How to apply Liquid Sodium silicate on concrete?
How much liquid sodium silicate is added to 100 pounds of cement? Generally add about 25 pounds. When adding water glass, the dosage is set according to 25% of the total amount of cement, if the amount of water glass added is not enough, then it can’t play the role of fast setting, on the contrary, if the amount of water glass added is too much, otherwise it will lead to too thick cement, which will affect the mixing, and the speed of setting is too fast, which will also affect the construction.
The characteristic of liquid sodium silicate is that it can make the cement fast slab curing in 5-10 minutes, and it belongs to the cement curing agent.

How is the viscosity of liquid sodium silicate measured?
When using liquid sodium silicate as a binding agent for refractory materials, its workability (meaning molding performance) mainly depends on the viscosity, which varies with the density and modulus of water glass, and the relationship is shown in the figure below. In the case of the same density, the higher the modulus, the greater the viscosity. Modulus of large liquid sodium silicate, with the increase in density, the more dramatic viscosity increase. For small modulus liquid sodium silicate, the viscosity changes slowly with density, which is related to the content of colloidal silica in sodium silicate solution. The higher the modulus, the more colloidal silica content, and the stronger the colloidal nature of the sodium silicate solution. On the contrary, the lower the modulus, the lower the colloidal silica content in the water glass, the stronger the non-colloidal nature of the whole system, so the viscosity tends to moderate with the density change.
M=1.023 x SiO2/Na2O
