Which is another name for sodium silicate?

water glass, also called sodium silicate or soluble glass, a compound containing sodium oxide (Na2O) and silica (silicon dioxide, SiO2) that forms a glassy solid with the very useful property of being soluble in water. Water glass is sold as solid lumps or powders or as a clear, syrupy liquid.

What can I use instead of sodium silicate?

Rice husk ash (RHA), a by-product from the rice industry, was used as principal source of amorphous silica for the production of sodium silicate solution (MR ∼ 3) used for the replacement of standard commercial sodium silicate in the mix-design of metakaolin based geopolymer composites.

How do you make sodium silicate glue?

Prepare Sodium Silicate

  1. Wear proper safety gear, which includes gloves.
  2. Heat 4 to 8 grams of sodium hydroxide in 10 milliliters of water.
  3. Once the sodium hydroxide is dissolved, slowly add 6 grams of crushed silica gel beads. Heat the solution between additions.
  4. You now have sodium silicate or water glass.

What is sodium silicate used for?

Sodium silicate has been used to preserve eggs, fireproof fabrics, and waterproof walls. Most commonly, it is used as a cement for abrasive wheels, bonding paper, corrugated boxes and cartons, wood, glass, porcelain, leather, and textiles. A water glass solution is viscous and has little tack.

How is sodium silicate used with cement?

Sodium silicate reacts with the calcium hydroxide in hydrated cement paste to form calcium-silicate-hydrate gel that fills cracks. It is observed that the microcapsule addition inhibits compressive strength development in cement and this is observed through a plateau in strength between 28 and 56 days.

What does sodium silicate do to concrete?

It reduces the size of the pores, therefore increasing density and strength. There are a few benefits to use a sodium silicate sealer: Silicate sealers will reduce dusting and deterioration caused by surface abrasion by increasing the surface strength and density of the concrete.

Who uses sodium silicate?

The main applications of sodium silicates are in detergents, paper, water treatment, and construction materials.

How do you mix sodium silicate with water?

Bring purified water to a low simmer (approximately 175 degrees) on an electric stove. Stir sodium silicate powder into hot water with a long-handled metal spoon. Continue stirring until the powder is completely dissolved. Remove solution from heat and allow it to cool to room temperature.

How do you apply sodium silicate to concrete?

The proper way to apply sodium silicate:

  1. It should be applied in light, even coats; it should look saturated, but not oversaturated.
  2. Don’t apply too many coats. After the first coat, it should be waited for 24 h to pass, and then apply another one.
  3. Wait for the sealer to fully cure before applying paint.

What is silicate glue?

Sodium silicate adhesives are used for bonding a variety of porous surfaces and materials such as paper, mineral wool (used in insulation), perlite, mica and wood. As silicates lose water, their viscosities increase and strong bonds are formed (Table 2).
