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

Technology Benefits

Cost effective cementation  Improved mechanical properties  Precisely controlled solidification  Applicable to saturated soil

Technology Application

Dust control Infrastructure construction Soil liquefaction mitigation

Detailed Technology Description

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.

Others

Background

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.
