Concrete densifying admixture

CDA ii

ConBlock CDA contains pure silicon dioxide dispersed in a proprietary liquid that densifies and waterproofs concrete. Against reference mix designs, users can anticipate a faster set with less bleed water and earlier strength gains, owing to accelerated cement hydration, plus higher 28-day compressive strength. The reduction in surface bleeding allows for faster finishing and a more durable slab or structure.
