    Sep 15, 2001 · There are many reasons to add polymers to concrete overlay mixes. Polymers improve adhesion to the old surface, flexural strength, tensile strength, and freeze/thaw durability. They also reduce permeability, the intrusion of chlorides, salts, and carbon dioxide. They increase abrasion resistance and can be applied in very thin cross sections.

  • Strength development in concrete - Understanding Cement

    Concrete strength. Many factors influence the rate at which the strength of concrete increases after mixing. Some of these are discussed below. First, though a couple of definitions may be useful: The processes of 'setting' and 'hardening' are often confused: Setting is the stiffening of the concrete after it has been placed. A concrete can be 'set' in that it is no longer fluid, but it may ...

  • Additives for Concrete Waterproofing | AQURON 300

    AQURON 300 additive reduces shrinkage and slabcurl to a minimum, while improving density, anti-dusting, and surface hardness. Cement particles are more effectively "saturated" by the AQURON 300 mix water and this subsequently increases the quantity of hydration products per cement particle, improving achieved strengths, and contributing to a significant drying shrinkage compensation ...

  • High-Strength Concrete

    High-strength concrete is specified where reduced weight is important or where architectural considerations call for small support elements. By carrying loads more efficiently than normal-strength concrete, high-strength concrete also reduces the total amount of material placed and lowers the overall cost of the structure.
