Paver Block Hardener is chemical additive used in the production of concrete paver blocks to enhance their strength, durability, and overall quality. The addition of a hardener contributes to the improvement of the physical and mechanical properties of the paver blocks. Paver blocks, also known as interlocking or concrete pavers, are widely used for various outdoor applications such as driveways, walkways, patios, and landscaping. They are designed to improve the compressive strength of the concrete, making the paver blocks more robust. Paver Block Hardener enhances the abrasion resistance of the pavers, making them more resistant to wear and tear.
