Chryso®Dry-Block G3 (formerly DRY-BLOCK® G3)

Chryso®Dry-Block G3 provides water repellency and improves cement dispersion. This dispersion action may allow for cement and pigment reductions, though testing is recommended to determine the reduction potential. It may also permit increased water in the concrete mix, promoting greater cement hydration in the CMU. Additionally, it enhances the plasticity of the mix, eliminating the need for a second admixture for machinability.

Chryso®Dry-Block System consists of two separate admixtures: Chryso®Dry-Block G3, which is mixed throughout the concrete during the manufacture of the concrete masonry unit (CMU), and Chryso®Dry-Block Mortar, which is added to the mortar. Through its novel chemistry, it provides excellent water repellency while improving color vibrancy and controlling both primary and secondary efflorescence.
