• Quarrying of Stones: Methods of extraction (Blasting, Wedging) and essential tools/materials.

• Criteria for Selection of Stones: How to choose the right stone based on strength, durability, and appearance.

• Deterioration and Preservation: Why stones decay and how to protect them during construction.

• Artificial Stones & Stone Veneering: Classification based on texture and man-made stone alternatives.

• Laboratory Tests on Stones: Physical tests like Crushing strength, Water absorption, and Hardness test.

Part 2: Bricks and Clay Products (ईंटें और मिट्टी के उत्पाद)

• Brick Earth and Manufacturing: Composition of good brick earth and the step-by-step preparation process.

• Chemical Changes and Dimensions: Changes during the burning process and standard dimensions (19cm x 9cm x 9cm).
• Special Purpose Bricks: Heavy-duty bricks, storage methods, and weight of brickwork.
• Special Shapes and Lightweight Bricks: Perforated, hollow, and light-clay bricks for modern construction.
• Alternatives to Bricks: Fly ash bricks, sand-lime bricks, and their various types.

• Testing of Bricks: Compressive strength, Efflorescence, and Soundness tests.

Part 3: Concrete Blocks (कंक्रीट ब्लॉक)

• Use of Concrete Blocks: Application in masonry and comparison with traditional brickwork.

• Manufacturing and Storage: Production process, standard measurements, and tips for site storage.

• Testing of Concrete Blocks (IS 2185): Understanding Indian Standard requirements for quality control.

Part 4: Binding Materials (Laying aur Plastering ke liye)

• Cement: Manufacturing (Dry and Wet process), Chemical composition aur hydration of cement.

• Types of Cement: OPC (33, 43, 53 grade), PPC, Rapid Hardening, aur Low Heat cement ke uses.

• Field & Lab Tests on Cement: Color test, Fineness test, Setting time (Initial & Final), aur Soundness test.

Part 5: Timber and Wood Products (लकड़ी और इमारती लकड़ी)

• Classification of Trees: Exogenous aur Endogenous trees; Hardwood vs Softwood.

• Structure of Timber: Pith, Heartwood, Sapwood, aur Cambium layer ki pehchan.

• Seasoning of Timber: Natural aur Artificial methods (Kiln seasoning) taaki lakdi tedi na ho.

• Defects in Timber: Knots, Shakes, aur Decay ke karan aur unse bachav.

• Industrial Timber: Plywood, Particle board, Veneers, aur MDF ka modern use.

Part 6: Mortar and Concrete (मसाला और कंक्रीट)

• Mortar: Proportioning of Sand and Cement, workability aur masonry mein iska role.

• Concrete Ingredients: Aggregates (Coarse and Fine), Grading of aggregates aur water-cement ratio.

• Properties of Fresh Concrete: Slump test, Compaction factor, aur Segregation/Bleeding kya hoti hai.

• Admixtures: Concrete ki setting speed badhane ya ghatane wale chemicals.

Part 7: Miscellaneous & Modern Materials (विविध और आधुनिक सामग्री)

• Ferrous and Non-Ferrous Metals: Steel (Mild steel, TMT bars), Aluminum aur Copper ka construction mein use.

• Glass and Plastics: Types of glass (Laminated, Tempered) aur PVC pipes ki properties.

• Paints and Varnishes: Composition of paints, types of distempers aur iron/wood surfaces ki painting.

• Damp Proofing Materials (DPC): Bitumen, Mastic asphalt aur waterproofing compounds.
