This special class of shrinkage- reducing admixture uses a patent-pending technology to limits initial crack width in high-performance, crack-prone (HPCP) concrete mixtures. In lab tests, concrete mixtures were tested in accordance with ASTM C1581 test method created crack widths of at about 175mm (.007 inches). At this width, the crack is nearly invisible to the naked eye. More

When the ASTM Standard Specification for Lightweight Aggregate for Internal Curing of Concrete was published in 2012, the standard change revealed a new understanding about the importance of high-level hydration of concrete. One year later, we look at how ASTM Standards C09 and C09.21 are benefiting the concrete industry. More
Jason Weiss' internal curing research reveals small changes that result in big improvements. For more than a decade, Weiss and his Purdue University students have worked to improve concrete with internal curing. More
