  1. Moscow State University of Civil Engineering Scientific and Educational Center “Nanotechnology” Synthesis and investigation of properties of nanoscale foam stabilizer for foam concretes with synthesized foamers Spokesperson: Anna Grishina

  2. Model of the “iron III hydroxide soland sodium hydrosilicates” system

  3. Average size of the particles in “iron III hydroxide sol and sodium hydrosilicates” system Reference system:=0 =0.5 =1 =1.5

  4. Viscosity of the “iron III hydroxide sol and sodium hydrosilicates” system = 0 = 0.5 = 1.5  = 1  - С = 0.17%; □ - С = 0.33%;  - С = 0.50%

  5. Viscosity of system formed by iron hydroxide sol (0.66%), sodium hydrosilicates and “PB Lux” foamer ♦ – = 1.2; ◊ –  = 1.4; ■ –  = 1.5; ▲ – = 1.7%; ○–  = 1.8; ∆ – = 1.9; □ –  = 2.0

  6. Parameters of foams produced with «PB Lux» foamer рН value of the nanoscale admixture Note: рН of solutions are specified for 28оС

  7. Compressive strength of the nanoscale-modified foam concretes Relative strength of the developed nanoscale-modified foam concrete as a dependence from foamer content and a parameter Strength of the developed nanoscale-modified foam concrete as a dependence from foamer content and a parameter

  8. Practical application of the “iron hydroxide soland sodium hydrosilicates” system
