READY-MIX CONCRETE
durability admixtures
We offer only time-tested proven technologies that offer a fast, permanent, disrupted capillary system in concrete. Our goal ~ to defeat the "mass transport" system in portland cement-based concrete. Period.
Time and tens of thousands of cubic yards of concrete has shown that Secondary Cement Hydration can, and is the best vehicle to get us there. Secondary Cement?? Hydration?? A fancy way of saying "extra" or "amplified" cement hydration product....or more appropriately, more calcium-silicate-hydrate (c-s-h).
Normal cement mechanics (hydration) gives us c-s-h and calcium hydroxide. c-s-h is good; all the best parts or "glue" that holds a properly graded aggregate mix together. Calcium hydroxide, more of the weaker stuff; more permeable, less strength. We use siliceous/pozzalonic materials to react with water and calcium hydroxide to make more c-s-h. Natural, automatic enhancement. Stable, consistent products sold through the commercial ready-mix producers.
*Note - It's important to remember, this is the same basic way quality fly ash and slag work. Those are "by-products" we started using to "hide" both of them. It worked. There is very little quality fly ash and slag left to use on the West Coast. An even bigger reason to entertain Durability Admixtures!
Part of the Durability Enhancing of OPC Concrete with CWPA 800 is:
-
reduced shrinkage; high-performing SRA,
-
Corrosion Inhibitor,
-
Viscosity Modifier; VMA,
-
Water Proofing
*This admixture was designed to stop moisture/vapor coming through concrete subjected to pressure/humidity/temperature gradients in buildings....stopping water head pressure against one side of concrete is merely an ancillary benefit.
**For a number of discerning owners and developers, we've offered long-term Warranted structures; i.e. we will fix any water leaks for an agreed upon period of time beyond significant completion. This is called the DRY conCRETE WATERTIGHT WARRANTY. And we've got lot's of Case Studies of doing exactly that; exposed podium decks, mat/raft slabs, slab-on-ground, pool decks, waster water treatment facilities and lot's of structural walls. Poured-in-place or shotcrete. You won't be the first. But you can be the next! Reach out today to discuss duration and details of your next project....
