In the presence of water, quicklime spontaneously hydrates to form calcium hydroxide. The heat released in this reaction is also used to dry out damp soil rapidly. Moreover, lime neutralises the clayey particles in the soil and binds strongly with them to durably improve the mechanical performance of the treated soils, bringing better resistance to traffic and adverse weather conditions.
These properties allow embankments, platforms and pavement layers for roads, railway tracks, airports, warehouses, etc. to be contructed using local soils and at low cost both financially and environmentally.
Always striving to make the user's job easier, as well as making it possible to treat soil in urban areas, Lhoist has developed Proviacal® RD, a very low dust emission quicklime.
