In this direction, the<br> present paper presents the results of an experimental campaign aimed at analyzing the effectiveness<br> of low-pressure grouting of sand with nanosilicatesto mitigate the effects of liquefaction.<br> Sandy specimens, reconstituted at two initial relative densities have been treated with<br> grout prepared with silica content ranging from 1.2% to 5.0% by weight, cured for different<br> periods and have then been subjected to different physical and mechanical tests. The results<br> reveal a lower tendency of the treated material to accumulate excess pore pressuresduring<br> undrained cyclic loading, proving in this way that the technique can be successfully adopted<br> to mitigate the effects of liquefaction of loose sandy deposits.</p></description> </descriptions> <fundingReferences> <fundingReference> <funderName>European Commission</funderName> <funderIdentifier funderIdentifierType="Crossref Funder ID">10.13039/100010661</funderIdentifier> <awardNumber awardURI="info:eu-repo/grantAgreement/EC/H2020/700748/">700748</awardNumber> <awardTitle>Assessment and mitigation of liquefaction potential across Europe: a holistic approach to protect structures / infrastructures for improved resilience to earthquake-induced liquefaction disasters</awardTitle> </fundingReference> </fundingReferences> </resource>
