| 7 | Providing and applying antifungal wash treatment using 3% solution of sodium pentachlorophenate, of reputed brand and manufacturer, on cleaned stone surface at desired locations as per direction of Engineer-in-charge (The rate is inclusive of all materials & labours involved except scaffolding) |
| 8 | Consolidation of loose/ damaged stone masonry with hard stone in super structure above plinth upto five floor level including carefully dismantling of stone, cleaning of mortar and reconsolidating using old reusable stone and new stone both as per site condition and availability of old reusable stone for masonry with Lime Mortar 1:1:1 Lime putty: 1 Surkhi: 1 Coarse sand) (a)Considering 75% reusable old and 25% new stone |
| 9 | Consolidation of loose/ damaged stone masonry with hard stone in super structure above plinth upto five floor level including carefully dismantling of stone, cleaning of mortar and reconsolidating using old reusable stone and new stone both as per site condition and availability of old reusable stone for masonry with Lime Mortar 1:1:1 Lime putty: 1 Surkhi: 1 Coarse sand) (a)Considering 50% reusable old and 50% new stone |
| 10 | Raking out joints of stone masonry surface to the required width and depth, with due care and precaution, by mechanical/ manual means, including preparing and cleaning the surface for re-pointing/ refilling of joints, including disposal of rubbish to the dumping ground within 50 metre lead. |
| 11 | Lime grouting using ratio 1:1 lime and 1 sand/surkhi or as specified by Conservation Consultant /lime grout manufactured under stiff factory conditions (Mape-Antique I or equivalent make) for superior strength to fill all gaps/voids/air pockets visible from bottom of the slab to densify the slab and enhance the contact area within the slab. The lime grout shall be a cement free, fluid hydraulic binder in powder form which should form an injectable slurry made from lime, Eco-pozzolan, natural ultra-fine sand and special additives according to a formulation developed under factory conditions. When mixed with water in mixratio 100:35 (lime powder: water) in a suitable clean container, the lime grout forms a fluid, volumetrically stable injection slurry resistant to salts which is easy to inject with a manual or electronic pump or by gravity casting in structures with cracks, gaps or internal cavities. Once hardened, the properties of slurry made using lime grout, such as mechanical strength, modulus of elasticity and porosity, are very similar to slurry made using lime, lime-pozzolan or hydraulic lime originally used in the construction of old buildings. The lime slurry, shall also have properties which make the product resistant to various chemical-physical aggressive phenomena, such as the presence of soluble salts, freezethaw cycles and alkali-aggregate reactions. Apart from the above, the lime grout must have the following characteristic - Appearance - Powder, Colour - White, Maximum size of aggregate - 100, Bulk density (kg/m3) - 1100, Consistency of mixture - Superfluid, Bleeding - Absent Compressive strength after 28 days (N/mm2)-18 |
