Understanding Sodium Silicate Concrete Hardeners

What is Sodium Silicate Concrete Hardener

A sodium silicate concrete hardener is a liquid solution you apply to concrete surfaces. It works to improve the strength and durability of your concrete. Typical sodium silicate concrete hardeners, such as Civilox-Si25, are composed of sodium silicate, also known as water glass. These are one-component densifiers designed to penetrate concrete and react chemically to seal and harden the surface. You use this product to create a more resilient concrete floor. It helps you achieve a better finish on your floor.

Chemical Reaction and Concrete Benefits

When you apply a sodium silicate hardener, it penetrates the concrete surface. The silicates react with calcium hydroxide, a byproduct of cement hydration, present in the concrete. This reaction forms a calcium silicate hydrate (C-S-H) gel. This gel fills the pores within the concrete, making the surface denser and harder. This process significantly increases the concrete’s strength and reduces its porosity. You will notice improved performance and greater durability for your concrete floor. This chemical change also helps to prevent dusting, a common problem with untreated concrete. It gives your floor a much stronger finish.

Why Use a Sodium Silicate Hardener

You should use a sodium silicate hardener to address common issues with concrete floors. Untreated concrete often suffers from dusting, abrasion, and general wear. A hardener provides a cost-effective and long-lasting solution. It enhances the surface, making your concrete floor more resistant to traffic and spills. This treatment reduces maintenance needs for your floor. For those considering floor polishing, a hardened concrete surface is ideal.
