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