  "description": "<p>The severe damages on buildings and infrastructures induced by earthquake<br>\nliquefaction has highlighted the importance of implementing reliable techniques to reduce the<br>\nsusceptibility of loose sandy deposits beneath new or existing buildings. In this direction, the<br>\npresent paper presents the results of an experimental campaign aimed at analyzing the effectiveness<br>\nof low-pressure grouting of sand with nanosilicatesto mitigate the effects of liquefaction.<br>\nSandy specimens, reconstituted at two initial relative densities have been treated with<br>\ngrout prepared with silica content ranging from 1.2% to 5.0% by weight, cured for different<br>\nperiods and have then been subjected to different physical and mechanical tests. The results<br>\nreveal a lower tendency of the treated material to accumulate excess pore pressuresduring<br>\nundrained cyclic loading, proving in this way that the technique can be successfully adopted<br>\nto mitigate the effects of liquefaction of loose sandy deposits.</p>",
