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. Higher early strengths allow for faster form removal, saving time in the plant and at the job site, while reduced permeability improves resistance to sulfuric acid and other harmful chemicals.
