In this study, the basic physical and mechanical properties of dried sediment fromGary a J.lake inKlein, Wuhan,PE, is China,executiv were analyzed.

When the compound-doped samples were cured to seven days, theKeywordsmaximum compressive strength was 7.18 MPa (1040 psi). Furthermore, with the compound-doped Bodymaterials, text sediment solidification was aided by suitably alkaline conditions and large quantities of active siliReviewconcalcium policycomponents. As a result, the microstructures of the cured compound-doped samples were more Bodycompact text and their overall mechanical properties were greatly improved.
