UNDERGROUND CONCRETE SURFACE PROTECTION- COAL TAR EPOXY COATING


COAL TAR EPOXY COATING-

Coal tar epoxy coating is a heavy-duty protective polymer that blends epoxy resins with coal tar pitch to form a tough, black, high-solids coating for steel and concrete surfaces. It is prized for its exceptional resistance to corrosion, chemicals, abrasion, and water, making it ideal for use in extremely corrosive and submerged environments like underground pipelines, sewage treatment plants, and marine infrastructure





COMPOSITION OF COAL TAR EPOXY



Field of Application -Corrosion resistant coating for concrete and metal structures such as: 
• Crude oil storage tanks / underground structures 
• Dams, Barrage gates, Penstocks. 
• Foundation walls and sumps. 
• sewage treatment plant, underground pipelines 
• Splash zones in docks & harbors

Application Methodology - 

Surface Preparation 
• Steel: blast cleaned to ISO-Sa21/2 and remove dust, flakes, oil, grease or other loose foreign particles. • In case of new concrete, ensure the concrete is at least 28 days old and remove any loose foreign particles by compressed air. 
• Ensure the ambient temperature is not less than 10 OC and not more than 40OC at the time of coating. • To avoid condensation of moisture onto the coating substrate prior to application, RH should not be above 80% and substrate temperature should be at least more than 3°C above Dew point.

Health and Safety information 
• This product contains coal tar. Avoid contact with eyes and skin.
• Wear suitable protective clothing such as overalls, goggles, dust mask and gloves. Ensure that there is adequate ventilation in the area where the product is being applied. 
• Do not breathe in vapour or spray mist. 
• This product is flammable. 
• Keep away from sources of ignition. 
• Take precautionary measures against static discharge. 
• In case of fire, blanket flames with foam, carbon dioxide or dry chemicals. 
• Eye protection during application is recommended. 
• In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. 
• In case of skin contact, wash with soap and plenty of water. Get medical attention if irritation develops or persists

REINFORCEMENT SPLICING – AS PER IS 456 -2000

Image
  REINFORCEMENT SPLICING – AS PER IS 456 -2000 It Is recommended that splices (Lap) in flexural member should not be at sections where the bending moment is more than 50 percent of the moment of resistance; and not more than half the bars shall be spliced at a section. Where more than one-half of the bars are spliced at a section or where splices are made at point of maximum stress, special precaution shall be taken, such as increasing the length of lap and/or using spirals or closely-spaced stirrups around the length of the splice. Notes:- 1.      Lap splices shall not be used for bars larger than 36 mm ; for larger diameters, bars may be welded; in cases where welding is not practicable, lapping of bars larger than 36 mm may be permitted, in which case additional spirals should be provided around the lapped bars. 2.      Lap splices shall be considered as staggered if the centre to centre distance of the splices is not less th...

WORKABILITY OF CONCRETE - AS PER IS-456-2000

WORKABILITY OF CONCRETE - AS PER IS-456-2000 The concrete mix proportions chosen should be such that the concrete is of adequate workability for the placing conditions of the concrete and can properly be compacted with the means available. Placing Conditions Degree of Workability Slump(mm) Blinding concrete; Shallow sections & Pavements using pavers   Very low In the ‘very low’ category of workability where strict control is necessary, for example pavement quality concrete, measurement of workability by determination of compacting factor will be more appropriate than slump ( see IS 1199 ) and a value of compacting factor of 0.75 to 0.80 is suggested. Mass concrete, Lightly reinforced sections in slabs, beams, walls, columns, Floors; Hand placed pavements; Canal lining; Strip footings     Low     25-75 Heavily reinforced sections in s...
