepare foam concrete?

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 concrete were studied.

What is the interaction between foaming agent and cement?

The interaction between foaming agent and cement plays a greater role in the formation process of foam concrete. And the property of gas–liquid interface of foam concrete is the most important factor for the performance of in foam concrete.

Can cationic or non-ionic foaming agent be used in insulating foam concrete?

So, cationic or non-ionic foaming agent should not be used to prepare low density insulating foam concrete. At present, composite foaming agent is widely used in foam concrete production. The interaction between cement and foaming agent is more complex and more work needs to be done.

Which surfactant helps form open-cell foam concrete?

Anionic and nonionic surfactant help form open-cell foam concrete. Unstable foamed concrete due to excessive change of surface tension of slurry. 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.

How foaming agent affect pore wall?

Hydrophilicity of cement absorbed foaming agent influence product in the pore wall. Anionic and nonionic surfactant help form open-cell foam concrete. Unstable foamed concrete due to excessive change of surface tension of slurry. Foaming agent is an indispensable component in preparation of foam concrete by using prefabricated foams.

Is composite foaming agent used in foam concrete production?

At present, composite foaming agent is widely used in foam concrete production. The interaction between cement and foaming agent is more complex and more work needs to be done. Li Hou: Investigation, Writing – original draft.
