The addition of sodium silicate in the concrete: it gives and when used?

About the "liquid glass" it does not seem to have heard today just lazy, many still do not know the components of a mixture of this and how can I use it in construction.

But a mixture of water and potassium silicate (sometimes sodium silicate) was opened in the Middle Ages, and the 19th century waterglass included in the mass use in construction.

Liquid glass is obtained in two ways:

• The alloy of sodium and silica sand;
• Compound of milled silicon and hot sodium hydroxide;

The result of both methods is obtained translucent viscous mass of white or yellowish in color, in other words, the water glass.

Use of waterglass for the following properties:

• ability to penetration and adhesion;
• creating a waterproof layer on the whole coating material;
• low consumption of water glass to prepare a solution;
• low price of liquid glass.

To that was added into the concrete waterglass: feasibility of material

The basic quality of concrete with the addition of water-glass - the ability for rapid setting and moisture resistance.

Liquid glass is added to the concrete in the following order:

• incorporation appeared in the concrete or the masonry crack;
• for the closing of inter-panel joints;
• for urgent repairs foundation affected by moisture;
• to reinforce concrete ceilings and other structural elements.

Important rules for using liquid glass

• the proportion of waterglass solution in the concrete should not exceed 3%;
• rely solely on liquid glass for waterproofing foundation imprudent: produce additional waterproofing of the foundation other materials.
