Creating low-shrinkage concrete mixtures decreases the potential for random cracking and warping which have plagued the industry for years. However, these new mixes maximize the coarse aggregate topsize and total coarse aggregate content while minimizing the total paste content (cement and water).
XYPEX ’s performance advantage lies in its unique ability to become an integral part of the concrete mass. By generating a non-soluble crystalline formation deep within the pores and capillary tracts of concrete, Xypex permanently seals the concrete against the penetration of water and other liquids even under extreme hydrostatic pressure.
