Limestone knowledge
The catalogue keeps 13 discovery routes but governs 12 material identities: Kadappa and Cuddapah belong to one Kadapa naming lineage. ASTM C568 density class, quarry, lot and suitability all require evidence.
Identity control
Low-, medium- and high-density classes require the applicable ASTM C568 measurements. Petrography should describe texture, pore system, constituents, bedding and alteration relevant to use.
Buying programmes
These programmes organize buying decisions while canonical identity prevents double counting.
Evidence matrix
Use licensed current standards and the project specification. Catalogue text does not publish universal thresholds or infer performance from a region.
Canonical identity
canonical-identityApproved display name, historical/spelling aliases and redirect/lineage rules; aliases must not create duplicate stock identities.
Lithology & density class
petrography-density-classPetrography plus lot-linked density evidence for any ASTM C568 low/medium/high-density classification claim.
Source & lot
origin-and-lotCountry, state/district, quarry/program and bench/block/lot lineage at the precision claimed.
Bedding & orientation
bedding-orientationNatural bed, face, cutting and installation orientation recorded for tests and fabrication.
Visual range
visual-rangeDry/wet range, fossils, veins, pores, stylolites, mineral marks, fill/repair and approval reference.
Dimensions & calibration
dimensionsFinished size, thickness range, calibration, flatness, squareness, edge and surface texture.
Absorption & density
absorption-densityLot-linked ASTM C97 or agreed IS results with specimen condition, laboratory, report and date.
Strength evidence
compression-mor-flexureASTM C170, C99 and C880 results kept distinct, with wet/dry state and orientation where applicable.
Abrasion & slip
abrasion-slipTraffic- and finish-specific results on the exact surface in relevant wet/dry conditions.
Moisture & salts
capillary-saltCapillary rise, drainage, efflorescence, salts/deicing and bedding/joint compatibility assessed for exposure.
Weathering & chemistry
weathering-chemistryFreeze–thaw, wetting/drying, acidic environment, staining and carbonate acid sensitivity reviewed for destination.
Sealer & maintenance
sealer-maintenanceMock-up cleaning, sealing, colour change and maintenance; sealing does not make carbonate stone acid-proof.
Finish control
Approve exact material, lot and finish together.
Application control
Evaluate support, drainage, joints, loading, climate and maintenance with the stone evidence.
RFQ checklist
Every source should answer the same lineage, class, source, range, test, inspection and logistics requirements.
