IS Codes for Building Materials
- 1. IS CODE OF BUILDING MATERIAL IS 3102:- Classification of brick based on the strength IS 3495:- Method of test on brick Part 1:- Compressive strength Part 2:- Water absorption Part 3:- Efflorescence Part 4:- Warpage IS 2386:1963 Testing On Aggregate Part 1:- Shape of aggregate Part 2:- ------------ Part 3:- Specific gravity, water absorption Part 4:-Compressive strength impact test Part 5:-Durability test, hardness test, abrasion test IS 287-1993:- Moisture content in wood 8-16% timber used in building frame 10-16% timber used in window as structure element 12-20% timber used in beam and rafter and structure element as door Weight of timber is taken at 12% moisture content In well-seasoned timber moisture content 10-12% Saw dust can be chemically inert by boiling it in water containing ferrous sulphate As a natural material, timber is Anisotropic
- 2. IS 1141 – 1958 - Seasoning of timber IS 1708 – 1969 - Test for timber performed in laboratory IS 399 – 1963 - Classification of commercial timber and their zorial distribution. IS 269 - 33 grade of cement IS 8112 - 44 grade of cement IS 12269 - 55 grade of cement Strength of cube = .8 * strength of cylinder (80%) SP 23:1982:- Handbook on concrete mix SP 24:1982:- Explanatory handbook on IS 456:2000 SP 34:1987:- Handbook on concrete Reinforcement and detailing IS 1500:- Brinkell hardness test for metallic material IS 1661:- Cement plaster IS 8142 Setting time of concrete Initial setting time for concrete is greater than 1 hours so that concrete remain plastic Time elapsed required for penetration resistance equal to 3.5mpa is called initial setting time of concrete IS 456 Natural source of concrete. Plain and reinforced concrete code of practice IS 383 Specification for coarse and fine aggregate from natural sources of concrete IS516 Methods of tests for strength of concrete (cubes are prepared cured and tested) IS 515 Natural and manufacture aggregate for used in mass concrete Grading of concrete is directly proportional to the WORKABILITY of concrete Density of concrete of increase as size of aggregate increase Max shrinkage take place in concrete after drying for 28 days Addition of sugar increase in setting time by about 4 hr
- 3. Adjustment in various ingredients of concrete if desired slump is not obtained Cementious material 1% Water 1% Aggregate 2% W/C ratio 0 .01% Compressive strength of concrete decrease as size of sample is increase
- 4. Concrete which is made from wastes that are eco-friendly is called as green concrete. Wastes like slag, power plant wastes, recycled concrete, mining and quarrying wastes, red mud, burnt clay, waste glass, saw dust, etc. are used to make green concrete. Blast furnace slag, iron oxides and fly ash are common ingredient of green concrete.
