The research team is developing a shrinkage reducing admixture for application in portland cement-based materials such as concrete. This technology focuses on reducing the surface tension of the pore solution by disrupting the hydrogen bonding of water molecules in the liquid phase at the vapor-liquid interface. The basis of this technology lies in the team?s ability to predict new structures using an intelligent computer aided molecular design methodology that utilizes quantitative structure property relationships (QSPR) and inverse design logic. This is one of the first demonstrations of the use of computer aided molecular design using QSPR to discover new admixtures for concrete.Concrete is one of the major building blocks of roads and structures across the globe, and each year billions of dollars are spent replacing concrete damaged due to cracking-related issues. The admixture developed by this research team would serve to help reduce shrinkage of concrete, which is one of the main causes of concrete cracking, damage and failure. Concrete that is less prone to damage would result in less cost for repair and overall, stronger, more durable structures and roadways.

研究团队正在开发减少混合物的收缩，以在波特兰水泥基材料（例如混凝土）中应用。该技术着重于通过在蒸气液界面处液相中的水分子的氢键来减少孔隙溶液的表面张力。这项技术的基础在于团队使用智能计算机辅助分子设计方法来预测新结构的能力，该方法利用了定量结构属性关系（QSPR）和逆设计逻辑。这是使用QSPR使用计算机辅助分子设计的首次演示之一，以发现混凝土的新混合物。Concrete是全球道路和结构的主要构件之一，每年花费数十亿美元用于替换因裂缝相关问题而造成的混凝土。该研究团队开发的混合物将有助于减少混凝土的收缩，这是混凝土破裂，损坏和失败的主要原因之一。不太容易受损的混凝土将减少维修成本，整体上，更坚固，更耐用的结构和道路。
