Highly Ductile And Durable Double-Network Based Cementation – “D3 Cement” By Using Self-Healing Organic-Inorganic Double Network

Tech ID: 29284 / UC Case 2018-192-0


UCLA researchers in the Department of Materials Science and Engineering have developed a self-healing cementing material with high ductility and durability.


Soil stabilization has gained increasing attention as urbanization occurs at sites with suboptimal soil conditions. Environmental protection from dust generated by weak soil has also increased the demand for soil stabilization. Current stabilization methods by cementation have a limited lifetime or require heavy machinery. Emerging bio-cements also suffer from brittleness and low durability. Thus, there is a need for cement materials with improved ductility and toughness.


UCLA researchers have developed a highly ductile and durable cementation material known as “D3 Cement”. The self-healing organic-inorganic double network provides cost effective cementation with improved mechanical properties and precise solidification. This technique is also applicable to saturated soil. Soil stabilization by D3 cement increases land use capacity for sites with less optimal soil conditions, prevents geological hazards caused by overdevelopment, and mitigates damage from natural disasters. Moreover, knowledge from the cementation technique has broader applications, including sand aggregate building materials.
