Mortar Rheology with Partial Replacement of Lime with Dredging Residue
摘要
The dredging of harbors is an extremely necessary activity, which is associated with the problem of the disposal of the dredged material, which, even if properly disposed of, affects the environmentEnvironment, not to mention the logistics and disposal costs. Therefore, the present work aims at reducing the extraction of raw materials and reusing the dredging slurry by incorporating the residueResidue into the mortarMortars as a partial substitute for the lime binder. The substitutions were made on a mass base in the mixing ratio of 0, 10, 20, and 30%. The consistency of the mortarMortars was determined using the flow table and checked with the ball test. The squeeze flow test was performed to determine the rheological properties of the mortarMortars. The results were satisfactory, since the binder lime and the dredged slurry have similar granulometry, indicating adequate rheological properties of the material.
