Portland Cement High-strength repair mortar, suitable for the preparation of strong cement mortars of increased requirements, for all kinds of applications. The mortars produced using ATLACEM 52.5 HIGH-STRENGTH Portland Cement exhibit excellent compressive and flexural strengths, increased abrasion resistance and high resistance to weather conditions and corrosion caused by the penetration of water into cement mortars. Its use offers a longer lifespan and incomparable resistance to the structures in which it is used. Mixed with building resin (ATLAPLUS LATEX or ATLAPLUS FIBER FLEX), quartz sand and water, it can also be used to create an adhesion bridge for cement mortars.
