Overview of s dodecyl sulfonic acid sodium foaming agent, 70% foaming agent, surfactant anhydrous sodium sulfate
Concrete foaming agent is a specialized chemical admixture used in the production of lightweight cellular or aerated concrete, such as lightweight concrete blocks, CLC (Cellular Lightweight Concrete), or foam concrete. This material introduces stable air bubbles into the concrete mix, significantly reducing its density and increasing insulation properties while maintaining sufficient structural strength. The process involves mixing the foaming agent with water to create a foam, which is then introduced into a cement slurry, creating a lightweight and porous concrete mixture.
Features of s dodecyl sulfonic acid sodium foaming agent, 70% foaming agent, surfactant anhydrous sodium sulfate
Low Density & Lightweight: By introducing countless tiny air pockets, the agent reduces the weight of the final concrete product by up to 75%, making it easier to handle and install.
Insulation Properties: The air-entrained structure improves thermal and acoustic insulation, reducing energy consumption in buildings.
Workability and Flowability: The foam enhances the fluidity of the concrete mixture, improving its ability to flow and fill complex shapes and cavities without segregation.
Environmentally Friendly: Lightweight concrete uses less raw material, particularly cement, which leads to reduced carbon emissions during production.
Durability: Despite its lightness, properly formulated cellular concrete can exhibit good mechanical properties and long-term durability.

The name of the product you're referring to is "sodium dodecyl" or simply "SDS foam agent". It is also commonly known as "70% foam agent" and "anhydrous sodium sulfate surfactant". The formula for this foam agent may look something like this: Na2ODS (sodium dodecyl sulfate) x H2O = (x * (1 - w)) Na2ODS + (w/100) H2O Where: - Na2ODS: sodium dodecyl sulfate - w: foam formation efficiency (usually in percentage) - H2O: water - x: the amount of sodium dodecyl sulfate needed to produce a certain volume of foam - w/100: the foam production efficiency of 100% For example, if you need to create a foam that is 80% foam and want to use 75% sodium dodecyl sulfate as your primary foamant, you would calculate the following: Na2ODS = (80 / 100) * (1 - 0.75) Na2ODS + (0.75 / 100) * H2O Na2ODS = 0.64 Na2ODS + 0.03 H2O Na2ODS = 0.67 Na2ODS + 0.03 H2O So, you would need to add 0.03 g Na2ODS (or equivalent mass of sodium dodecyl sulfate) to 0.03 g of water to get a foam concentration of 0.67. This means that if you need to make a foam that has a density of 0.9 kg/m³, you would need to use about 25% more sodium dodecyl sulfate than it is listed on the label. Note that the exact calculation of foam concentration and foam production efficiency can vary depending on various factors such as temperature, pressure, and surface tension of the foam-forming liquid.

FAQs of s dodecyl sulfonic acid sodium foaming agent, 70% foaming agent, surfactant anhydrous sodium sulfate
Q: How is the foam generated? A: The foaming agent is mixed with water and agitated using a foam generator, producing a stable and consistent foam that is then mixed with the cement slurry.
Q: Does the use of s dodecyl sulfonic acid sodium foaming agent, 70% foaming agent, surfactant anhydrous sodium sulfate affect the strength of concrete? A: While it reduces the density and weight, the right proportion of foam can maintain or even enhance the compressive strength of lightweight concrete, depending on the formulation.
Q: Is it suitable for all types of concrete projects? A: Concrete foaming agents are specifically designed for lightweight concrete applications. They are not typically used in standard concrete projects where high density and strength are required.
Q: Is s dodecyl sulfonic acid sodium foaming agent, 70% foaming agent, surfactant anhydrous sodium sulfate eco-friendly? A: Many modern foaming agents are environmentally safe and do not contain harmful substances. Additionally, using lightweight concrete reduces the overall carbon footprint of a project due to less cement usage.
Q: How does the foam affect the curing process? A: The presence of foam requires careful attention during curing to ensure proper hydration of the cementitious matrix. Adequate moisture retention is crucial to achieve the desired strength and durability.
