In the framework of a research project financed by Next Generation EU Programme with the Italian Ministry of University and Research, the proposed note explores the possibility of producing lime from eggshells for soil stabilization purposes. The calibration of the production procedure of eggshell lime by calcination is supported by the use of thermogravimetric analysis and X-Ray diffraction and then verified by the fulfillment of International Standard requirements for lime in soil stabilization applications. Physico–chemical and mineralogical characterization of the produced lime is carried out and also preliminary results of a feasibility study of treatment of a clayey soil with the produced eggshell lime are presented. Proctor compaction, initial consumption of lime test and permeability tests in flexible wall permeameters were carried out on untreated soil and on the same soil treated with 4% of eggshell lime. Obtained results are compared with those obtained for the same soil treated with 4% of commercial quicklime.

摘要

In the framework of a research project financed by Next Generation EU Programme with the Italian Ministry of University and Research, the proposed note explores the possibility of producing lime from eggshells for soil stabilization purposes. The calibration of the production procedure of eggshell lime by calcination is supported by the use of thermogravimetric analysis and X-Ray diffraction and then verified by the fulfillment of International Standard requirements for lime in soil stabilization applications. Physico–chemical and mineralogical characterization of the produced lime is carried out and also preliminary results of a feasibility study of treatment of a clayey soil with the produced eggshell lime are presented. Proctor compaction, initial consumption of lime test and permeability tests in flexible wall permeameters were carried out on untreated soil and on the same soil treated with 4% of eggshell lime. Obtained results are compared with those obtained for the same soil treated with 4% of commercial quicklime.
