POTENTIAL AREAS OF MARBLE SLURRY UTILIZATION

• AS FINE AGGREGATES IN ROAD CONSTRUCTION
• POLYMER BOUND COMPOSITES
• CEMENT BOUND BUILDING PRODUCTS SUCH AS DECORATIVE
  MARBLE COATINGS, BRICKS, TILES AND BOARDS
• LIME AND COLOUR WASHES
• CHEMICAL, COSMATICS AND PAINTS
• AS RAW MATERIAL IN CEMENT MANUFACTURE

11

MARBLE SLURRY IN ROAD CONSTRUCTION

• ABOUT 35 USED IN CONCRETE MIXES FOR ROAD
  PAVEMENT AS FINE AGGREGATE
• STRENGTH, ABRASION RESISTANCE AND DURABILITY OF
  CONCRETE IMPROVED BY THE ADDITION OF MARBLE DUST

SCOPE OF WORK CARRIED OUT AT NATIONAL COUNCIL OF
CEMENT AND BUILDING MATERIALS (NCB), BALLABGARH

• COLLECTION OF MARBLE SLURRY SAMPLES FROM SIX
  MARBLE CLUSTERS AND OTHER RAW MATERIALS FROM SIX
  NEARBY CEMENT PLANTS
• CHARACTERIZATION OF ALL ABOVE SAMPLES
• DESIGNING OPTIMIZATION OF RAW MIXES USING
  MARBLE SLURRY AS RAW MIX COMPONENT
• PREPARATION OF CLINKER AND PERFORMANCE EVALUATION
  OF CEMENTS PREPARED
• PREPARATION AND PERFORMANCE EVALUATION OF
  CEMENT SAMPLES BY INTERGRINDING OF MARBLE
  SLURRY WITH PLANT CLINKER GYPSUM
• TECHNO ECONOMIC VIABILITY STUDY
