Customising Microstructural and Mineralogical Characteristics of Hydrated Lime Using Biopolymers

نویسندگان

چکیده

The study of lime-based systems is vital to the design new sustainable building materials. Air lime (calcium hydroxide, Ca (OH) 2 ) a binder that has attracted considerable attention for its ability capture CO from atmosphere, low-cost and low-energy production process. Furthermore, an important phase hydrated Portland cements, mortars have shown high elasticity self-healing. performance materials can be enhanced by addition organic compounds modify mineralogy microstructure . In this study, effects four biopolymers including starch, inulin, pectin, calcium lignosulfonate, on been investigated. Hydrated was produced slaking quicklime in water. Two sets batches were each polymer: (i) polymer previously dissolved water subsequently mixed with lime, (ii) added as dry powder already at end Characterisation performed using scanning electron microscopy, X-ray diffraction laser diffraction. Results indicate affect nucleation growth crystals. This influences crystal aggregation colloidal suspension, which will implications use cement applications mortars.

Hydrated lime for metals immobilization and explosives transformation: Treatability study.

Fragmentation grenades contain Composition B (RDX and TNT) within a steel shell casing. There is the potential for off-site migration of high explosives and metals from hand grenade training ranges by transport in surface water and subsurface transport in leachate. This treatability study used bench-scale columns and mesocosm-scale laboratory lysimeters to investigate the potential of hydrated ...

Genetic Variation of Lime (Citrus sp.) Accessions Using Flow Cytometry Technique, Morphological Characteristics and Molecular Markers

Because of sexual propagation of Mexican lime in southern regions of Iran, there are many lime accessions (lime biotypes) in Mexican lime gardens in which appear some variation in fruit and tree shape. However, most of these accessions are susceptible to witches broom disease of lime (WBDL). Persian lime (C. latifolia Tanaka) is a triploid WBDL-tolerant species. Considerable number of un-descri...
