BASF introduces MasterLife CRA 007 breakthrough crack-reducing admixture technology for concrete
New solution makes crack widths almost invisible to the naked eye
The Admixture Systems business of BASF’s Construction Chemicals division announced today the launch of a unique crack-reducing admixture technology in the U.S. and Canada. MasterLife CRA 007 admixture enhances the aesthetics and long-term durability of concrete by reducing the likelihood that cracking will occur and, if it does, minimizes the crack width. This patent-pending technology is a special class of shrinkage reducing admixture that produces a maximum initial crack width of 175 microns (.007 inches) in high-performance, crack-prone (HPCP) concrete mixtures tested in accordance with ASTM C1581 test method. This minimized crack width is nearly invisible to the naked eye. Crack widths this small do not transport water and have the potential to self-heal over time, thus increasing concrete durability by minimizing the ingress of chlorides, sulfates, and other potentially harmful materials.
“Cracking is a major issue for the concrete industry, as it detracts from
the aesthetics of concrete, can be a safety hazard, and may
compromise durability or structural integrity”, said Juan Alfonso
Garcia, Vice President, BASF – Admixture Systems. “MasterLife CRA
007 admixture is a breakthrough technology that minimizes cracking
and improves concrete quality.”
MasterLife CRA 007 admixture will meet ASTM C494, Standard Specification for Chemical Admixtures for Concrete, Type S, Specific Performance Admixtures.
“Many of today’s concrete specifications are embracing performance-based solutions,” said Dr. Charles Nmai, Manager, Engineering Services, BASF – Admixture Systems. “BASF is committed to developing products like MasterLife CRA 007 admixture that improve concrete performance through enhanced durability, extending the service life of structures and minimizing cost and environmental impact.”
MasterLife CRA 007 admixture is part of the Master Builders Solutions portfolio of products for the construction industry. This portfolio includes: concrete admixtures, cement additives, chemical solutions for mining and tunneling, sealants, waterproofing, concrete protection and repair products, grouts, and performance flooring products.
