Silica and alumina nanoparticles cut shrinkage in polyurethane/epoxy grout
Source: Wiley, "Dual Nanoparticles Synergistically Reinforce Polyurethane/Epoxy Grouting Material with High Mechanical Properties and Low Volume Shrinkage", published 23 October 2026.
What the source says
Polyurethane/epoxy grouting reinforced with silica and alumina nanoparticles achieved 0.39% volume shrinkage. Grouting model tests produced a consolidated body with compressive strength of 68 MPa.
Allbase view
Lab results only, so not yet a basis for specification, but if nanoparticle-reinforced polyurethane/epoxy grouts reach the market they could suit crack injection and ground consolidation where shrinkage gaps are a risk. Specifiers should expect to ask for independent field data, cure behaviour and pricing before weighing them against established systems.
