11/04/2018 · Increase Concrete Durability by Keeping Water Out. by Sarah McGuire ... Nanoadditives change the concrete on a molecular level once it has hardened, resulting in a spiky surface noticeable at a microscopic level. This rough surface causes the water to bead and roll off on contact. Think of a leaf with beads of water sitting on its hairy surface.

AQURON 300 additive reduces shrinkage and slabcurl to a minimum, while improving density, antidusting, 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, optimising achieved strengths, and contributing to a significant drying shrinkage compensation ...

Portland cement concrete usually does not have good resistance to acids. Some weak acids, however, can be tolerated, particularly if the exposure is occasional ().There are essentially three ways to improve concrete's resistance to acids, (1) choosing the right concrete composition to make it as impermeable as possible, (2) isolating it from the environment by using a suitable coating or (3 ...
